Fuel Injectors & Circuit: 1.9L

  1. Turn ignition off. Disconnect fuel injector connector. Using a Digital Volt-Ohmmeter (DVOM), check resistance across fuel injector needle lift sensor terminals.
  2. Resistance should be 80-100. If resistance is zero ohms, check for short circuit in wiring harness. If wiring harness is okay, replace fuel injector(s).
  3. If resistance is as specified, check fuel injector connector wiring harness for open or short circuit to ECM. Repair circuit as necessary. If circuit is okay, replace ECM.
