2017 F-Super Duty – Intermittent Loss Of Throttle Response – Multiple Warning Indicators And/Or Multiple Diagnostic Trouble Codes (DTC)
Some 2017 F-Super Duty vehicles built on or before 28-Aug-2017, may exhibit an intermittent loss of throttle pedal response, illuminated wrench, hill descent, airbag, anti-lock brake system (ABS) and/or advanced trac warning indicators and/or P2122, P2123, P2124, P2125, P2127, P2128, and/or P2138 DTCs.
This may be caused by the Accelerator Pedal Position (APP) sensor 14A005 harness being improperly routed behind the brake booster to brake pedal bracket.
If the harness is improperly routed, loosen the bracket to free the harness, refer to Workshop Manual (WSM), section 206-06 and inspect for any damaged circuits.
If the harness is properly routed, proceed with normal diagnostics.
