Inspection [09/2014 - ]: Procedure
- INSPECT FUEL DELIVERY PIPE SUB-ASSEMBLY (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 2 (E2).TEXT IN ILLUSTRATION
*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 a voltage of 6V or higher 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, etc.
Measure the voltage between terminals.
Standard Voltage
Tester Connection Condition Specified Condition 3 (PR) - 2 (E2) Pressure not applied to fuel pressure sensor Approximately 0.42 to 0.58 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)

(Fuel Pressure Sensor)If the result is not as specified, replace the fuel delivery pipe sub-assembly (fuel pressure sensor).
- Apply 5 V between terminals 1 (VC) and 2 (E2).
