Check for a loss of 5 volts on the Gray wire to the manifold absolute pressure (MAP) sensor. Check the signal voltage on the Green wire. Inspect the wire harness by the connector at the coil. Wiggle tug test the wire harness and check for a glitch. Check the power and ground feed to the cam sensor for missing. It should have 12 volts on the Red/White wire and a ground on the Black wire at pin C of the sensor. Disconnect the cam sensor and the Powertrain Control Module (PCM), and verify that the Brown/White wire is not open or shorted to ground. If all are OK, plug the sensor back in and probe the Black wire at pin B. See if there is a square wave signal while the engine is running. If no signal, then replace the cam sensor.
