J1939 code SPN 190. Below — how the fault is worded at the factory by DAF, Dongfeng, Foton, Isuzu, KAMAZ, MAZ, Renault Trucks, YaMZ and ZF AS-Tronic, and what the second half of the code (FMI) means in the standard.

| FMI 0 | Crankshaft speed F552 engine overspeed |
| FMI 2 | Crankshaft speed F552 signal missing/implausible |
| FMI 0 | Engine speed too high |
| FMI 2 | No signal from the crankshaft speed sensor. Effect: Diagnostic functions may be limited. |
| FMI 8 | Crankshaft speed sensor fault. Effect: Gearbox functions may be limited. |
| FMI 0 | Overrun (P0219) |
| FMI 0 | Engine speed. K-line code on KamAZ-5490: MR2 10530. |
| FMI 7 | Crankshaft and camshaft signal mismatch |
| FMI 11 | Crankshaft speed sensor: no/invalid signal |
| FMI 12 | Crankshaft speed sensor: no/invalid signal |
| FMI 7 | Mismatch between crankshaft and camshaft speed sensor signals - Camshaft gear installed incorrectly. Blink code: 1-1-4. The engine will not start. Power will be reduced. Repair: Check the camshaft and crankshaft speed sensors and their wiring. |
| FMI 11 | Crankshaft speed sensor circuit fault - Incorrect sensor signal. Blink code: 1-1-2. Power will be reduced. Repair: Check the crankshaft speed sensor and its wiring. |
| FMI 12 | Crankshaft speed sensor circuit fault - No signal from sensor. Blink code: 1-1-2. Power will be reduced. Repair: Check the crankshaft speed sensor and its wiring. |
| FMI 0 | Parameters out of limits. Repair: Perform the programming. |
| FMI 2 | Flywheel speed sensor — signal lost while the engine is running, open or short circuit. Repair: Check the sensor and the wiring (J 1/30, J 1/31). Check the sensor and the engine wiring (A 29, A 37). Check the sensor, the flywheel and the engine wiring (A 29, A 37). |
| FMI 5 | Pump injection timing does not match the flywheel reference (out of phase), or the speed sensor circuit is open. Repair: Check the sensor and the engine wiring (A 29, A 37). Check the sensor, the flywheel and the engine wiring (A 29, A 37). Check the flywheel and pump timing. |
| FMI 8 | Crankshaft speed sensor (on the flywheel): engine started without the sensor. Repair: Check the sensor and the wiring (J 1/30, J 1/31). |
| FMI 7 | Mismatch between crankshaft and camshaft speed sensor signals (Camshaft gear incorrectly installed). Blink code: 1-1-4. The engine will not start. Power will be reduced. Repair: Check the camshaft and crankshaft speed sensors and their wiring. |
| FMI 11 | Crankshaft speed sensor circuit fault (Incorrect sensor signal). Blink code: 1-1-2. Power will be reduced. Repair: Check the crankshaft speed sensor and its wiring. |
| FMI 12 | Crankshaft speed sensor circuit fault (No signal from sensor). Blink code: 1-1-2. Power will be reduced. Repair: Check the crankshaft speed sensor and its wiring. |
ZF AS-Tronic uses its own fault numbering: the number in the table below is an internal ZF code, not a J1939 SPN. It matches the title of this page by digit only and means something different.
| FMI 0 | EEPROM programming parameter out of range. |
Do not drive. Stop as soon as it’s safe to do so — don’t keep going.
The code is flagged critical: the manufacturer considers it unsafe to keep driving without checking.
This code alone cannot say what will fail next, so stop at the first safe opportunity and look at it on the spot.
That said, the manufacturer flags this code as critical — if in doubt, it is safer to stop and check on the spot.
This code is often not the fault itself but a knock-on. If any of these is in the same readout, start with it:
