I had a thermostat go bad and my "check engine" light came on. The truck is now fixed but the light remains on. How do I get rid of it? Thanks

Ok, How do I clear the code? Also, How do I get a code? Thanks!

Turn the key to the 'on' position, then off, then on, then off, then on and leave it in the on position. At no point during this proceedure, turn the engine on. (that is turn it to the 'on' position 3 times in 3 seconds or so, leaving it in the 'on' position to read the codes)

The codes will appear in the odometer and end with P-Done. Write them down and bring them back here.

To clear codes, you could go to autozone and they may clear them, or the dealer, or you can buy something to do it. But..... after a few engine starts with everything running well (nothing to set a code), the light will turn off.

Ok here's the code! 0514

Looked it up in my repair manual and it said code P0514 is Battery temp sensor rationality! Should of looked at the book to begin with! Sorry to have bothered you! I got it!

P0514 refers to a problem with the battery temperature sensor circuit. I'm not familiar with the diagnostics for that one, but I've seen it quite often on here regarding 3rd gen trucks. I believe the code sets in error, and there may be new software to correct it.

Bothered? No way. I think the dealer can upgrade the software to get rid of that bothersome code. Back to my

Well, I do appreciate it! I bought 2 new batteries for cheap insurence. The truck has 86k on it and I belive the batteries are original. So better to be safe then sorry! Plus, the idiot light went away so, all is good! Now back to my--->
