Manifold Pressure/Vacuum Sensor: Testing and Inspection
Manifold Absolute Pressure Sensor
A scan tool displays manifold pressure in kilopascals (kPa) and MAP sensor signal voltage. Low pressure (high vacuum) displays a low voltage while a
high pressure (low vacuum) displays a high voltage.
Circuit Problems
A failure in the MAP sensor circuit should set a DTC P0107 or P0108 and using the applicable table will lead to the cause of the problem. A DTC P0108
may be set if misfire or a rough or unstable idle exists. A DTC P0106 will set for a MAP sensor that intermittently sends a zero voltage signal to the
PCM. The MAP Sensor Output Check located under Computers and Control Systems / Procedures / Diagnsotic Tables can also be used to check
the MAP sensor. See: Computers and Control Systems/Testing and Inspection
