Hello all. First post on the forum.
I've got a '05 outback XT 2.5L 4 cyl. manual transmission with 75,000 miles on it. Earlier this year the check engine light came on and I had the following code pulled:
P2096 Post Catalyst Fuel Trim System Too Lean Bank 1
My tech found it was the O2 sensors and I ended up having to replace all of them before the check engine light would stop coming on.
It's been fine for about 3 months but now the check engine light is back on, with the same diagnostic code. I had my guy check it out and all the O2 sensors are working fine and behaving properly. He suggested I take it to the dealership because it might be an issue with the electronic control unit. I know this can be a pricey fix if it is the issue.
Any ideas on what may be happening that would cause this code to happen if the O2 sensors are ok?
Thanks for any info you can provide!
