)UNIT INSPECTION
1. Fuel pressure sensor check
(1) Output voltage check
(a) Measure the voltage between the terminals.
Voltage
| Inspection terminals |
Inspection conditions |
Standard value |
|---|---|---|
| 2(VOUT) - 1(GND) |
Apply 5 V voltage between the terminals 3 (VCC) and 1 (GND). |
Approx. 0.5 V |
Captions in illustration
| *1 |
Connector not connected (Fuel pressure sensor) |
CAUTION:
·Wrong connection of the inspection terminals may damage the fuel pressure sensor. Pay special attention to the connection work.
·Do not apply voltage of 6 V or higher between the terminals 3 (VCC) and 1 (GND).
·Do not apply voltage of 6 V or higher between the terminals 3 (VCC) and 1 (GND).
NOTE:
If a stabilized power source is not available, use nickel hydride batteries (1.2 V × 4) etc.
