Codes p0113 and p1111

[DTP RACER]

I have been getting these two codes for about 2 months now on my 1999 Coupe. The car has a Halltech cold air kit, larger MAF ends, both of which have been on the car for over 2 years. I have replaced the IAT sensor as well as the wires leading to the sensor (as far as I could trace/reach them), the codes will go away for approx. 1 day then come back. Don't want to go to the dealership as they will probably say it has something to do with the cold air kit.

Any help would be greatly appreciated.

Frank,

Welcome to the Corvette Action Center. Here are the codes you're receiving from http://corvetteactioncenter.com/kb/question.php?qstId=242 :

P0113 Intake Air Temp (IAT) Sensor Circuit High Voltage

P1111 Intake Air Temperature (IAT) Sensor Circuit Intermittent High Voltage

I was going to say that it probably has something to do with the Cold Air Intake as well. Have you talked to Jim Hall at Halltech about this?

HI there,
The only way to correctly diagnose this condition is to see the real time data from the IAT to the PCM.
This would require a scan tool.
