- 2With a multimeter, check that the supply wire to the sensor is not shorted to ground or to system voltage
- 3Look along the supply wire to the fuel pressure sensor for chafed or pinched spots
- 4If the fault remains, have a workshop check the fuel pressure sensor and the control module
Symptome, die Sie bemerken können2
