      Faulty Engine Control Unit (ECU) Symptoms – Diagnosis and Repair Solutions

      Symptoms of a Faulty Engine Control Unit – How to Recognize ECU Failure?

      Engine control unit issues are often mistaken for other faults. No start, loss of communication with the ECU, limp mode or reduced engine power can all seem like ECU failure, but in many cases the real cause lies elsewhere – such as electrical wiring problems, injector faults or power supply issues.
