Ok, I have an '03 Cavalier with manual trans. No engine mods at all.

My CEL has come on and give me this...P0113 Intake Air Temperature (IAT) Sensor Circuit High Voltage
Sometimes it studders and misses because of this, and feels like it has a power loss. Only thing is, its not like that all the time.

I have replaced the IAT sensor and erased the code. After a few hours, the CEL came back on, and its doing the same stuff.

Any help anyone?

Check the wires really well. Make sure they have not gotten pulled on at the connector.

possibly the sensor connector, had problem with coolant temp sensor, after replacing sensor twice and ripping apart all the wiring in middle of winter that's what it came to, the connector. not sure if iat sensor would have similar problem

Thanks guys, Ill look over it somemore.

Ok, I checked voltage at the plug today. Sometimes it was there, sometimes it wasnt. Check voltage at the wire and it was solid. So I plug is bad. Im going to pick one up in a few days. Hopefully it will solve my problems.
