Condition
Downstream oxygen sensor errors P013B00 (005C35, Bank 1) and P013D00 (005C3B, Bank 2) - ‘Slow Response
– Rich to Lean’ of the 2.9 liter bi-turbo V6 engine for the Cayenne S and Cayenne S Coupé occurring under
the following operating conditions:
•
•
•
•
Low engine speed (1200 – 1500 rpm)
Calculated engine load at approximately one-third (25 – 35%)
Engine temperature approaching or at operating temperature (50 – 100°C)
Low vehicle mileage (0 – 500 miles)
Technical Background
An increased diagnostic sensitivity occurring under specific engine operating conditions, as described above, can
cause the aforementioned faults to set the engine’s malfunction indicator lamp (MIL). In cases seen thus far 		
exhibiting these faults under the described operating conditions, changing the engine oil and filter is proving to 		
cease the faults’ occurrences. This matter is under investigation.
