  1. Ignition ON, observe the MAP sensor pressure parameter and compare the reading on the scan tool to the barometric pressure table. Refer to .
    • If the MAP sensor pressure is not within the range specified for your altitude, refer to DTC P0107 or P0108 .
  2. Start the engine, observe the MAP Sensor parameter. The reading should be between 32-42 kPa.
