WARNING: This page is about a different variant/trim than selected.
  1. Ignition/Vehicle - Off
  2. Remove the component: B74 Manifold Absolute Pressure Sensor - Leave the electrical connector connected.
  3. Install the special tool: EN-23738-A  Vacuum Pump @ B74 Manifold Absolute Pressure Sensor
  4. Ignition - On / Vehicle - In Service Mode
  5. Use the special tool to achieve a gauge reading between -13 and -21 kPa (-0.13 and -0.21 bar, -3.8 and -6.2 in Hg).

    Verify the scan tool parameter: MAP Sensor=Decreases between 13 and 21 kPa (1.8 and 3.0 PSI)

    • If the parameter does not decrease between 13 and 21 kPa (1.8 and 3.0 PSI) 

      Replace the component: B74 Manifold Absolute Pressure Sensor

    • If the parameter decreases between 13 and 21 kPa (1.8 and 3.0 PSI) 
  6. Use the special tool to achieve a gauge reading between -30 and -38 kPa (-0.3 and -0.38 bar, -8.8 and -11.2 in Hg).

    Verify the scan tool parameter: MAP Sensor=Decreases between 30 and 38 kPa (4.4 and 5.5 PSI)

    • If the parameter does not decrease between 30 and 38 kPa (4.4 and 5.5 PSI) 

      Replace the component: B74 Manifold Absolute Pressure Sensor

    • If the parameter decreases between 30 and 38 kPa (4.4 and 5.5 PSI) 
  7. All OK.
