When it comes to problems that can occur with your vehicle, the most troublesome are the ones that occur with your ECM (Engine Control Module). Why? Well, there are several reasons. Firstly, these problems are very difficult to trace and can show up and then disappear at will.

Secondly, these symptoms often trump the mechanic, mainly because the symptoms often appear far from where the actual problem is. Moreover, there are as many as six signs your engine control module is failing.

Lastly, it’s not difficult to understand why ECM problems are so problematic since the ECM is considered your vehicle’s brain, whether you’re driving an average car or a truck. So, why exactly is an ECM considered the automobile’s brain? Let’s find out!

1. It’s In The Name: Engine Control Module

It shouldn’t be so surprising that a device called an engine control module in your car is the brain of your vehicle. Essentially, your car has several electronic control units (ECUs) that are embedded microcontrollers responsible for controlling one or multiple systems in your car.

ECM or Engine Control Module is one of these ECUs and as the name suggests, is responsible for controlling your engine. A microcontroller that controls your car’s engine? That sounds like enough reason to call it your car’s brain.

2. Modern Cars Are More Electronic, Less Mechanical

Quite simply, modern cars are getting more and more electronic and their engines are getting more sophisticated with time. Therefore, the unit responsible for running the sophisticated engine is going to be absolutely crucial.

Your car’s ECM controls the way your vehicle runs, its idle speeds, and fuel injection. Basically, ECM is responsible for your vehicle performance and your fuel efficiency. Essentially, as more and more electronic components are introduced, ECM’s importance only increases.

3. ECM Is at The Intersection of Your Engine’s Energy Making

Fuel, air, and spark are the three necessary ingredients your petrol or diesel engine vehicle needs to make energy. ECM is at the intersection of all this and accomplishes this through a network of sensors that help the ECM ensure that your car’s conditions are always in the optimal range.

So, when something goes wrong, ECM adjusts conditions and if it can’t do that, the car won’t be running properly. That’s when you’ll start noticing the common ECM failure symptoms!
