Injector Inspection

WARNING: This page is about a different variant/trim than selected.
  1. Turn "OFF" the ignition switch.
  2. Disconnect injector connector.
  3. Measure the resistance between High terminal and Low terminal of the injector (component side).

    Specification: 

    Temperature (°C/°F) Coil Resistance (Ω)
    Normal Parameter At 20°C (68°F) 1.30 ~ 1.44
  4. Is the measured resistance within specification?

    YES 

    • Check for poor connection between ECM and component: backed out terminal, improper mating, broken locks or poor terminal to wire connection. Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.

    NO 

    • Substitute with a known-good injector and check for proper operation. If the problem is corrected, replace the injector and then go to ""Verification of Vehicle Repair"" procedure.
