[quote=ZAHANMA]I actually had a short in my ambient temp sensor. It was shorted out showing -34F when it was unplugged and should be reading 130F or something like that. Basically there had been a short across and the polarity switched. I pulled my ambient temp sensor, put a wire in there to cause a short. Then i reset the battery drove for a few weeks without a ambient temp sensor, then put the temp sensor back in to test it out. Works just fine.

NOTE: My dash was still showing the correct temperature.


same thing happened to my pickup!! replaced every sensor known to man but the temp sensor cause it threw no code! 400$ later and a tow the mechanic put a 12$ sensor in and it was fixed! temps read -190 * and the ecu was dumping gallons of fuel!!
