P0342 CHEVROLET - Camshaft Position Sensor Circuit Low Voltage
P0342 CHEVROLET Possible Causes
- Faulty Camshaft Position Sensor
- Camshaft Position Sensor harness is open or shorted
- Camshaft Position Sensor circuit poor electrical connection
- Faulty starter motor
- Starting system circuit
- Dead (Weak) battery
P0342 CHEVROLET Tech NotesSometimes and in some models, low battery voltage or a weak starter can trigger a Camshaft Position Sensor code.
Cost of diagnosing the P0342 CHEVROLET code
Labor: 1.0The cost of diagnosing the P0342 CHEVROLET code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.
When is the P0342 CHEVROLET code detected?The camshaft position sensor signal is sent the Powertrain Control Module (PCM) is too low
P0342 CHEVROLET Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of Power
- Engine Stall
P0342 CHEVROLET MeaningThe 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 Engine 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.
