COMMON RAIL - INSPECTION

1. INSPECT COMMON RAIL ASSEMBLY

Resistance inspection (Fuel pressure sensor)

Common Rail - Inspection. 2AD-FHV FUEL. Lexus IS250 IS220d GSE20 ALE20

Using an ohmmeter, measure the resistance between the terminals.

  • HINT:
  • Perform the inspection with no fuel pressure applied.
  • Standard resistance:
  • TerminalsResistance
    5 (PR) - 4 (E2)16.4 kΩ or less
    2 (PR2) - 3 (E2S)16.4 kΩ or less
    6 (VC) - 5 (PR)3 kΩ or less
    1 (VCS) - 2 (PR2)3 kΩ or less

If the result is not as specified, replace the common rail assembly.


Resistance inspection (Pressure discharge valve)

Common Rail - Inspection. 2AD-FHV FUEL. Lexus IS250 IS220d GSE20 ALE20

Using an ohmmeter, measure the resistance between the terminals.

  • Standard resistance:
  • TerminalsConditionResistance
    1 - 220°C (68°F)0.85 to 1.05 Ω
  • HINT:
  • The temperature indicated in "Condition" refers to the temperature of the pressure discharge valve.

If the result is not as specified, replace the common rail assembly.
