Checking components and wiring: Notes
CAUTION:
Do not apply rust solvent spray or grease to the heated oxygen sensor (HO2S) connector.
Check the signal cable (+) between heated oxygen sensor (HO2S) terminal #1 and control module terminal #A43 (#A43). Check the signal cable (-) between heated oxygen sensor (HO2S) terminal #5 control module terminal #A44 (#A44). Check for a short-circuit to each other.
Check the power supply to heated oxygen sensor (HO2S) terminal #3. Check the signal cable between heated oxygen sensor (HO2S) terminal #4 and control module terminal #A17 (#A17). Check for a short-circuit to the other wiring for the heated oxygen sensor (HO2S).
Try a new heated oxygen sensor (HO2S) if the wiring is OK.
Remedy as necessary.
