  • 4 cylinders

  • If the sensor is OK, then you may have a problem with the timing belt. Other than the Camshaft Position Sensor and the Timing Belt, I have not seen any other component setting the P0340 code.

  • Disconnect Camshaft Position Sensor harness connector. Measure resistance between Camshaft Position Sensor terminals (component side). Resistance should be 835-1400 ohms (cold sensor), and 1060-1645 ohms (hot sensor). If resistances are not as specified, replace Camshaft Position Sensor.
