Testing



2.4L & 2.7L Engines
  1. Using a voltmeter, measure the voltage between terminal 1 (sensor ground) and terminal 4 (sensor output), 2002-2003 vehicles.
  2.  
  3. Using a voltmeter, measure the voltage between terminal 4 (sensor ground) and terminal 1 (sensor output), 2001 vehicles and 2004-2006 vehicles.
  4.  
  5. Specification should be 4-5 volts, with the ignition switch ON.
  6.  
  7. Specification should be 0.8-2.4 volts at idle.
  8.  
  9. If not within specification, replace the sensor.

Operation



This sensor converts the pressure in the intake manifold to voltage signal The ECM judges the condition of the EGR by this signal.

Removal & Installation



  1. Disconnect the negative battery cable.
  2.  
  3. Disconnect the connector from the sensor.
  4.  
  5. Remove the sensor retaining screws.
  6.
