  • Large vacuum leak
  • Leaking air duct system
  • Mass Air Flow (MAF) poor electrical connection
  • Manifold Absolute Pressure (MAP) poor electrical connection
  • Faulty Manifold Absolute Pressure (MAP) sensor
  • TP sensor not seated properly
  • Faulty Throttle Position (TP) sensor

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

When is the Code Detected?

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

What are Code Possible Symptoms?

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

What Does the P0068 2002 Ford F150 Code Mean?

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.
