2015-2017 – F-150 – Intermittent Loss Of Throttle Response – Multiple Warning Indicators And/Or Multiple Diagnostic Trouble Codes (DTCs)
Some 2015-2017 F-150 vehicles may experience 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.
Inspect and repair damaged circuits before properly routing the harness.
If the harness is properly routed, proceed with normal diagnostics.
