P0339 OBD Code Definition:
P0339 Crankshaft Position Sensor A Circuit Intermittent
P0339 OBD Code Description:

OBD2 Code P0339 Definition:
The Crankshaft position sensor also known as the crank position sensor is an electronic device used in an engine to record the rate at which the crankshaft is spinning. This information is used by the Powertrain Control Module (PCM) or Electronic Control Module(ECM) to control ignition and fuel injection. The sensor system consists of a rotating part, typically a disc, as well as a static part, the actual sensor. When the engine is running, the high and low parts of the teeth cause the gap with the sensor to change. The changing gap causes the magnetic field near the sensor to change. The change in the magnetic field cause the voltage from the sensor to change. Symptoms

Possible sumptoms of P0339
– Engine Light ON (or Service Engine Soon Warning Light) – Lack/Loss of Power – Engine Stall Possible Causes

Possible causes of P0339
– Harness or connectors (The sensor circuit is open or shorted) – Crankshaft position sensor may be faulty – Signal plate may be damage – Starter motor may be faulty – Starting system circuit – Dead (Weak) battery The Error code is generally activated on detection of the following conditions: – The crankshaft position sensor (POS) signal sent to the ECM is intermittent – The proper pulse signal from the crankshaft position sensor (POS) is not sent to ECM Possible Solutions

– Charge battery – Repair harness or connector – Replaced Crankshaft Position Sensor.
