Nissan Rogue (T33) 2021-Present Service Manual: Evap Control System Pressure Sensor

Component Inspection

CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR

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 (bar, kg/cm2, psi)]	Voltage
   Connector	+	−
   	Terminal
   E21	129	155	Not applied	0.5 – 4.6 V
   			−26.7 (−0.3, −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 (−0.9 bar, −0.952 kg/cm², −13.53 psi) or pressure over 101.3 kPa (1.0 bar, 1.033 kg/cm², 14.69 psi).

Is the inspection result normal?
