Service Engine code P2097

quickboat

Thanks for the response Jordo.
I am running stock air boxes and the silicone tube inserts. I checked the fittings and they are tight at the air box and the TB. The small tubes that go to the valve covers look good too. The engine has never been run hard enough to get hot let alone real hot, so that code must be bogus. I am running K&N filters, could it be oil on the MAF sensors? If so how can I clean them?

PS Did you look at my data logs? I cleared the codes and am driving now without codes yet.

Jordo!

A bogus code points to an electrical problem tho... you shouldn't just get random codes like that.

Can you export the datafile to excel or put them into tables?

The data file came out as a txt file. It is up a coupe of posts, did you see it? The code came back after about 80miles. I called the Stealership, i guess I have to get the stock tubes back on. CRAP!

Jordo!

It's hard to follow displayed as text instead of in a table, but it looks like you are getting pretty divergent readings from the MAF sensors.

I'm not sure about the different sets of fuel trim data - the first grouping look nominal but the ones listed later are high for one bank

It's possible the MAF sensors need to be cleaned -- pick up some CRC MAF cleaner spray and just spray them down.

That still doesn't explain the weird DTC's... I think after trying to clean the MAF, if no change, going to the dealership is your best option.

I can tell you that the tubes and filters are NOT radically changing things enough to cause sensor problems.

Over oiling could be an issue on the MAF, but if you spray it clean and nothing changes, there's something else going on.

Yay, first post here for me!

Just had a similar issue on my '14 Base Sport Coupe. Took it to the dealer and they said that there was an O2 sensor part number change around the time when my car was built (early Jan, 2014) and my car had three correct O2 sensors installed and one wrong sensor installed from the factory. (Old part number...) My car tripped the P2099 code which is the same as yours but the other bank. I have 2600 miles on it. Bone stock.

Wonder if you have the same problem I do? The new part is backordered at the moment.

Good luck.

The new part number is backorded? Did you get the car back while waiting? Since it sounds like I have the same issue and need a car.
Somethng funny the service rep said when I told him the car had K&N filters. " I wonder if the oiled filter could have damaged the O2 sensor."
I said , "Uh maybe got oil on the MAF but I didn't see any with visual inspection and certianly didn't effect the O2 sensor..."

Looks like this service dept might be trouble...

I've got the car back and was told it was okay to drive until the part comes in although since it is my second car and not my DD, I have not put many miles on it with the service engine soon light on. Also haven't beat on it in case the cat temps are out of whack.

You really need to simply hand over the keys next time and not say anything about your mods if you don't take the car back to stock before going to the dealer for service.
