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.
- 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).
- 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.
