Circuit/System Testing
- Ignition OFF, disconnect the IC module connector. Test for less than 1 ohm on the camshaft position signal circuit IC module terminal J.
- If greater than the specified value, test the camshaft position signal circuit for an open/high resistance.
- Inspect the CMP sensor for looseness and correct installation.
- If the sensor is loose, inspect the sensor and the O-ring for damage, replace as necessary.
- Inspect the engine for the following conditions:
- Engine oil for debris and contamination
- Crankshaft reluctor wheel for damage
- The timing chain, tensioner, and sprockets for wear or damage
- If debris is found in the engine oil, inspect the internal engine components to determine the cause. Repair or replace any worn or damaged components.
- If the camshaft position signal circuit, CMP sensor and engine timing components test normal, replace the IC module.
