Lexus ES: Inspection

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 (fuel delivery pipe with sensor assembly) 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 (fuel delivery pipe with sensor assembly) 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.
