      HINT: 

      • Standard atmospheric pressure is approximately 101 kPa (abs) (14.65 psi (abs)).
      • For every 100 m (328 ft.) increase in altitude, atmospheric pressure drops by approximately 1 kPa (0.15 psi). This varies depending on the weather.
    6. Compare the values of Atmospheric Pressure and Boost Pressure Sensor with the normal atmospheric pressure in the table.

      Result

      Result Proceed to
      Difference between (difference between value of Boost Pressure Sensor and normal atmospheric pressure) and (difference between value of Atmospheric Pressure and normal atmospheric pressure) is 4 kPa (0.58 psi) or higher A
      Other than above B

      HINT: 

      • Use the table below for reference only.
      • In Example 1, as the pressure difference is 4 kPa (0.58 psi) or higher, proceed to the next step.
      • In Example 2, as the pressure difference is less than 4 kPa (0.58 psi), replace the ECM.
