The check engine light (service engine soon) comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, the problem is in the emissions or something that is affecting the effectiveness of the emissions, but other causes can trigger the light to come on, too. To determine the cause, the vehicle will need to be taken to AutoZone or a shop that has an OBD2 scanner, or for 1995 and earlier models, an OBD1 scanner, While a scanner will not give you the magic answer, it will give you a code that narrows down the problem area.
It is possible, but usually fuses fail for a reason
Burned out bulb?
It could be a 5.0L 305 CID. or a 5.7L 350 CID engine.
A trained ear could here them while the engine is running. The only way to know for sure is to tear the engine down and check them with a mike.
Have vehicle scanned to determine problem and recover codes Could be a bad coolant temperature sensor
I'm having the same problem. Check your fuse, should be a 20 Amp fuse number 3 I think, also check the bulbs they are number 921.
That could be a # of things. To know for sure you MUST scan the engine with a engine scanner to find the problem. NO OTHER WAY.
Excess fuel could be one reason. The check engine light should be illuminated. Check the codes and re-post results.
