How Much Does It Cost To Replace A PCM In A Car??

Without this system working on top form, you can end up with a number of car problems.

The cost of replacing your powertrain control module will be between $450 and $1,630.

For labor, you can expect to pay between $45 and $125.

Parts should cost you $400-$1,500.

What are the symptoms of a bad powertrain control module?

A bad or failing ECM may produce any of the following 5 symptoms to alert the driver of a potential problem.

  • Check Engine Light Turns On. An illuminated Check Engine Light is one possible symptom of a problem with the ECM.
  • Engine Stalling or Misfiring.
  • Engine Performance Issues.
  • Car Not Starting.
  • Poor Fuel Economy.

Can you drive a car with a bad PCM?

A failing PCM disrupts the functions of many components along with the engine. As the module becomes unable to read the sensors correctly, the car won’t be able to give its best performance. The state of affairs will cause the check engine and a few other error lights to come on.

What causes a PCM to fail?

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). Thermal stress and vibration can form microcracks in circuit boards (which are repairable).

Will a bad PCM throw a code?

Continuing to run a vehicle with a bad PCM could cause further damage. Because the PCM controls the emissions of your car, a failed emissions test or the presence of oddly-colored or foul smelling exhaust may be a sign that your PCM is going bad. A malfunctioning PCM will activate dashboard error lights.

Can a bad PCM cause transmission problems?

For example, poor performance or unexplained drops in fuel economy or efficiency are often related to onboard car computer problems, or faulty ECU issues. A damaged ECU can cause problems when shifting gears in an automatic transmission, or cause sudden jerking or stopping that’s similar to transmission problems.

What happens if my PCM goes bad?

Misfiring of the Engine. Misfiring of the engine is the most common 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.

What does a powertrain control module do in a car?

The TCU or Transmission control module takes inputs from the engine sensors or TCU to change the gears for the optimum engine performance and fuel efficiency of your cars. The PCM gets inputs from the sensors which are spread around the car and which gives information related to Engine management and performance.

Can you reflash a used PCM?

You don’t have to re flash for the car to run. However you can’t use a pcm from a car that had factory security. If neither has the security,you can just swap them out and the car will run with no problem.
