1.INSPECT FUEL PRESSURE SENSOR
Check the fuel pressure sensor output voltage.
| *a | Component without harness connected
(Fuel Pressure Sensor) |
| *b | Voltage Applied between Terminals |
Apply 5 V between terminals 1 (VC) and 2 (E2).
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) or 2 (E2).
If a stable power supply is not available, connect 4 nickel-metal hydride batteries (1.2 V each) or equivalent in series.
| *a | Component without harness connected
(Fuel Pressure Sensor) |
Measure the voltage according to the value(s) in the table below.
| 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.
