J1939 code SPN 3232. Below — how the fault is worded at the factory by SITRAK, and what the second half of the code (FMI) means in the standard.
| FMI 3 | HEGO sensor short circuit to power supply |
| FMI 4 | HEGO sensor short circuit to ground |
| FMI 14 | Incorrect data length of the AT1OGC2 CAN frame. Effect: Torque limited, MIL on, power may drop to 60%. |
| FMI 19 | Incorrect data length of the AT1OGC2 CAN frame. Effect: Torque may be limited. |
Safe to drive. Below — how much time you have and what happens if you keep going.
This is an electrical fault: an open, a short or a bad contact in the sensor circuit. The value it measures is most likely fine.
You can drive. But until the circuit is repaired this system runs blind and cannot warn you about a real failure.
