Manifold Absolute Pressure Sensor

Operation



Specific to:

Honda CR-V 2007-2008

The Manifold Absolute Pressure (MAP) sensor senses manifold absolute pressure (vacuum) and converts it into electrical signals. The MAP sensor outputs low signal voltage at high-vacuum (idling) and high signal voltage at low-vacuum (throttle valve wide open). The Powertrain Control Module (PCM) compares a predetermined MAP value at a given throttle position and manifold absolute pressure to the output voltage value of the MAP sensor. If the MAP sensor output has lower voltage than expected, the PCM detects a malfunction and stores a DTC.

Testing



Specific to:

Honda CR-V 2007-2008

  1. Connect the Honda Diagnostics System (HDS), or equivalent scan tool, to the Data Link Connector (DLC) located under the driver's side of the dashboard.
  2.  
  3. Turn the ignition switch ON .
  4.  
  5. Check the MAP SENSOR in the DATA LIST.
  6.  
  7. If the voltage is not as specified, inspect the connectors and wiring harness.
  8.  
  9. If no faults are found, replace the sensor.
