99 ram, abs and brake light went on and speedo stopped working. Replaced sensor and seem to be back in business except for check engine light. How do I shut it off? Tried to disconnect battery but didnt work. Do I need to buy some type of code reader? thanks ed

 

If you don't actually have an engine problem it will go out on it's own after a certain number of shutoffs.

Do a search for "key trick" to find a way to get the code, as well as clear the light. I don't remember how to do it 'cause I have a scanner. Any OBD2 (OBDII) scanner will read and clear the engine codes. Harbor Freight carries scanners for stoopid cheap. I think I paid $30 or something for mine.

 

thanks, been meaning to get a scanner for a while anyway. ed

 

Turn key to run position three times, leave at run position and watch code readouts in the odometer window.

 

no speedo codes on 99

 

Correct.

Either get your hands on a scan tool of some sort and check out what code it is/clear it. Or depending on what time of code was set (and nothing is actually wrong) it will clear itself after so many shut offs/starts. I think the number is 3 times but i could be wrong.

 

The key trick does not work with 99's. You need a scan tool. In my opinion, if you have an auto parts store nearby, and aren't a mechanic, don't spend money on a scan tool. Yes, they're handy, but it takes nothing to use the auto part store's loaner tool.

On trying to pull the batts, did you disconnect both negatives for 5 min. or so? That should "always" reset the check engine light. If it's still there, I'd say there is something else it's trying to tell you.
