Hi,

The code is specific to the inlet camshaft position sensor. Either we have a faulty sensor, or there is a short to ground, power, or an open circuit.

With that in mind, inspect the wiring and connector at the sensor. If everything appears good, chances are the sensor is faulty,

I attached the directions below for replacing the sensor. Take a look through them and let me know if you have questions.

Take care,

joe
