Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Suspected cause

if it comes back, swap the sensors side to side one pair at a time, to see if the code switches to the other side (probably a bad sensor), or stays on the same side (probably a bad cat).

also, you can get a wireless (bluetooth or wifi) adaptor and use Torque (or the equivalent) to graph the gauges and monitor them.

Leading evidence: 'cat)' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'cat)' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Use torque (or the equivalent)' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

2005 TT S Cab... Check engine light on, fault code said O2 Sensor bank 2.. Which one is this and what part number do I need.. Thanks..

POST 2Original post

There are two O2 sensors pre and post cat. I think this diagram may be correct for your car (997) and it shows the two sensors 30 and 31 with part numbers http://www.autoatlanta.com/porsche-p...section=202-01

POST 3Original post

Try this one too http://www.autoatlanta.com/porsche-parts/hardparts.php?dir=997T-07-09&section=202-00

POST 4Original post

It is best to post the error code(s). This way one can consult the references to know which bank and which sensor on which bank is being indicated.

POST 5 / ORIGINAL POSTEROriginal post

Cleared the code.. Will,run again.. Also it is a 996 2005 TT S

POST 6Original post

Quotes source post: 12999428

Ok. I have the 996 OBD2 reference. (I grabbed one for use with my 2003 996 Turbo.)

POST 7Original post

if it comes back, swap the sensors side to side one pair at a time, to see if the code switches to the other side (probably a bad sensor), or stays on the same side (probably a bad cat).

POST 8Original post

also, you can get a wireless (bluetooth or wifi) adaptor and use Torque (or the equivalent) to graph the gauges and monitor them. It should be pretty easy to tell which one is the culprit or if you indeed have a cat going bad.

POST 9 / ORIGINAL POSTEROriginal post

Have the durametric and will drive it till code reappears.

This is a source reference. Confirm exact model applicability in the original material.
