Diagnostic Test

1. Turn ignition switch OFF.
2. Remove EVAP control system pressure sensor with its harness connector. Refer to REMOVAL AND INSTALLATION .

   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 terminals under the following conditions.

   ECM			Applied vacuum kPa (bar, kg/cm2 , psi)	Voltage
   Connector	+	-
   	Terminal	Terminal
   E10	121	148	Not applied	1.8 - 4.8 V
   			-26.7 (-0.267, -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 (- 0.933 bar, - 0.952 kg/cm² , - 13.53 psi) or pressure over 101.3 kPa (1.013 bar, 1.033 kg/cm² , 14.69 psi).

Is the inspection result normal?

YES
