Hey CARYN HORTON,
As I said in my previous message if you would like to check the wiring for this sensor the instructions are below.
You will need a multi-meter to perform these tests.
Disconnect battery negative cable
Disconnect the ambient air temp sensor (after bumper removal)
Access and unbolt body control module (fuse panel underneath drivers side dash)
Disconnect connector C6 shown in second picture.
Check continuity from ambient air sensor connector plug to body control module plug for the two wires shown in wiring diagram below.
Also with both plugs disconnected check resistance between each pin of the ambient air temp sensor and a know good ground. Then switch multi-meter to voltage and do the same check. This ensures you don't have any shorts to ground/positive.
As you can see this is fairly involved and in the interest of time you may choose just to replace the sensor and see how you go.
Don't hesitate if you have any further questions.
Regards, Joe
