Fuel Pressure Sensor: Inspection

INSPECT FUEL PRESSURE SENSOR
1. 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/cm² )) to the sensor.
