|How is the P0068 2003 FORD F150 code repair?

Start by checking the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.

|P0068 2003 FORD F150 code tech notes

Drive vehicle and exercise throttle and TP sensor in all gears. A TPNS PID less than 4.82% (0.24 volt) with a LOAD PID greater than 55% or a TPB V PID greater than 49.06% (2.44 volts) with a LOAD PID less than 30% indicates a hard fault

|What is the cost to diagnose the P0068 2003 FORD F150 code

Labor: 1.0

The cost to diagnose the P0068 2003 FORD F150 code is 1.0 hour of labor. The auto repair's diagnosis time and labor rates vary by location, vehicle's make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.

|When is the P0068 2003 FORD F150 code detected?

The Powertrain Control Module (PCM) monitors operation rationality check by comparing sensed throttle position to mass air flow readings

|What are P0068 2003 FORD F150 code possible symptoms?

  • Engine Light ON (or Service Engine Soon Warning Light)
  • Lack/Loss of power
  • Engine rough idle

|What is P0068 2003 FORD F150 code meaning?

The Powertrain Control Module (PCM) monitors a vehicle operation rationality check by comparing Throttle Position (TP) to Mass Air Flow (MAF) readings. If, during a self-test, the comparison of the TP sensor and MAF sensor readings are not consistent with the calibrated load values, the test fails and a diagnostic trouble code is stored in continuous memory.
