Read evidence and context

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.

Oh, by the way, when I recently replaced my cats, I replaced all four O2 sensors, just because I felt like wasting $$.

Can you use Torque to plot the four O2 sensor voltage when engine is idling and fully warmed up?

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.

7 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

OK, most of you have probably seen my thread regarding cat-related CEL, that I thought was resolved. Got a CEL today. Is this related to the same issue as previously? (see link in my sig below). Code: .

POST 2Original post

Quotes source post: 11696444

The code is complaining about an O2 sensor. I forgot which one though. I think it's bank1 postcat but not sure. Can you use Torque to plot the four O2 sensor voltage when engine is idling and fully warmed up?

POST 3 / ORIGINAL POSTEROriginal post

Hmmm... I suck at the Torque app. Last time I thought I was graphing data, turns out I was graphing background noise. Do you know of any good online instructions? Oh, by the way, when I recently replaced my cats, I replaced all four O2 sensors, just because I felt like wasting $$.

POST 4Original post

I dunno about online instructions but the PIDs in questions are called: O2 volts bank 1 sensor 1 O2 volts bank 1 sensor 2 O2 volts bank 2 sensor 1 O2 volts bank 2 sensor 2 Also good time to check the "Test Results" now that you have run the cats and new sensors for some time.

POST 5 / ORIGINAL POSTEROriginal post

OK, when I get a chance, I'll take a crack at trying graphing again. For now, I just cleared the code, so I'll see if it comes back. Thanks for the PIDs. There's a long list to choose from, so this is a big help. . The Test Results all are fine. I refreshed it several times just to make sure. .

POST 6Original post

Good luck. Clearing it may work for this specific code since it could be a DME software issue. There was a TSB to update the s/w but not sure if it applies to your VIN though.

POST 7 / ORIGINAL POSTEROriginal post

Thx. I'll revive the thread if the code comes back.

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