The check engine light in my B2300 truck stays on, but the truck seems to run fine. Trying to find out why.?

Get an OBD-II reader or go to Autozone and pull the codes.





Reset the CEL and if it comes back, you know you have an issue. If not, then nothing to worry about.

Probably a sensor is bad, maybe an oxygen sensor. Go to autozone and they will run a code scanner on your truck and tell you what is making the check engine light come on. Then you can buy the part from them and you are good to go...

Maybe you are not screwing the gas cap on tight enough after refueling. Try turning it till it clicks.
Reply:The first thing you should do is to make sure your gas cap


is on correctly. At the dealership I work at, most check


engine lights are the gas cap not on correctly or the gas


cap has gone bad.
