P0343 Camshaft Position Sensor A Circuit Range Performance
P0343 OBD Code Description:
OBD2 Code P0343 Definition:
The Camshaft Position Sensor is an electronic device used in an engine to record the rate at which the camshaft is spinning. This information is used by the Powertrain Control Module (PCM) or Electronic Control Module(ECM) to control ignition and fuel injection. The camshaft position sensor senses the retraction of camshaft (intake) to identify a particular cylinder. The camshaft position sensor senses the piston position. 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. When the crankshaft position sensor (POS) system becomes inoperative, the camshaft position sensor provides various controls of engine parts instead, utilizing timing of cylinder identification signals.
Symptoms
Possible sumptoms of P0343
– Engine Light ON (or Service Engine Soon Warning Light) – Lack/Loss of Power – Engine Stall
Possible Causes
Possible causes of P0343
– Harness or connectors (The sensor circuit is open or shorted) – Camshaft position sensor may be faulty – Camshaft (Intake) 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 camshaft position sensor signal sent to the ECM is too high
Possible Solutions
– Charge battery – Repair harness or connector – Replaced Camshaft Position Sensor.
