INSPECTION

PROCEDURE

1. INSPECT FUEL DELIVERY PIPE SUB-ASSEMBLY LH (FUEL PRESSURE SENSOR)

NOTICE:

  • Do not remove the fuel pressure sensor from the fuel delivery pipe sub-assembly LH.
  • If a fuel pressure sensor is removed, replace the fuel delivery pipe sub-assembly LH with a new one.

(a) Remove the fuel delivery pipe sub-assembly LH (See page (b) Check the fuel pressure sensor output voltage. ).

(b) Check the fuel pressure sensor output voltage.

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

*b

Voltage applied between terminals

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, use 4 1.2 V nickel-metal hydride batteries or equivalent.

(2) Measure the voltage between terminals.

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. Output voltage = (0.08 x Voltage applied to terminals) to (0.12 x Voltage applied to terminals)

If the result is not as specified, replace the fuel delivery pipe sub-assembly LH.

(c) Install the fuel delivery pipe sub-assembly LH (See page Installation ).
