General Maintenance & Repairs - IAT code

Hi everyone,
I have a lq4 with the green and blue pcm in a 99 s-10 extreme. The Intake air temperature sensor reads -39, whether its hooked up, not hooked up or shorted out. Any suggestions? Also my gauge cluster wont turn on until i hook my scan tool up.

Thanks in advance!

I know someone could pitch in on this.

Mine read -39 when it went bad. Caused the car to stutter and misfire. Get a replacement from autozone they are brass and much better

I would post in the conversions section....lots of people read that section that are sued to dealing with these things.

Appreciate the replies, what vehicle is the sensor from? also why do my gauges turn on when i hook my scan tool up? Could a mod move this?

Bump!

bought a brass IAT from O'reilly auto parts and im still reading -39
