The check engine light comes on and stays on when a problem is detected \015\012by the self diagnosis system of your vehicle. Generally, the problem is \015\012in the emissions or something that is affecting the effectiveness of the\015\012 emissions, but other causes can trigger the light to come on, too. To \015\012determine the cause, the vehicle will need to be taken to AutoZone or a \015\012shop that has an OBD2 scanner, or for 1995 and earlier models, an OBD1 \015\012scanner, While a scanner will not give you the magic answer, it will \015\012give you a code that narrows down the problem area.\015\012
\015\012A flashing check engine light is an indication of a severe misfire or \015\012problem that is likely to harm your engine. Immediate diagnosis and \015\012service is needed.\015\012
\015\012Some specific causes for the light to be on are:\015\012
\015\012Gas cap left off, not tightened, not installed correctly, or needs to be replaced\015\012
\015\01202 sensor\015\012
\015\012Engine misfire - error might clear itself after 3 complete warm-up cycles; not restarts, but warm-ups\015\012
\015\012At start up for a bulb check - Should not stay on\015\012
\015\012Problem in the emission system, including clogged exhaust or the catalytic converter not functioning properly\015\012
\015\012Dirty/clogged air filter\015\012
\015\012Dirty MAF sensor\015\012
\015\012There are pages and pages of items that can cause a check engine light \015\012to come on. Having it checked with a scan tool will narrow down the \015\012problem area.
