Pathfinder LE 4WD V6-3.3L (VG33E) (1997)
Absolute Pressure Sensor: Testing and Inspection
COMPONENT INSPECTION
1. Remove absolute pressure sensor with its harness connector connected.
2. Remove hose from absolute pressure sensor.
3. Turn ignition switch "ON" and check output voltage between terminal (2) and engine ground.
The voltage should be 3.2 to 4.8 V.
4. Use pump to apply vacuum of -26.7 kPa (-200 mm Hg, -7.87 inHg, -3.87 psi) to absolute pressure sensor as shown in figure and check the output
voltage.
The voltage should be 1.0 to 1.4V lower than the value measured in step 3.
CAUTION: Always calibrate the vacuum pump gauge when using it.
5. If NG, replace absolute pressure sensor
