Ford Repair Questions? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose) I prefer working afternoon till just after midnight.
Can you tell me more about this chip, what it does, how it is installed?
Once you did the battery reset, how soon do the lights come back on?
Beside the lights is the vehicle operating any different?
Thanks, ***** ***** chip is doing is confusing the IAT reading to the computer so the computer will change the air fuel ratio by adding more fuel. The check engine light has come on because this chip is bad or was installed wrong or it has given the computer an IAT reading that it realizes is no way possible. The advance trac warning has possibly come on because the vehicle is getting a wrong IAT and MAF reading so it thinks your applying throttle but your not moving so the computer thinks there is an issue with the ABS wheel speed sensor readings.
My suggestion is to have it scanned at a parts store or shop to see which codes are stored. Then remove the chip and reset the codes to see if they return. This will tell you if the chip is to blame or not for these codes.
