H32 - Check HO2S Heater Resistance

- Suspect sensor 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 Heater SIG. circuit at the HO2S connector.

- Is the resistance between 2.0 and 30.0 ohms?

YES -- Go to H33. H33 - Check For Short to GND In the HO2S Heater Harness Circuit

NO -- REPLACE HO2S. RECONNECT all components. Rerun quick test. Diagnostic Subroutines (DSR) - Extracting Codes
