This code indicates a problem with the camshaft position circuit, the whole thing the sensor itself, wiring or pcm. Outside of the sensor itself failing you could also have the following conditions.

* a wire or connector in the circuit could be grounded/shorted/broken
* the PCM may have failed
* there exists an open circuit
* the crankshaft position sensor may have failed

So obviously if you replace the sensor and the problem returned then that's not it. So you want to check the wiring for continuity make sure the sensor is in operating voltage, also check the voltage and wiring of the crank position sensor.

There is a history of experience of bad alternators flipping that code. I would check the ALT too if I were you.

157dB

THIS will tell you where to go and what to check....
Just like Ford would.
