What does the powertrain control module control?
Consequently, what are the symptoms of a bad powertrain control module?
Symptoms of a Bad or Failing Engine Control Module (ECM)
- Check Engine Light Turns On.
- Engine Stalling or Misfiring.
- Engine Performance Issues.
- Car Not Starting.
- Poor Fuel Economy.
Furthermore, where is the powertrain control module? Common Locations for a PCM, ECM, or TCM To help you out, here are some examples of where the ECM is located on a few different makes and models: 2001 Dodge Ram 1500 SLT – The engine control module or, in this case, the powertrain control module (PCM) is located in the engine compartment, on right side of firewall.
Also know, what does the powertrain control module do?
The PCM is an especially powerful computer that manages or monitors the engine's ignition system, fuel injection, emission systems, mechanical positioning of the rotating assembly, exhaust system, transmission, and any other functions related to the operation of the engine and transmission.
What causes powertrain control module failure?
PCMs typically fail for one of two reasons: voltage overloads (often due to a short in a solenoid or actuator circuit) or environmental factors (corrosion, thermal stress or vibration). If water gets inside a PCM, it can short circuits and set up irreversible corrosion that ruins electronic connections.
