Checking components and wiring: Notes
Check the resistance of the heated oxygen sensor (HO2S) between terminals #3 and #4.
Check the signal cable between heated oxygen sensor (HO2S) terminal #4 and control module terminal #A18 (#A18). Check the power supply between system relay terminal #3 and heated oxygen sensor (HO2S) terminal #3. Check for an open-circuit.
Remedy as necessary.
