H36 - Check HO2S Heater Resistance

- Suspect sensors disconnected.

- Inspect sensor end of the connector for damaged or pushed out pins, moisture, contamination, etc. Service as necessary.

- Measure the resistance between VPWR circuit and HO2S heater signal at the HO2S connectors.

- Are both heater resistance readings between 2.0 and 30.0 ohms?

YES -- Go to H37. H37 - Check For Shorts In the HO2S Heater Harness Circuit

NO -- Resistance out of specification. REPLACE HO2S(s) RECONNECT all components. Rerun quick test. Diagnostic Subroutines (DSR) - Extracting Codes
