Checking wiring and components: Notes
Check the heated oxygen sensor (HO2S) resistance between #3 and #4.
Check signal cable between heated oxygen sensor (HO2S) #4 and control module #A17 (#A17) and power supply between system relay #3 and heated oxygen sensor (HO2S) #3 for an open-circuit according to Open-circuit, permanent faults .
Remedy as necessary.
