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.

   ECM			Condition [Applied vacuum kPa (kg/cm, psi)]	Voltage
   Connector	+	-
   	Terminal
   E16	131	158	Not applied	0.5 - 4.6 V
   			-26.7 (-0.272, -3.87)	2.1 to 2.5 V lower than above value

   CAUTION:

   • Always calibrate the vacuum pump gauge when using it.
   • Never 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).
