Checking the components and wiring
Visually check that the rear heated oxygen sensors (HO2S) have not been mounted in the wrong bank on banks 1 and 2.
Read off the voltage of the probe on the rear heated oxygen sensor (HO2S) for bank 1.
Read off the voltage of the probe on the rear heated oxygen sensor (HO2S) for bank 2.
HINT: If the voltage is constantly close to 0 V on one bank and 1 V on the other bank, or vice-versa, the rear heated oxygen sensors (HO2S) have been switched.
Try new heated oxygen sensors (HO2S) if the above fault-tracing does not remedy the fault.
Remedy as necessary.
