Valtra Error Codes May 2026

| Code | Description | Likely Cause | | :--- | :--- | :--- | | SPN 94 FMI 1 | Fuel Pressure Low | Clogged fuel filter, air in fuel system, faulty fuel pump. | | SPN 100 FMI 1 | Engine Oil Pressure Low | Low oil level, worn oil pump, faulty oil pressure sensor. | | SPN 110 FMI 0 | Engine Coolant Temp High (Overheat) | Blocked radiator, low coolant, faulty thermostat. | | SPN 111 FMI 1 | Coolant Level Low | Leak in cooling system, faulty level sensor. | | SPN 157 FMI 1 | Rail Fuel Pressure (Common Rail) | Injector leak, pressure relief valve stuck open. | | SPN 2791 FMI 5 | EGR Valve Position | EGR valve stuck open/closed, carbon buildup. | | SPN 3362 FMI 3 | SCR System (DEF/AdBlue) Quality | Poor quality DEF fluid, crystallization in tank. |

Preventative maintenance drastically reduces the occurrence of fault codes:

Valtra releases TSBs (Technical Service Bulletins) for known software glitches. For example, an error code SPN 3364 on early T4 models was often a software bug, not a failed NOx sensor. A dealer flash fixes it. valtra error codes

❗ Driving with a critical engine code can turn a $200 sensor into a $15,000 repair. | Code | Description | Likely Cause |

While there are hundreds of potential codes, they generally fall into three main categories based on severity.

| FMI | Meaning | Example | |-----|---------|---------| | 0 | Data valid but above normal | Pressure too high | | 1 | Data valid but below normal | Pressure too low | | 2 | Data erratic / intermittent | Loose sensor | | 3 | Voltage above normal | Short to high | | 4 | Voltage below normal | Short to ground | | 7 | Mechanical system not responding | Stuck actuator | Valtra releases TSBs (Technical Service Bulletins) for known
