check engine and battery lights

[carlosc]

my car has the check engine light on and sometimes the battery turn on too, last week i put a new battery and yesterday check the electrical system and everything is fine, what can causing that??

guessing at what CEL lights mean is pretty bad to do, and anyone that does it is rather low on the how to fix crap poll (mechanics that do this) get the codes ran at autozone to findout whats wrong and go from there.

update: the service engine and battery lights is because my TPS is damage, and thats why my rev down a little when i reverse, the battery turn on because the sensor has a low voltage , the code was P1125

The tps is pretty easy to replace
