INSPECTION
PROCEDURE
1. INSPECT NO. 2 FUEL PRESSURE SENSOR
(a) Check the No. 2 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 No. 2 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. | .png) | | *a | Component without harness connected (No. 2 Fuel Pressure Sensor) | | *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 No. 2 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 No. 2 fuel pressure sensor. |  | | *a | Component without harness connected (No. 2 Fuel Pressure Sensor) | | |
