Hello I have a 2013 ProStar with the MF13 (2012 build date).. Getting a code for ambient air temp sensor SPN 171 FMI 3.. I hear they’re 2 sensors on the truck. I found one under the front of the truck near the horn. Where is the other sensor located? Thanks.

Update, the second sensor is located on the wire harness that runs along side the left frame rail between the back of the cab and the drive axle wrapped in tape..

Ok another update.. I changed the sensor and the truck is still throwing a code for the sensor. I’m at a loss. Any help is appreciated.

Update, a plug on the wire harness was slightly loose. I’m back in business..
