DTC P018D Cadillac
Fuel Pressure Sensor Circuit High Voltage
Fuel Pressure Sensor Circuit High Voltage
Description
The engine is running. DTC P018C, P018D, P0231, P0232, P023F, P064A, P1255 or P06A6 are not active. DTC P0641 has not failed this ignition cycle. Fuel pump control is enabled and the fuel pump control state is normal. The engine has been running for at least 5 seconds.
Cause and Solution
The fuel pump control module does not detect a change in the fuel rail pressure of at least 30 kPa (4.4 psi) when the fuel pump is operating. The fuel rail pressure sensor performance diagnostic provides a means to detect fuel pressure sensor output that is stuck within the normal operating range of the sensor.
