  • Engine Control Module (ECM): ECM is the part of the car computer that controls the engine system and performance. Problems lead to poor fuel economy, engine stalling & unwanted engine vibrations

Possible Solutions:

  • Inspect and repair any damaged wiring or connections in the actuator supply voltage 'A' circuit

  • Replace the actuator supply voltage 'A' sensor

  • Tighten or clean any loose or corroded electrical connections

  • Replace the engine control module (ECM) if necessary
