Component Testing

    IMPORTANT: The engine coolant temperature (ECT) sensor must be between 10-32°C (50-90°F) in order for an accurate measurement.
  1. Measure for 11-14 ohms of resistance between the terminals of the fuel injector.
    • If the resistance is not within the specified range, replace the fuel injector.
