Fuel Injector(S)

Disconnect fuel injector harness connector. Measure resistance across injector terminals. Resistance should be as specified. See FUEL INJECTOR RESISTANCE table.

FUEL INJECTOR RESISTANCE

Application (1) Resistance (Ohms)
2.0L (VIN K) 1.6
2.0L Turbo (VIN M) 2.0
2.2L (VIN G) 1.6
2.3L (VIN A & D) 1.9-2.1
2.5L (VIN R & U) 1.6
3.1L (VIN T) 12.0-12.4
3.1L Turbo (VIN V) 12.0-12.4
3.3L (VIN N) (2)
3.8L (VIN C) (2)
5.0L (VIN E) 1.2
5.0L (VIN F) 10.0
5.7L (VIN 7) 1.2
5.7L (VIN 8) 10.0
(1) Injector resistance specification is at 140°F (60°C).
(2) Information 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 INJECTOR BALANCE TEST.
