How do you fix code p0340 on a 2002 Saturn s-series?

Answer 1

The code P0340 indicates that the control computer detected a problem with the camshaft position sensor CIRCUIT. Since the code indicates that it's the circuit, there could be a problem with the sensor, the wiring or the PCM.

If you just replace the CPS, you may not solve the problem, especially if it's a wire, connector or the control computer.
