Checking Components And Wiring







HINT: Bank 1 (cylinder row nearest the front): cylinders 1, 3, 5 and 7. Bank 2 (cylinder row furthest to the rear, nearest the passenger compartment): cylinders 2, 4, 6 and 8.

- Ignition off
- Disconnect the engine control module (ECM).

Check the signal cable between the control module and the connector for the diagnostic trouble codes (DTC) relevant camshaft position sensor. Check for a short-circuit to ground. Check for a short-circuit to supply voltage. Check for an open-circuit.

Measure between:
- Control module terminal #A33 (#A33) and camshaft position sensor terminal #3 inlet, bank 1 (ECM-P034000).
- Control module terminal #A34 (#A34) and camshaft position sensor terminal #3 inlet, bank 2 (ECM-P034500).
- Control module terminal #A31 (#A31) and camshaft position sensor terminal #3 exhaust, bank 1 (ECM-P036500).
- Control module terminal #A32 (#A32) and camshaft position sensor terminal #3 exhaust, bank 2 (ECM-P039000).

Check the voltage supply cable between the control module and the connector for the diagnostic trouble codes (DTC) relevant camshaft position sensor. Check for a short-circuit to ground. Check for a short-circuit to supply voltage. Check for an open-circuit.

Measure between:
- Control module terminal #A72 (#B12) and camshaft position sensor terminal #1.

Check the ground lead between the control module and the connector for the diagnostic trouble codes (DTC) relevant camshaft position sensor. Check for a short-circuit to ground. Check for a short-circuit to supply voltage. Check for an open-circuit.

Measure between:
- Control module terminal #A07 (#A7) and camshaft position sensor terminal #2.

Remedy as necessary.
