Today we're testing the camshaft position sensor, along with its harness connector. The sensor consists of a permanent magnet, core and coil. When the engine is running, the gap between the sensor and cam sprocket will periodically change. This generates a voltage and sends the information to the ECM.

Code P0340 could be generated by the following reasons:
- Harness or connectors is open or shorted.
- Camshaft position sensor
- Starter motor / starting system circuit.

Tools Used:
Safety Glasses
10mm wrench
Digital Multimeter (DMM)
