Circuit/System Testing

WARNING: This page is about a different variant/trim than selected.
IMPORTANT: You must complete the Circuit/System Verification before proceeding with Circuit/System Testing.
  1. Test for less than 1 ohm of resistance between the low reference circuit and ground.
    • If greater than 1 ohm, test the low reference for an open/high resistance. If the circuit tests normal replace the CMP Actuator solenoid.
  2. Test for less than 1 ohm of resistance on the high control circuit.
    • If greater than 1 ohm, test the high control circuit for an open/high resistance. If the circuit tests normal, perform the Component Testing for CMP actuator solenoid.
  3. Inspect the CMP actuator. Refer to CAMSHAFT POSITION ACTUATOR MAGNET REPLACEMENT and CAMSHAFT POSITION ACTUATOR CLEANING AND INSPECTION .
  4. Inspect the engine timing components-Refer to TIMING CHAIN AND SPROCKETS CLEANING AND INSPECTION .
