Code P0339 Acura Description

The Crankshaft Position (CKP) sensor detects injection/ignition timing for each cylinder and engine speed. The CKP sensor consists of a rotor and a semiconductor that detects the rotor position. When the engine starts, the rotor turns, and the magnetic flux in the semiconductor device changes. The magnetic flux changes are converted into pulsing signals to the Powertrain Control Module (PCM). If an abnormal amount of pulsing signals from the CKP sensor are detected, the PCM detects a malfunction and stores a Diagnostic Trouble Code (DTC).
