i hooked up a code reader to figure out my service light and why im getting bad mpg.
the reader says my air intake temp is -40 degrees i replaced the senser and it still says the same i traced the wires as far as i could into the harness and they appear to be fine
has any one else had this problem or any suggestions? ive ran out of ideas


02 eco 5spd sunfire

Maybe the sensor is bad? Would be my guess.

i tried 4 different ones 3 from a junk yard and i bought 1 brand new and it still dose it. The only thing i can think of is the wireing harness got messed up when i rolled my 2000 sunfire
6 times last year in august then i bought my 96 and used all my same parts and ive had this problem ever since i switched everything and i did everything as i did before.......?

its fine. -40 is some cold ass air, you get bad mpg cuz its dumping in fuel and advancing timing. just like a resistor mod. ebay would be proud.

seriously though, check for continuity all through that circuit, something is off somewhere
