CHECK ENGINE LIGHT STAYS ON – BUT THERE’S NO NOTICEABLE PROBLEMS
Does your check engine light stay on? Need a Check Engine Light Diagnosis for Check Engine Light Codes?
If the Check Engine Light stays on when you’re driving but there’s no noticeable driving or performance problems, it usually means that there’s a permanent fault in the emission control system.
When your check engine light stays on, the computer that controls the emission system usually has a backup program that runs while the fault is present.
These backup programs are often referred to as “limp home” mode programs.
When your check engine light stays on, you should get the vehicle serviced as soon as possible, but in most cases, the vehicle will continue to operate, though you run a risk of it dying or not starting.
