Check HO2S

WARNING: This page is about a different car, the 2021 Hyundai Kona. However, it is still accessible from the selected car via links, so may be relevant.
  1. Visually/physically inspect the following parts:
    • Ensure that the HO2S is securely installed. (Pigtail and wiring harness not making contact with the exhaust pipe)
    • Check for corrosion on terminals and terminal tension (at the HO2S and at the PCM)
    • Front HO2S for silicon contamination. This contamination will be indicated by a white powdery coating on the portion of the sensor exposed to the exhaust stream and this will result in a but false (high) voltage signal
    • Fuel, engine coolant or oil contamination
    • Use of improper sealant
  2. Was a problem found in any of the above areas?

    YES 

    NO 

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