It provides very limited info but is nice for resetting CEL if nothing else.

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

I received my OBD2 Bluetooth adapter yesterday from China ($15 shipped) and used it with the free "Torque" App on my Android phone. It reported that I have a "pending" fault code P1123, which I believe could be an over-rich situation reported by the MAF? Is there anything I should do at this point? Maybe clean the MAF? I recently installed the K&N cold air set up (I know, I know) and have read that this could be the culprit, although who knows, the pending fault may have been there before installation. Is it possible that when the computer figures out the new K&N air/fuel mixture, this "pending" fault will disappear? Can you clear a "pending" fault?

Hey, Trapperdog. How do you like the ODB2 bt adapter? Are they all pretty much commodity items now? One is as good as the other. I noticed a $15 Chinese ODB2 bt adapter on ebay. Just go for it?

I went for it and mine works pretty good. It provides very limited info but is nice for resetting CEL if nothing else.

POST 4 / ORIGINAL POSTEROriginal post

Well my pending P1123 code is now a CEL logged fault. I reset it with my China OBD BT. I'll be interested to see how long before it's a pending or logged fault again.

POST 5Original post

Could be a dirty MAF. Wouldn't hurt to check it & clean it if it looks like it needs it.

Do not clean with anything but MAF Cleaner or you may end up replacing it. http://napaonline.com/Catalog/Catalo...110_0069315352
