If the truck isn’t making good power I’d say it’s fuel related or boost related
Update, a plug on the wire harness was slightly loose. I’m back in business.. :-)
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, 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...
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...

Sorry I’m just seeing this. Did you ever fix your issue?
Is it behind the cluster on a 2013 ProStar also?
I’ve had FMI 11 SPN 751 before on my 2013. Is the truck up shifting and downshifting ok?
That’s an awesome truck you have there!! I’m loving this positive documented journey with it :cool: 100%
When you re gear, do you have to change out the entire rear or just the ring and pinion? Also does it require an ECM reprogram after?
I had it bumped to 1750.. The clutch is good to 1850. Could I run the engine at 1850tq? Or should I leave it where it’s at with some wiggle room?
