7GR-FKS FUEL  FUEL PRESSURE SENSOR(for High Pressure)  INSPECTION  


PROCEDURE

Hide 23860 1.INSPECT FUEL DELIVERY PIPE WITH SENSOR ASSEMBLY LH

NOTICE:
·

Do not remove the fuel pressure sensor from the fuel delivery pipe sub-assembly LH.

·

If the fuel pressure sensor is removed, replace a new fuel delivery pipe with sensor assembly LH.



a.

Check the fuel pressure sensor output voltage.

(Fuel Pressure Sensor)
*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) and 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 according to the value(s) in the table below.

Standard Voltage:
Tester Connection Condition Specified Condition
3 (PR) - 2 (E2) Pressure not applied to fuel pressure sensor 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 with sensor assembly LH).
