INSPECTION
PROCEDURE
1. INSPECT FUEL PRESSURE SENSOR (FUEL DELIVERY PIPE WITH SENSOR ASSEMBLY)
NOTICE:
- Do not remove the fuel pressure sensor from the fuel delivery pipe with sensor assembly.
- If the fuel pressure sensor is removed, replace the fuel pressure sensor
(fuel delivery pipe with sensor assembly) with a new one.
(a) Check the fuel pressure sensor output voltage.
| (1) Apply 5 V between terminals 1 (VC) and 3 (E2).
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) or 3 (E2).
HINT: If a stable power supply is not available, connect 4 nickel-metal hydride batteries (1.2 V each) or equivalent in series. |

*b | Voltage Applied between Terminals | | |
| (2) Measure the voltage according to the value(s) in the table below.
Standard Voltage: |
Tester Connection | Condition |
Specified Condition | |
2 (PFL) - 3 (E2) |
Pressure not applied to fuel pressure sensor |
Approximately 0.57 to 0.95 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 (fuel delivery pipe with sensor assembly). |
