Check Engine Light Diagnostics

The check engine light is your vehicle’s way of alerting you that something is wrong with the engine or emissions system.


Our technicians use advanced diagnostic equipment to read fault codes and identify the source of the problem. Once the issue is identified, we explain the recommended repair so you can make an informed decision.

  • Common reasons the check engine light may turn on include:

    • Faulty oxygen sensors
    • Ignition coil or spark plug problems
