P018D

DTC P018D, sometimes indicated as P018D00 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing fuel pressure sensor "b" circuit high.

This code is set when the PCM detects a high voltage condition on the fuel pressure sensor B circuit.
Possible causes include a short to voltage in the sensor harness, a bad fuel pressure sensor, or a faulty PCM.
If the code is caused by a short to voltage in the sensor harness, the harness should be repaired or replaced. If the code is caused by a bad fuel pressure sensor, the sensor should be replaced. If the code is caused by a faulty PCM, the PCM should be replaced.

• P018D: Fuel Pressure Sensor B Circuit High
• P018D: Fuel Pressure Sensor "B" Circuit High
• P018D: Fuel pressure sensor B – circuit high
• P018D 00: Fuel pressure sensor B - circuit high

These codes are commonly diagnosed with error code P018D.

• P018C [1] Fuel Pressure Sensor "B" Circuit Low
• P0087 [1] Fuel Rail/System Pressure - Too Low
• P00C6 [1] Fuel rail pressure (FRP) – engine cranking – pressure too low
• P008B [1] Low Pressure Fuel System Pressure - Too High
• P008A [1] Low Pressure Fuel System Pressure - Too Low
