How do you check a 1997 ford ranger check engine light codes?
There are pages and pages of things that can cause a check engine light. You need to have it checked with a scantool. Then the code can be diagnosed and repaired.
A check engine light means that a malfunction has been detected with the emission control system - if the check engine light does not go out ( sometimes the problem corrects itself and the light goes out ) have the Ranger scanned for trouble codes in order to diagnose and then repair the malfunction
When the check engine light comes on , a malfunction has been detected with the emission control system , if the light stays on steady have the Ranger scanned for any trouble codes to diagnose and then repair the problem ( also if the light flashes on and off continuously with the engine running that indicates a spark plug misfire , scan , diagnose and repair )
