DTC codes / P02xx · Fuel and air metering (injector circuits) / P023E
P023E indicates that the powertrain control module (PCM) has detected a correlation error between the manifold absolute pressure (MAP) sensor and the turbocharger/supercharger boost sensor B. The PCM compares the two pressure signals under specific operating conditions and flags the code when they deviate beyond an acceptable threshold, suggesting a sensor, wiring, or mechanical issue.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
