Skewed Sensor Test

WARNING: This page is about a different car, the 2009 GMC Sierra, 2009 GMC Cab & Chassis Sierra, 2009 Chevrolet Silverado, and 2009 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.
  1. Using the following steps and referencing the table below will determine if the MAP sensor is skewed.
  2. Ignition ON, engine OFF, observe the MAP sensor scan tool parameter.
  3. Use the observed MAP Sensor Scan Tool parameter that is closest to a value that is indicated in the first column.
  4. Using the J 23738-A  or the J 35555  to apply 5 in Hg of vacuum to the MAP sensor, the parameter in the first column should decrease by 17 kPa. The acceptable range is indicated in the second column.
  5. Using the J 23738-A  or the J 35555  to apply 10 in Hg of vacuum to the MAP sensor, the parameter in the first column should decrease by 34 kPa. The acceptable range is indicated in the third column.
