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.
