The engine control module basically controls the intersection of the engine 's necessary ingredients to make energy -- fuel, air and spark. That sounds simple, kind of in the same way an engine itself sounds simple if you break it down into really basic terms.

- What Is The Difference Between An ECM and A PCM?
The most common symptoms of a bad PCM are poor engine performance and a check engine light on your dashboard. You may also notice problems with the transmission, like shifting issues. Poor fuel economy and increased emissions are also quite common. While it’s not common for a PCM to break, it does happen from time to time. Before you jump straight ...
The PCM is the brain of the power delivery unit in your engine. It controls various features, including ignition timing, fuel delivery, emissions, turbo boost pressure, idle speed, throttle control, and so much more. While you might’ve heard of Transmission Control Module(TCM) or an Engine Control Module (ECM), a PCM controls both of those function...
The PCM is most often located in the engine bay near the fuse box or inside the car near the fuse box. It can often also be located under the front windshield behind some covers. There are a few different locations where the manufacturer can place your vehicle’s PCM, but the most common location is in the engine bay. The PCM doesn’t look like anyth...
The PCM is a computer, and computers aren’t cheap to replace. That’s why the average PCM replacement cost is anywhere between $800 and $1,500, depending on the car model and labor costs. Even worse, this is almost all in the cost of the PCM itself. Labor typically only runs between $75 and $100. But if you think you can save yourself $100 and repla...
No. A car can’t run without a PCM. The PCM (Powertrain Control Module) is responsible for monitoring and controlling all the engine’s and transmission operating parameters, including fuel delivery, ignition timing, and emissions controls. Without a PCM, your car won’t start.
Fixing a PCM isn’t something that most people can do. It really depends on the issue and how comfortable you are with computers. If it’s a simple software problem, it could take less than an hour. However, if it’s a hardware issue, it could take several hours or even require replacing the entire PCM.
Testing a PCM is very difficult to do unless you have a lot of experience with these kinds of things. What you can do is test if the PCM is getting voltage and ground with a multimeter, but other than that it’s better to leave it to the pros if you don’t know how to test it.
An ECM, or engine control module, is a computer that controls the engine. A PCM, or powertrain control module, is a computer that controls the transmission and engine in order to optimize fuel economy and power. The two systems are similar, but the ECM focuses specifically on the engine while the PCM regulates both the engine and transmission. Cate...
An electronic control unit (ECU), also known as an electronic control module (ECM), is an embedded system in automotive electronics that controls one or more of the electrical systems or subsystems in a car or other motor vehicle.
A control module is a collection of sensors, actuators and basic control logic that acts as either a regulating device, a state-oriented device or a combination that is operated as a single device.
