mvan231 Posted May 27, 2019 Report Share Posted May 27, 2019 I just got a 2016 Edge this weekend and while driving it for >2 hours I had no issues. Now all of a sudden, I see a P2096 code for Post Catalyst Fuel System Trim Too Lean Bank 1. Any ideas? Only thing I did was fill up at a gasoline station then a while after, I saw this code come up.

WWWPerfA_ZN0W Posted May 28, 2019 Report Share Posted May 28, 2019 I don't see anything specifically for the Edge, but in the case of 2013-14 MYs (Focus, Fusion, Escape, MKZ), the issue was oil migration from the VVT solenoids thru the engine wiring harness to the catalyst monitor. The fix is to replace the solenoids, wiring harness, and CMS. If that is not the case, the 3.5L engines have a recalibration fix, might look into that here as well. Did you have any starting issues after fillup? That is usually a purge valve issue on other engines in the Ford family. Quote Link to comment Share on other sites More sharing options...

I did not have any issues starting it after fill up. I did just recently replace the purge valve assembly on my fusion that was having issues with starting after fill up. But that was a P1450 code. I'm thinking since I just bought this vehicle, and it's still covered under warranty, I may take it in. I wasn't sure if something like this would be covered under the Powertrain warranty, but seems it should. Quote Link to comment Share on other sites More sharing options...
mvan231 Posted May 29, 2019 Author Report Share Posted May 29, 2019 Oddly enough, the MIL/CEL is now off. Not sure if it was some bad fuel I picked up along my travels and enough key cycles have passed for it to clear itself out or what happened, but at least it's off for now.

mvan231 Posted June 3, 2019 Author Report Share Posted June 3, 2019 Unfortunately, the code is back. I'm seeing values between 0.1V and 0.9V for the downstream sensor. The upstream sensor only reads out A/F ratio and current. Current readings seem to fluctuate between 0.4A and -0.3A. Not it sure if this could mean the catalytic converter is going bad? I saw some other code pop up as pending. It was P013E which I saw online is a delayed response from the downstream sensor.
