Checking components and wiring
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 #A70 (#B10). Check the power supply between system relay terminal #5 and heated oxygen sensor (HO2S) terminal #3. Check for an open-circuit.
Remedy as necessary.
