Bad PCM Symptoms
Powertrain Control Module (PCM) could be the engine control unit can be found on almost all latest vehicle models. Its main function would be to translate the performance of the engine to a language which can be understood by humans along with the drivability status of that particular vehicle. It is very important to every driver to know the many bad PCM symptoms in order to identify them if they arise.
Three bad PCM symptoms that are common;
If the engine light icon becomes visible on the dashboard, there is a possibility that your PCM has detected a problem. The light turns on mostly when the engine sensors or circuits aren’t working while they should. It’s, however, been recorded that the engine light icon can illuminate on the dashboard by mistake. You ought to, therefore, look for expert advice from your mechanic whenever you experience this sign of a negative PCM.
·Misfiring of the Engine
Misfiring of the engine is the most typical bad PCM symptom as a faulty computer can’t run the car to its full capability. The starring of the engine, however, will not have any pattern or frequency and drivers should, therefore, be keen and record any changes in the behavior of the engine.
