Component Inspection

The purpose of measuring INJ resistance is to find if the open circuit is in the component.

  1. Check INJ
    1. Measure resistance between terminal 1 and 2 of sensor connector (To sensor side)

      Specification: 20°C (68°): 13.8~15.2Ω

    2. Is measure resistance within Specification?

      YES 

      • Substitute with a known-good PCM and check for proper operation. If the problem is corrected, replace PCM and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.

      NO 

      • Substitute with a known-good INJ and check for proper operation. If the problem is corrected, replace INJ and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
        NOTE: The purpose of measuring injector resistance is to find if the open circuit is in the component. Check the continuity between signal line and ground line.
