Circuit/System Testing

  1. Test for less than 1 ohm of resistance on the camshaft position signal circuit.
    • If greater than the specified value, test the camshaft position signal circuit for an open/high resistance.
  2. Ignition OFF, 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.
  3. 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.
  4. If the camshaft position signal circuit, CMP Sensor and engine timing components test normal, replace the IC module.
