Fuel Injector Coil Test

WARNING: This page is about a different car, the 2018 Buick Encore. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
  • The resistance test must be performed at the fuel injector or mis-diagnosis will occur.
  • The DMM and test leads must be calibrated to 0 Ω in order to prevent mis-diagnosis.
  1. Disconnect the appropriate Q17 Fuel Injector.
  2. Test for 1.35 - 1.65 Ω at 20°C (68°F) between the control + circuit terminal 2 and the control - circuit terminal 1 at the Q17 Fuel Injector.
    • If not between 1.35 - 1.65 Ω 

      Replace the Q17 Fuel Injector.

    • Go to next step: If between 1.35 - 1.65 Ω 
  3. Test for infinite resistance between each terminal at the Q17 Fuel Injector and the Q17 Fuel Injector housing/case.
    • If less than infinite resistance 

      Replace the Q17 Fuel Injector.

    • Go to next step: If infinite resistance 
  4. All OK. Perform the Fuel Injector Balance Test.
