Quick Answer

Kubota has no single master list of tractor fault codes. The code format depends on the tractor: L3901 shows E-xx codes on the LCD, M6060 and M7060 show ERROR-xx, Eng NG or ECU NG, and common-rail engines (V2607, V3307, V3800-CR) use P-codes (such as P0016 or P3006) that a dealer reads with a diagnostic tool. For every operator-level code in Kubota’s manuals, the instruction is the same: contact your local Kubota dealer. Every code below comes from a Kubota manual and lists its source page.

Updated October 2026. Codes we could not confirm in a Kubota document are marked NOT FOUND, not guessed.

How Kubota Shows Fault Codes

Kubota’s operator’s manuals say that when something is wrong with the power train, the master system warning indicator blinks and a code appears on the liquid-crystal display. The code stays on automatically. The manuals we checked do not give a button sequence for recalling stored codes (NOT FOUND), and they do not give an operator reset procedure.

Tractor	How the fault appears	Status on this page
L3901 (and L3301)	E-20, E-31, E-40, E-75, E-84, E-93, E-94 on the LCD	Verified, full list below
M6060 / M7060	ERROR-1 to ERROR-99, Eng NG, ECU NG on the LCD	Verified, full list below
V3800-CR-TE4 / TIE4 engines (M8560, M9960)	P-codes and U-codes, read with a dealer diagnostic tool	Headings and pages verified; 8 full entries
V2607 / V3307 common-rail engines	P-codes with J1939 SPN/FMI numbers, read with a dealer diagnostic tool	Three codes verified (P0016, P0072, P0087)
L4701	E-93, E-94 and E-95 appear in the indexed manual text	Not page-verified, so not listed as a table
L6060, M5-111, MX5400, M8540	Dealer-level engine and DPF diagnosis	Operator code table NOT FOUND
BX2380, B2601, L2501	Warning lamps. Whether ECU codes exist is not confirmed	NOT FOUND

Kubota L3901 Error Codes (E-xx)

Source for this table: L3301/L3901 Operator’s Manual, “Power Train Troubleshooting,” printed p. 91. Kubota’s introduction says to immediately contact your local Kubota dealer for repairs if an error code appears. Related guide: Kubota L3901 Problems.

Code	Meaning (Kubota’s wording)	Kubota’s stated action
E-20	“Communication trouble”	Contact your local Kubota dealer.
E-31	“Meter’s part code and ECU model setting not compatible”	Contact your local Kubota dealer.
E-40	“Input voltage of lever sensor from ECU is in trouble.”	Contact your local Kubota dealer.
E-75	“Acceleration sensor output out of spec”	Contact your local Kubota dealer.
E-84	“Acceleration sensor maladjusted”	Contact your local Kubota dealer.
E-93	“Relay for engine starter motor is in trouble.”	Kubota: “The engine cannot start.” Contact your local Kubota dealer.
E-94	“Relay for engine shut off is in trouble.”	Kubota: the Operator Presence Control (OPC) system activates and “the engine stops itself.” Contact your local Kubota dealer.

What E-94 Means in Practice

E-94 is the code people search most. Kubota words it as a fault in the engine shut-off relay and says the OPC system activates and the engine stops itself. If your L3901 keeps dying and shows E-94, see Kubota Shuts Off While Running for the restart-pattern checks, then take it to a dealer. Kubota does not publish a repair procedure on this manual page.

Note: other write-ups word this code as “relay for engine stop.” The wording above is quoted from the L3301/L3901 operator’s manual.

Kubota M6060 and M7060 Error Codes (ERROR-xx)

Source for this table: M6060/M7060 Operator’s Manual, “Power Train Troubleshooting,” printed p. 119. The same page covers both tractors, and the codes and wording are identical. Related guides: M6060 Problems and M7060 Problems.

Code	Meaning (Kubota’s wording)	Kubota’s stated action
ERROR-1	“Acceleration sensor (main) trouble”	Contact your local Kubota dealer.
ERROR-2	“Acceleration sensor (sub) trouble”	Contact your local Kubota dealer.
ERROR-3	“Acceleration sensor main/sub phase shifting trouble”	Contact your local Kubota dealer.
ERROR-11	“PTO relay trouble”	Contact your local Kubota dealer.
ERROR-12	“4-wheel-drive solenoid trouble”	Contact your local Kubota dealer.
ERROR-21	“Range gear shift (Hi) switch trouble”	Contact your local Kubota dealer.
ERROR-22	“Range gear shift (6th) switch trouble”	Contact your local Kubota dealer.
ERROR-23	“Shuttle rotating sensor or switch(*1) trouble”	Contact your local Kubota dealer.
ERROR-24	“Machine speed sensor or switch(*1) trouble”	Contact your local Kubota dealer.
ERROR-25	“DPF regeneration malfunction trouble”	Contact your local Kubota dealer.
ERROR-60	“Analog reference supply voltage +5V trouble”	Contact your local Kubota dealer.
ERROR-63	“Acceleration & engine adjustment trouble”	Contact your local Kubota dealer.
ERROR-99	“Communication trouble”	Contact your local Kubota dealer.
Eng NG	“Engine communication trouble” (Kubota remark: “Engine trouble, etc.”)	Contact your local Kubota dealer.
ECU NG	“ECU communication trouble” (Kubota remark: “ECU trouble, etc.”)	Contact your local Kubota dealer.

Footnote *1 in Kubota’s table identifies the range gear shift (Hi) and range gear shift (6th) switches.

ERROR-25: the DPF Code

ERROR-25 is the one DPF-related code in Kubota’s operator-level table. Kubota calls it “DPF regeneration malfunction trouble” and directs you to the dealer. The row gives no regeneration procedure and no immediate-stop instruction. For general regen background, see DPF Regen Failures.

Kubota’s Engine Warning Indicator Instruction

On the same M6060/M7060 page, for “engine not overheated, but engine warning indicator on,” Kubota says: “Stop the engine and get it restarted.” If the engine fails to restart or the indicator stays on, “immediately contact your local KUBOTA dealer.” Kubota lists possible effects as the engine stopping unexpectedly, failing to start or stalling just after start, and not enough engine output. This instruction is not tied to any one numbered code.

A code-by-code power-derate list is NOT FOUND.

Common-Rail Engine P-Codes (Dealer Tool Codes)

Kubota’s Common Rail System Diagnosis Manual (V2607-CR-E4B, V2607-CR-TE4B, V3307-CR-TE4B and related variants, March 2015) organizes procedures by P-code and J1939 SPN/FMI number. These are engine-controller codes. They are not shown as E-xx or ERROR-xx on the dash, and which tractors use these engine variants is not confirmed here.

Code (P-code / SPN-FMI)	Kubota’s heading	Diagnosis page
P0016 / 636-7	“NE – G Phase Shift”	1-S123
P0072 / 171-4	“Intake Air Temperature Built-in MAF Sensor: Abnormality” (Low entry; P0073 is the matching High entry)	1-S124
P0087 / 633-7	“Pressure Limiter Emergency Open”	1-S127

The manual includes variant-dependent equipment, so a code listed there does not apply to every engine variant. We have not substituted generic automotive wording for Kubota’s headings. Cause and action text for these three codes is NOT FOUND, so none is given.

Kubota V3800-CR-TE4 / TIE4 Common-Rail Codes (M8560, M9960)

Source: Kubota Diagnosis Manual, Common Rail System, V3800-CR-TE4, V3800-CR-TIE4 (KiSC issued May 2012), referred to here as the 2012 manual. Page numbers are Kubota’s printed pages. Kubota’s indexed specifications list the M8560 with the V3800-CR-TE4 and the M9960 with the V3800-CR-TIE4 (specifications page not inspected). The manual presents one shared code list for both variants.

Check Your Engine First

Not every V3800 tractor uses this list. Kubota’s M6 operator’s manual lists the M6-131 and M6-141 with the V6108-TIEF4 engine and the M6-101 and M6-111 with the V3800-TIEF4, which is not the engine named on this manual’s cover. We did not apply these codes to those tractors. The older M8540 and M9540 use a different V3800 engine, so these codes were not assigned to them either.

P3006 and P3007: A Warning, Not Always a Fault

For P3006 Kubota notes: “This DTC means the warning to urge to start regeneration rather than error. (Basically, Service Call is not necessary.)” Listed causes include continuing low-load operation, frequent idling and repeated runs shorter than 30 minutes. For P3007 the note says a manual regeneration has not been carried out and to start it as soon as the manual regeneration warning light comes on. Note that Kubota’s P3007 wording refers to a diagnostic-tool active test. See DPF Regen Failures and DPF Cleaning.

A later TE4(C)/TIE4(C) edition lists P3008 with output limited to about 50% and the instruction “Replace the DPF.” We could not retrieve P3008 in the 2012 manual, so it is shown below by heading only.

Other Codes in the 2012 Manual (Heading and Page Only)

For these codes we verified Kubota’s heading and the page where its diagnostic procedure starts. Kubota’s cause and ECU response for each were not retrieved, so none is given here.

Later edition: an index excerpt for the TE4(C)/TIE4(C) manual also lists P0111 (“Intake air temperature: high (Inter cooler model only)”), P0181 (“Fuel high temperature”), P1990 to P1992 (“EEPROM check sum error”), P2122/P2123 and P2127/P2128 (accelerator position sensor abnormality), P2135 (accelerator position sensor correlation error), P3019, P3023, P3025 and U0084 to U0089. These are not in the 2012 contents we inspected, and the edition’s full identity was not found, so they are not placed in the table above.

Why You May See Other Codes Elsewhere

Code-lookup sites often list generic OBD-II codes (the P0xxx style) for Kubota tractors. We found P-codes in Kubota manuals only for specific common-rail engines (V2607, V3307 and V3800-CR, shown above), each with its own manual and page numbers. A code can differ in wording or response between engines and manual editions. We did not apply one engine’s list to another, and we left out entries we could not verify. If your tractor shows a code not listed here, write it down with the model and serial number and give it to your dealer.

Before You Call the Dealer

Several codes above involve relays, sensors or the 5V supply (E-93, E-94, ERROR-11, ERROR-60). Low battery voltage and corroded connections cause electrical faults, so check these first. This does not replace Kubota’s dealer instruction. It makes the dealer visit faster. See Kubota Electrical Systems.

Should You Clear Codes Yourself?

Kubota’s manuals we checked do not give an operator procedure for clearing codes, so we cannot give you one. The fault should be repaired first, and the dealer clears it with the diagnostic tool. Clearing a code without fixing the cause does not fix the cause, and a recurring DPF or engine-stop fault can leave you stopped in the field.

What We Could Not Verify

Complete engine-controller fault lists for L3901, L4701, L6060, M5-111, MX5400 and M8540.
Operator code tables for L4701 (E-93, E-94, E-95 are indexed but not page-verified), M5-111, L6060 HST, MX5400 and M8540.
A no-laptop procedure for recalling stored codes on any model.
Whether BX2380, B2601 and L2501 have ECU fault codes or warning lamps only.
Cause and action text for P0016, P0072 and P0087 in the V2607/V3307 manual, and which tractors use those engines.
Most V3800-CR causes and ECU responses: derate percentages, shutdown timers and voltage or temperature thresholds were verified only for the eight entries shown in full. We specifically could not confirm forced-stop timers for P0192/P0193 or any engine-stop behavior for P0524.
The full V3800 code index. We did not audit every page, so a code missing here is not proof it does not exist.
The page-level applicability of the V3800-CR list to M8560 and M9960 beyond Kubota’s engine listing.
Code-by-code DPF inhibit, shutdown and power-derate behavior.

How We Verified This Page

Every code was checked against Kubota-authored manual text: the L3301/L3901 operator’s manual, the M6060/M7060 operator’s manual, and Kubota’s Common Rail System Diagnosis Manuals for the V2607/V3307 and V3800-CR engines. For most V3800 codes we verified only Kubota’s contents listing, so those rows show heading and page only. These copies are hosted by third parties (ManualsLib and Scribd), not by Kubota, and we show printed page numbers. Forums and code-lookup sites were not used as evidence. Always confirm against the manual for your exact serial number range.

Frequently Asked Questions

What does E-94 mean on a Kubota L3901?

Kubota’s L3301/L3901 operator’s manual (printed p. 91) says “Relay for engine shut off is in trouble,” and that the OPC system activates and the engine stops itself. Contact your dealer.

Does Kubota publish one list of all tractor error codes?

We found no single public master list. Codes appear in each tractor’s operator’s manual and in engine-family diagnosis manuals, so you need the manual for your model.

What does ERROR-25 mean on an M6060 or M7060?

Kubota calls it “DPF regeneration malfunction trouble” (printed p. 119) and says to contact your local Kubota dealer.

Are P0016, P0072 and P0087 Kubota tractor codes?

Kubota’s Common Rail System Diagnosis Manual lists them for V2607 and V3307 common-rail engines: P0016 as “NE – G Phase Shift,” P0072 as an intake air temperature sensor entry, and P0087 as “Pressure Limiter Emergency Open.” Which tractors use those engines is not confirmed here.

What do P3006 and P3007 mean on a Kubota with a DPF?

On V3800-CR engines Kubota lists P3006 and P3007 as excessive PM (soot) warnings, with output limited to about 50%. For P3006 it says to start a DPF manual regeneration immediately and that a service call is basically not necessary. For P3007 it refers to a diagnostic-tool active test (1-S267 and 1-S268).

Does the M8560 use these V3800-CR codes?

Kubota’s indexed specifications list the M8560 with the V3800-CR-TE4 and the M9960 with the V3800-CR-TIE4. The M6-131 and M6-141 use a different engine, the V6108-TIEF4, so check your engine before using this list.

Can I reset a Kubota error code myself?

The Kubota manuals we checked give no operator reset procedure. Kubota says to contact the dealer when a code appears, so the dealer fixes the cause and clears the code.

Do the BX2380, B2601 and L2501 have error codes?

We could not confirm. Kubota’s BX manual text refers to warning lamps in the Easy Checker, but we could not verify whether any ECU fault codes exist for these models.
