Fuel Injector(s)

Disconnect fuel injector harness connector. Measure resistance across injector terminals at each injector. Resistance should be as specified. See INJECTOR RESISTANCE SPECIFICATIONS .

INJECTOR RESISTANCE SPECIFICATIONS ⁽¹⁾

Application

Ohms

4.9L (VIN B)

⁽²⁾

⁽¹⁾	Injector resistance specification is at 140°F (60°C).

⁽²⁾	Information is not available from manufacturer. Solenoid should have resistance; however, infinite resistance indicates an open injector winding.

NOTE: If injectors are dirty, they should be cleaned using approved injector cleaning procedure before performing PFI INJECTOR BALANCE TEST.
