Also to know is, what would cause my ECM to go bad?
Corrosion and moisture Corrosion or damage due to moisture is one of the main reasons for ECM failure. Corrosion can enter the ECM through the wiring harness and moisture can enter by a failure in the seals in the ECM itself. This happens over a period of time (5 to 10 years) due to the ECMs exposure to the elements.
Also, what does the ECM control? The ECM, or electronic control module, is the computer responsible for controlling all of the engine management functions. It is the central control unit of most vehicles and controls a variety of functions, such as electrical system power distribution, emissions, ignition, and fuel systems.
Accordingly, can I drive my car with a bad ECM?
First off, don't confuse replacing an ECM with repairing one. The end result might be the same -- you can drive your car again, after all -- but engine control modules and units do sometimes go bad, and they aren't really designed to be repaired -- at least, not by the owner or by an average mechanic.
How much does it cost to replace an ECM in a car?
The average cost for an engine control module (ECM) replacement is between $904 and $991. Labor costs are estimated between $79 and $101 while parts are priced between $825 and $890. Estimate does not include taxes and fees.
