My 2017 3.5L screw gave me some trouble on Friday while heading up to go snowboarding for the day. The truck was great all the way up I-70 until I turned off onto 40. I got wrench light on the dash and the truck started to loose power and would shift quickly from 7-8 and back. I pulled over and shut the truck off for a few minutes. It started back up fine and drove okay for about 2 minutes and then started shifting back and forth really hard again and then no power and wrench light. I did this a few times and finally the last time let the truck sit for about 5 minutes. Then I started and wrench light was off but then check engine light came on. I put the truck in manual mode and was able to make it up over Berthoud Pass with no issues. Drove fine on the way home, but with the check engine light still on. FordPass indicated all-wheel drive power train failure and a missfire fault. The truck sat all day yesterday and this morning no check engine light and running fine? I have an appointment with the dealer next week, they think it is a throttle body issue? Truck only has 5600 miles on it, hope it is nothing serious, but I must admit not feeling the Ford love at the moment. Anyone else have something similar while in the high country?

 

Really need to know the DTC that was associated with the CEL.

 

So using the Android OBD software the only code I could see is a P0068. The check engine light is currently off and the app shows no trouble. I did not clear anything as I want to be sure that the dealer can see whatever is stored. I am guessing if I had my PC I could see more.

 

P0068

MAP / MAF - Throttle Position Correlation

Description The PCM monitors a vehicle operation rationality check by comparing sensed throttle position to mass airflow readings. This continuous memory DTC sets when during a key ON, engine running (KOER) self-test, the comparison of the throttle position (TP) sensor and MAF sensor readings are not consistent with the calibrated load values.

Possible Causes:

Air leak at any connection or line of the intake air system components before or after the electronic throttle body (ETB)
Leak in the positive crankcase ventilation (PCV) system
TP sensor not seated correctly
Damaged MAF sensor
Damaged TP sensor

Diagnostic Aids:

An intake air system leak at a hose, line or connection of any intake air system or PCV system component may cause this DTC to set.

Diagnose any MAF or TP DTCs first.

If the throttle plate is closed and the LOAD PID is greater than 55%, or with the throttle plate at wide open throttle (WOT) with the LOAD PID less than 30% indicates a concern is present.

 

Thank you for the information. When I called the dealer they said it sounded like the throttle body. I will go take a look for any obvious things like a loose hose or clamp.
