INSPECTION

PROCEDURE

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

NOTICE:

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

(a) Remove the fuel delivery pipe sub-assembly (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 3 (E2).

(Fuel Pressure Sensor)

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 3 (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.
