Skewed Sensor Test

WARNING: This page is about a different car, the 2007 Saturn Outlook. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF, remove the vacuum source from the MAP sensor.
  2. Ignition ON, observe and record the scan tool MAP sensor pressure parameter. This is the first MAP sensor reading.
  3. With the J 23738-A  or J 35555  apply 5 in Hg (17 kPa) of vacuum to the MAP sensor. See Special Tools . Observe and record the scan tool MAP sensor pressure parameter. This is the second MAP sensor reading.
  4. Subtract the second MAP sensor reading from the first MAP sensor reading. Verify that the vacuum decrease is within 1 in Hg (4 kPa) of the applied vacuum.
    • If the vacuum decrease is not within the specified range, replace the MAP sensor.
  5. With the J 23738-A  or J 35555  apply 10 in Hg (34 kPa) of vacuum to the MAP sensor. See Special Tools . Observe and record the scan tool MAP sensor pressure parameter. This is the third MAP sensor reading.
  6. Substract the third MAP sensor reading from the first MAP sensor reading. Verify that the vacuum decrease is within 1 in Hg (4 kPa) of the applied vacuum.
    • If the vacuum decrease is not within the specified range, replace the MAP sensor.
