Changed both O2 sensors on Porsche Cayenne (V6) in Bank 2 and still getting following Error Codes: P0160 (Bank 2 Sensor 2)/P0159 (Bank 2 Sensor 2)...Could the new BOSCH O2 sensor have failed ALREADY (Error came on about 2-3 hrs after installation)? Any help would be greatly appreciated!!!

P0159 Oxygen Sensor Aging After TWC, Bank 2 - Above Limit

Possible fault cause

- Oxygen sensor faulty

- DME control module faulty

P0160 Oxygen Sensor After TWC, Bank 2 – Open Circuit

Possible fault cause

- Open circuit in the signal wire and/or ground wire of oxygen sensor

- Loose contact in connector

- Open circuit in B+ and/or negative line of the oxygen sensor heating

- Oxygen sensor faulty (heating resistance too high)

- DME control module faulty

Check the wiring.

If it all tests ok then perhaps try a DME reprogram.

DME = Digital Motor Electronics - Porsche's engine management system, the Bosch "Motronic" system, that controls both fuel injection and ignition functions. (see the Glossary link at the top right of the page)
