Please house, I need help concerning the WIRING of my ambient air temperature sensor, my AC don't function properly,on diagnosis,code p0073 came out,n unfortunately when we checked mine,the sensor switch and wiring was not there,i bought the car used,though it had bumper accident b4,n a new bumper was fixed nd now my mech does not know how to trace the WIRING, and we need install the sensor n wiring back to bumper

 

Here are the instructions.

You must look for a two wire harness, Blue/White & Brown.

Body shops are notorious for ignoring small broken parts and stuffing them in locations that are hard to find. Hopefully you will not have to remove the bumper.
