Circuit/System Testing

WARNING: This page is about a different variant/trim than selected.
  1. Measure the CMP actuator solenoid for the following specified resistance for the given temperature.
    • 3.25-3.66 ohms at 40°C (40°F)
    • 4.0-4.5 ohms at 20°C (68°F)
    • 4.0-4.52 ohms at 25°C (77°F)
    • 5.6-6.4 ohms at 125°C (257°F)
    • If the resistance is not at the specified value for the given temperature replace the affected CMP actuator solenoid.
  2. Disconnect the ECM. Test the affected CMP actuator solenoid control circuit for less than 2.5 ohms of resistance.
    • If the resistance is more the 2.5 ohms repair the circuit as needed.
  3. Test the affected CMP actuator solenoid ground circuit for less than 2.5 ohms of resistance.
    • If the resistance is more the 2.5 ohms repair the circuit as needed.
  4. Inspect for the following conditions
    • Degraded oil quality, incorrect oil viscosity, and improper oil level
    • Improper alignment of the CMP actuator solenoid to the oil control valve
    • Low engine oil pressure
    • Oil pressure leaks and restrictions in the dedicated oil passages from the oil filter to the affected CMP actuator
    • A slow moving or sticking oil control valve
    • A loose primary or secondary timing chain
    • If no condition is found, replace the ECM.
