How to fix P0339 Code: Crankshaft Position Sensor “A” Circuit Intermittent
The computer (ECM/PCM) monitors the engine timing using the Crankshaft Position Sensor (CKP). This allows for the ignition (spark) at the correct time.
A P0339 code is set when the computer (ECM/PCM) detects the crankshaft position sensor is out of a specified range.
Some vehicles have a Crankshaft Position Sensor Re-Learn Procedure
Possible Causes of a P0339 Code:
Faulty Crankshaft Position Sensor
Wiring Issue (Sensor harness has open or short)
Blown Fuse
Engine Timing Off (timing Belt/Chain, tensioner)
