Symptoms of a Failing Camshaft Position Sensor

Although tucked out of sight and securely fastened to the engine, the camshaft position sensor can be prone to fail. After all, it’s a delicate plastic housing with two wires and a sensor head the size of a thumb that fits into the cylinder head. Failures can include a cracked plastic housing, an internal short in the circuit, degradation or corrosion in the connector, or mechanical damage or impact to the sensor head.

How can you tell that the cam sensor is faulty? There are a few common symptoms that can lead you to diagnose the camshaft sensor as the culprit. You could have difficulty starting the engine since the onboard computer is having a tough time identifying TDC. The Check Engine Light may come on with a P0340 fault code in the powertrain control module. You might also feel a loss of power or stalling, poor fuel mileage, or your car could go into a protective mode referred to as ‘limp-in’ mode that limits its performance.
