Checking The Components And Wiring
Check the resistance of the heated oxygen sensor (HO2S) between terminals #1 and #2.
Check the signal cable between heated oxygen sensor (HO2S) terminal #2 and control module terminal #A6 (#A6).
Check the power supply between system relay terminal #3 and heated oxygen sensor (HO2S) terminal #1. Check for an open-circuit.
Remedy as necessary.
