Diagnostic Fault Information



Circuit/System Description



Each camshaft is equipped with a camshaft position sensor that the engine control module (ECM) monitors. The camshaft position sensor is a hall



effect switch that works in conjunction with a 4X reluctor wheel. The reluctor wheels are mounted to the camshaft position actuators that are



mounted to the end of the camshafts. The ECM uses the camshaft position sensor signals in order to determine the position of the camshafts. The



ECM supplies 5 V to the camshaft position sensors on the 5 V reference circuits, and supplies a ground on the low reference circuits. The camshaft



position sensors provide a signal to the ECM on the signal circuits. If the ECM detects extra or missing camshaft position sensor signal transitions,



or a signal voltage that is more or less than the predetermined range, within a certain number of crankshaft revolutions, one of these DTCs sets.



Conditions for Running the DTC



* The ECM detects greater than 10 crankshaft revolutions.



* The engine speed is less than 2,520 RPM.



* The DTCs run continuously once the above condition is met.



Conditions for Setting the DTC



P0341, P0346, P0366, P0391



* The ECM detects a signal from the camshaft position sensor, but the number of pulses are less than or greater than what is expected for one



crankshaft revolution.



OR



* The camshaft position sensor does NOT correlate to the crankshaft position.



* Either condition must exist for greater than 1 s, or cumulative of 10 s.



P0342, P0347, P0367, P0392



The camshaft position sensor signal voltage is always low and the ECM detects no pulses from the camshaft position sensor for greater than 1 s, or



cumulative of 10 s.
