Check your fuses in your engine bay. When mine was on (along with a few others) it was the "ENG CONT" Fuse
yeah but you also had idle issues (as did I) but he says everything is running fine Check your lights, inc break lights. do a search also because i seem to rememeber when I raised this before, someone said something about break lights and something possibly shorting out causing the low error light? can't remember but yeah, do a search and its all there.
settle down kids As ugame first said. check every bulb for operation. If there's 1 bulb not working then you'll have this warning light come up.
