Inspection [10/2014 - ]: Procedure

INSPECT FUEL DELIVERY PIPE (FUEL PRESSURE SENSOR)

NOTE:

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 (fuel pressure sensor) with a new one.

Check the fuel pressure sensor output voltage.

Apply 5 V between terminals 1 (VC) and 3 (E2).

*a	Component without harness connected (Fuel Pressure Sensor)
*b	Voltage applied between terminals

NOTE:

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.

Measure the voltage between terminals.

Standard Voltage

Tester Connection	Condition	Specified Condition
2 (PFL) - 3 (E2)	Pressure not applied to fuel pressure sensor	Approximately 0.6 to 0.9 V

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