Tell-Tale Signs of a Faulty Ford Engine Control Module
Your Ford Engine Control Module or ECM is the brains of your car's entire engine system. Without it, your vehicle will be paralyzed and dysfunctional. Since the ECM is just like any other car component in terms of make and material, it is naturally prone to damage and normal wear. There are various elements that can contribute to its eventual degradation. There is, however, something you can do to stop the problem from worsening, and that is to act upon it the moment the first symptom shows. Below are some of the tell-tale signs that you must watch out for to prevent ECM problems from going downhill.
When your engine suddenly refuses to start even though it has been in good performance recently, there must be something wrong with your engine. Just to make sure, try to shut it off and restart it. If nothing happens, then the starter might have shorted out your Ford engine control module. This sometimes happens as a result of the fuel solenoids corroding. When the solenoids corrode faster than the ECM, the former shorts out the latter until they both become dysfunctional.
Voltage problems and faulty codes
Getting voltage problems is one sure indicator that something is wrong with your vehicle. It's just a matter of identifying what the problem is and coming up with a viable solution. Sometimes, voltage problems are caused by overriding the sensor that controls the voltage going to the engine control module. This bypassing also results to faulty codes, among other problematic results. Bypassing the sensor may take place when replacing the engine starter with a wrong model.
Your vehicle is equipped with engine lights that are supposed to go on and off depending on the status and condition of the engine. If your car's engine light remains on forever without them ever blinking, there is a good chance that your ECM is not working properly. This may be a result of excessive heat, corrosion, moisture, and vibration over a period of five to ten years. When your ECM experiences any of this through the wiring harness, then your ECM is doomed to fail.
Sudden jerking and stopping
When your car suddenly halts in the middle of nowhere, there may be something wrong with your Ford engine control module. Sometimes, the ECM's power supply has either too much voltage or not enough. This obviously poses a problem which causes your ECM to misbehave.
Burnt out injector driver circuit
Check your injector driver circuit regularly to see if it is still working well. If it's not, then it is probably due to a shorted fuel injector. The mere brakes in the internal wiring of your harness can cause a short on the engine control module, thus rendering it useless. To prevent this from happening, do not expose your ECM to natural elements as much as possible. When they are left hanging out there in the open, they are more prone to corrosion, moisture, and wear and tear.
