Fuel Pressure Sensor/Switch: Testing and Inspection

INSPECTION

1. INSPECT FUEL PRESSURE SENSOR (for Port Injection)




a. Check the fuel pressure sensor output voltage.
1. Apply 5 V between terminals 3 (VC) and 1 (E2).
2. Measure the voltage between terminals 2 (PR) and 1 (E2).

Standard voltage: Approximately 0.5 V

HINT: The above voltage is output when pressure is not applied (0 kPa (0 kgf/sq.cm)) to the sensor.
