What the carmd code p1391?

Answer 1

The OBD-II trouble code P1391 indicates a problem with the camshaft position sensor or its circuit, specifically in Honda and Acura vehicles. This code often suggests a malfunction in the sensor's signal or a timing issue, which can lead to poor engine performance or stalling. To diagnose this issue, technicians typically check the sensor, its wiring, and the engine timing. Clearing the code without addressing the underlying problem may lead to a recurrence.
