When do you have a bad Powertrain Control Module?

If you are getting codes for a faulty oxygen sensor, for example, and you have replaced all the related components but the check engine light remains illuminated, then you may have a bad PCM. The ECU is responsible for many areas of the vehicle that control whether or not the vehicle starts.

Is there a possible Battery Control Module fault?

Possible Battery Control Module Fault?? I have been through topics on this which have been very useful. However I am concerned that I do not want to throw money at parts I don’t need. With a new full battery I get the consumables message up after about an hour driving.

What does red mean on Battery Control Module?

When not in UB mode, the message in red is a battery symbol and visit workshop. However I did notice that after I took it for a drive and shut down, it only fell off to about 12.3v after a couple minutes. When I started it up again, it was only 12.5v and didn’t spike the voltage up to 13.8-14v until I gave it some throttle and let off.

Is it the alternator or the Battery Control Module?

Bottom line I believe it is normally the alternator, but its not a cheap replacement I am afraid. You may also end up changing the main battery. In my case, the smaller 2nd battery was low but charged up again and holds it power now. Hope this helps.

What are the symptoms of a bad engine control module?

1. Check Engine Light Turns On 2. Engine Stalling or Misfiring 3. Engine Performance Issues 4. Car Not Starting 5. Poor Fuel Economy The engine control module (ECM), also commonly referred to as the engine control unit (ECU) or powertrain control module (PCM), is one of the most important components found on virtually all modern vehicles.

What is the name of the engine control module?

The engine control module (ECM), also commonly referred to as the engine control unit (ECU) or powertrain control module (PCM), is one of the most important components found on virtually all modern vehicles.

How is the powertrain control module related to the emission system?

This shows how the emission system is directly related to the powertrain control module, and how a faulty powertrain control module can negatively affect the emissions. The main interaction that drivers will have with the powertrain control module is when the check engine light comes on your dashboard.

How to reset the engine control module with no hassle?

Why does my car not accelerate when I press the gas pedal?

This sensor sends a reference voltage to your power-train control module, which uses that to determine ignition timing and fuel trims. If the power-train control module is not detecting the proper signal from the throttle position sensor, the engine may not accelerate properly.

What’s the name of the sensor on the accelerator?

Modern vehicles are equipped with a lot of sensors and computers to manage basic car controls automatically and precisely. That helps in better gas mileage, smoother, comfortable and a safe drive. Almost every modern car now has a sensor called the TPS and an accelerator pedal position sensor.
