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.

(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.
