Component Inspection

1. Turn ignition switch OFF.
2. Remove EVAP control system pressure sensor with its harness connector connected from EVAP canister.

   Always replace O-ring with a new one. 

3. Install a vacuum pump to EVAP control system pressure sensor.
4. Turn ignition switch ON and check output voltage between ECM harness connector and ground under the following conditions.
   TERMINALS VOLTAGE REFERENCE
   
   

   ECM		Ground	Condition [Applied vacuum kPa (kg/cm2 , psi)]	Voltage
   Connector	Terminal
   M107	102	Ground	Not applied	1.8 - 4.8V
   			-26.7 (-0.272, -3.87)	2.1 to 2.5V lower than above value

   CAUTION:

   • Always calibrate the vacuum pump gauge when using it.
   • Do not apply below -93.3 kPa (-0.952 kg/cm² , -13.53 psi) or pressure over 101.3 kPa (1.033 kg/ cm² , 14.69 psi).

Is the inspection result normal? 

YES: INSPECTION END

NO: Replace EVAP control system pressure sensor
