04 Mini Cooper S 138,000 mi
Of course just when I need to get a smog ck the light comes on. LOL
I have an EQUUS INNOVA 3160 ABS CanOBD2 Code Reader & Scan Tool and it says.
Post catalyst fuel trim system too lean bank 1
I just replaced the 02 sensor after the cat but the lights still on.
Here is the freeze frame data.
Fuel sys 1 OL
calc load 0
ect 71
STFT B1 0
LTFT 8.5
MAP 28.6
ENG RPM 0
VEH SPEED 0

Any ideas? Thanks for any help.

 

Little more up date.
I checked the exhaust back pressure before the Cat and it is 0psi so the Cat is not plugged up.
But here is a weird one. The temp before the Cat is around 380-450 deg. And after the Cat its only about 140-215 deg.
From what I read if the cat is working it should be hotter after the Cat. as it burns up carbon monoxide and hydrocarbons.
If the Cat is not working shouldn't the temp be the same before and after? Or is this low temp a sign of a bad Cat?

 

With the mileage on your car it could be a sign of a bad cat. Check for an exhaust leak at the post cat flange as well.

Oh, also, I don't believe the 2096 can be cleared by most code readers, even if the problem is fixed.

 

2096 is a "hard" code and it will not clear with any code readers out there.

Take a look at this thread for more information.

And, this is my story about 2096 that never came back on after the "reset". You may want to try that before replacing parts.

 

Volki, thanks for the info. I tried search but some how missed that thread.
Looks like I'm off to the dealer to get a re flash and code clear.
I hate it when I cant fix something my self. LOL.

 

Good luck! I hope that takes care of the problem.
