Checking the Operation Sound

WARNING: This page is about a different car, the 2014 Mitsubishi Outlander. However, it is still accessible from the selected car via links, so may be relevant.
  1. Check that the operation sound of the stepper motor can be heard from the EGR valve when the ignition switch is turned ON (without starting the engine).
  2. If the operation sound cannot be heard, inspect the drive circuit of the stepper motor.
    NOTE: If the operation sound is not heard, and the circuit is normal, either the stepper motor or the ECM may have failed.
