Hello. I was hoping maybe someone could clue me in. I have a 99 Civic LX 5spd with 186k. Check engine light has been coming on lately and the code reads "P0113 IAT sensor 1 circuit high input". I clear the code and it will come back on usually within 50 miles of driving. When the check engine light first started coming on it always seemed to be when I had a quarter of tank of gas or less but now it comes on at random times. The IAT sensor is the small plastic sensor that goes below the air filter on the filter holder on top of throttle body, correct? I switched out that sensor with one from a 96 Civic DX that was running fine with no check engine lights but the light still comes on in my car with that one too. Any thoughts? Thank you for your time.
