CIRCUIT DESCRIPTION
The Manifold Absolute Pressure (MAP) sensor responds to changes in intake manifold pressure. The PCM supplies a 5 volt reference and a ground for the MAP sensor. The MAP sensor provides a signal to the PCM relative to the pressure changes in the manifold. With low manifold absolute pressure (high vacuum such as during idle or deceleration), the PCM should detect a low MAP sensor signal voltage. With high manifold absolute pressure (low vacuum such as key ON, engine OFF or wide-open throttle), the PCM should detect a high MAP sensor signal voltage. The PCM monitors the MAP signals for voltages outside the normal range of the MAP sensor. If the PCM detects a MAP sensor voltage that is excessively low, DTC P0107 will set.

CONDITIONS FOR RUNNING THE DTC
^ No TP sensor DTCs are set.
^ Throttle position is more than 10 percent when engine speed is more than 1000 RPM.
^ Throttle position is more than 0 percent when engine speed is less than 1000 RPM.

CONDITIONS FOR SETTING THE DTC
^ The MAP sensor signal voltage is less than 0.07 volt.
^ The condition exists for less than 1 second.

ACTION TAKEN WHEN THE DTC SETS
^ The PCM illuminates the Malfunction Indicator Lamp (MIL) during the second consecutive trip in which the diagnostic test runs and fails.
^ The PCM stores the conditions present when the DTC set as Freeze Frame and Fail Records data.

CONDITIONS FOR CLEARING THE MIL/DTC
^ The PCM will turn the MIL OFF after the third consecutive trip in which the diagnostic runs and passes.
^ The history DTC will clear after 40 consecutive warm-up cycles have occurred without a malfunction.
^ The DTC can be cleared by using the scan tool Clear DTC Information function.
