NR Series FUEL  FUEL PRESSURE SENSOR  INSPECTION  


PROCEDURE

Hide 23814B 1.INSPECT FUEL PRESSURE SENSOR (FUEL DELIVERY PIPE)

NOTICE:
·

Do not remove the fuel pressure sensor from the fuel delivery pipe.

·

If the fuel pressure sensor is removed, replace the fuel pressure sensor (fuel delivery pipe) with a new one.



a.

Check the fuel pressure sensor (fuel delivery pipe) output voltage.

(Fuel Pressure Sensor (Fuel Delivery Pipe))
*b Voltage Applied between Terminals


Apply 5 V between terminals 1 (VC) and 2 (E2).

NOTICE:
·

Be careful when connecting the leads as the fuel pressure sensor may be damaged if the leads are connected to the wrong terminals.

·

Do not apply more than 6 V to terminals 1 (VC) or 2 (E2).



HINT:

If a stable power supply is not available, connect 4 nickel-metal hydride batteries (1.2 V each) or equivalent in series.

Measure the voltage between terminals.

Standard Voltage:
Tester Connection Condition Specified Condition
3 (PR) - 2 (E2) Pressure not applied to fuel pressure sensor (fuel delivery pipe) Approximately 0.4 to 0.6 V*


*: The output voltage changes depending on the voltage applied to the terminals.

If the result is not as specified, replace the fuel pressure sensor (fuel delivery pipe).
