2007 Vue Redline P0113
I have a 2007 Vue Redline with a P0113 code. I've replaced the sensor and it keeps coming back. I clear the faults on the ECU and within seconds the code comes back. I've tested the voltage at the sensor and I'm getting voltage so I know its not a broken or grounded/shorted out wire. What else can be causing this?

A little more info, I'm getting 3.14v across the IAT sensor.

Re: 2007 Vue Redline P0113
The voltage across the leads with the sensor unplugged bounces between 4.99 and 5V When the sensor is plugged it started at 3.14 and slowly dropped as the engine warmed up. When I clear the ECU I hear the throttle body opening and closing, I'm not sure if that's normal or not on this vehicle when clearing the codes? The P0113 code returns almost immediately after clearing the code without even having to start the vehicle.

Sorry for the multiple updates. Tried to work on this in between work calls.

Re: 2007 Vue Redline P0113
Are you reading the sensor output voltage to chassis ground? Find the wire at the input to the ECU and read the voltage there. Chances are it is not reading correctly at the ECU connector, meaning the problem is somewhere between the sensor and the ECU.
