ECM/PCM Processor

44 brands affected · Generic SAE J2012 description.

Key terms: Control module: a small computer that runs one part of the car · SAE J2012: the standard generic code list · Powertrain: engine, transmission and emissions

1What it means in plain English

The engine control module's processor has reported an internal fault, so engine management may be unreliable.

2Common causes

  1. Internal engine control module fault
  2. Low or unstable battery voltage
  3. Power or ground connection problem
  4. Water or corrosion damage
  5. Electrical interference from a faulty component

3Can I drive?

Serious · drive with care

If the engine runs normally, drive carefully to a workshop for diagnosis. If it runs badly, stalls, or will not start, have the car towed.

This page gives general information. It is not professional advice. For a definite diagnosis and a repair quote, ask a qualified mechanic to inspect the car.
