Checking The Components And Wiring

HINT: If the diagnostic trouble code (DTC) for incorrect camshaft position is stored, fault-tracing for this diagnostic trouble code (DTC) must be carried out first.

Check the connector for the camshaft position (CMP) sensor. Check for contact resistance. Check for oxidation.

Check that the camshaft position (CMP) sensor is securely installed in the correct position.

Check the signal cable between engine control module (ECM) terminal #A64 (#B4) and camshaft position (CMP) sensor connector terminal #3. Check for an intermittent short-circuit to ground. Check for an intermittent short-circuit to supply voltage. Check for an intermittent open-circuit.

Check the ground lead between control module terminal #A43 (#A43) and camshaft position (CMP) sensor connector terminal #2. Check for an intermittent short-circuit to supply voltage. Check for an intermittent open-circuit.

Check the power supply cable between control module terminal #A39 (#A39) and camshaft position (CMP) sensor connector terminal #1. Check for an intermittent short-circuit to ground. Check for an intermittent short-circuit to supply voltage. Check for an intermittent open-circuit.

HINT: With the ignition on and the camshaft position (CMP) sensor connector disconnected, the voltage between terminal #1 and ground must be approximately 5 V.

Remedy as necessary.
