Details of the p023c OBD Code
P023C code indicates a turbocharger boost sensor B circuit high.
OBD code P023C means that the fuel pump secondary circuit has a high voltage condition.
This code is triggered by the Engine Control Module (ECM) when it detects that the voltage in the fuel pump secondary circuit is higher than specified parameters.
The fuel pump secondary circuit is part of the fuel pump control system, which regulates the fuel pump’s operation to ensure proper fuel delivery to the engine.
Mechanic’s Tech Notes
Code P023C relates to the turbocharger boost sensor B circuit having a high voltage condition.
OBDII code P023C indicates a problem with the turbocharger boost sensor A circuit.
To diagnose, use a voltmeter to check the sensor’s power and ground.
Scan tools can help verify sensor data over the CAN network.
Inspect the wiring harness and connectors for damage, corrosion, or loose connections.
Ensure connector pins are intact.
If no visible issues, test the sensor’s resistance and compare it to specifications.
Reflashing the engine control module may be necessary if all other components check out.
