Comments  |  Add Comment

Possible causes

  • Faulty Mass Air Flow (MAF) sensor
  • 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
  • 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

    Possible symptoms

  • Engine Light ON (or Service Engine Soon Warning Light)
  • Lack/Loss of power
  • Engine rough idle
  • P0068 2003 Ford F150 Description

    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.
