disclaimer read yes Problem with my 1998 pontiac grand am Mileage = 112,000 Engine size = 3.1 v6 dash lights = check engine light codes = p0113 iat sensor work done prior = none work done to repair = none tech = jk question = where is the iat sensor. Intake air temperature sensor. I nee to fix code to pass emmisions, thanks.
JK: That sensor is located on the air intake tube between the air filter box and the throttle body. It is a 2-wire connector. Most likely is either unplugged or one of the wires is broken right at the connector. A little tug in each wire will tell you if the wire is broke, the insulation will stretch, and then break. Back
