Checking The Components And Wiring

Check the signal cable between engine control module (ECM) terminal #A63 (#B3) and camshaft position (CMP) sensor connector terminal #3. Check for a short-circuit to ground. Check for a short-circuit to supply voltage. Check for an open-circuit.

Check the ground lead between engine control module (ECM) terminal #A19 (#A19) and camshaft position (CMP) sensor connector terminal #2. Check for a short-circuit to supply voltage. Check for an open-circuit.

Check the power supply cable between engine control module (ECM) terminal #A17 (#A17) and camshaft position (CMP) sensor connector terminal #1. Check for a short-circuit to ground. Check for a short-circuit to supply voltage. Check for an 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.
