PCM – Powertrain Control Module
Ridgeways Auto Repair in Lovettsville, Virginia PCM replacement.
A PCM? What’s that?
Typically buried under other engine components, the PCM is a small box that acts as the brains of the vehicle. It is essentially a small computer that controls the engine, transmission, emission, communication, and several other systems essential to the function of the vehicle. Diagnosing a bad PCM can be tricky, but we have experts up or the task.
What Causes the PCM to Fail?
- Voltage overloads (usually due to a short in a solenoid or the actuator circuit). If the shorted solenoid or actuator isn’t found and repaired, the voltage overload it creates may damage the replacement PCM, too.
- Another cause could be an environmental factor (corrosion, thermal stress or vibration).
