MAP Sensor Functional Inspection 

Test Procedure 

• Procedure
  • Check the atmospheric pressure with a barometer.
  • Turn the vehicle to the ON mode.
  • Confirm the HDS [MAP Sensor (Hi Res)].
  • Start the engine and let it idle.
  • Confirm the HDS [MAP Sensor (Hi Res)].

• Normal Conditions
  • HDS [MAP Sensor (Hi Res)] value is almost the same as the atmospheric pressure before the engine is started, and it is negative pressure after the engine is started.

Results 

• If it is abnormal, there is a problem with the MAP sensor.
