Most car owners face problems when their car keys stop working. It can get frustrating, especially if you are running late and do not have a spare key.

It is the engine control module or ECM that makes the extraction of power possible with more efficiency. The ECM plays a significant role in keeping vehicle emissions lowered. It monitors the vehicle engine and constantly tunes the output to the driver’s demand. For example, ECM works to pass the power or economize cruise fuel.

As a result, even if the check engine light appears, it goes unnoticed because your vehicle seems to drive well. A bright check engine light can notify you whenever the ECM detects an issue in the system.
