  • Faulty Manifold Absolute Pressure sensor
  • Manifold Absolute Pressure harness is open or shorted
  • Manifold Absolute Pressure sensor circuit poor electrical connection
  • Faulty Engine Control Module (ECM)
  • Tech notes

    Sensor operating voltage is greater than 5.0 volts (VREF), as a result it failed above maximum allowable calibrated parameter.
    VREF should be less than 6.0 volts.

    When is the code detected?

    The Engine Control Module (ECM) has detected a performance fault with the anifold Absolute Pressure (MAP) sensor

    Possible symptoms

  • Engine Light ON (or Service Engine Soon Warning Light)
  • Engine rough idle
  • Engine hesitation
  • P0108 2001 Ford F150 Description

    The Manifold Absolute Pressure (MAP) sensor provides instantaneous manifold pressure information to the engine's Engine Control Module (ECM). The data is used to calculate air density and determine the engine's air mass flow rate, which in turn determines the required fuel metering for optimum combustion. A fuel-injected engine may alternately use a Mass Air Flow (MAF) sensor to detect the intake airflow.
