Monitor Description
If the output voltage of the fuel pressure sensor is outside specifications, DTC is set. The DTCs indicate open/short condition in the sensor circuits.
If these DTCs are set, the ECM switches to fail-safe mode, and the engine output is limited.
Fail-safe mode continues until the vehicle is turned to IG OFF.
