I recently encountered the check engine code P2096 on my vehicle. Can anyone explain what this code indicates or suggest possible causes and solutions? Any insights would be appreciated. Thank you in advance.

This code usually points to an issue with the post-catalytic converter fuel trim being too lean. It could be due to a faulty oxygen sensor, a vacuum leak, or even a problem with the fuel system. To really nail down the cause, it’s best to have a mechanic run a diagnostic. Based on my experience, getting it checked sooner rather than later can save you from more costly repairs down the road.

Post Catalyst Fuel Trim System Too Lean Bank 1" is what P2096 stands for. It signifies that a lean fuel-to-air mixture is detected by the Powertrain Control Module after the catalytic converter. I would advise you to examine the oxygen sensors at Bank 1 and look for exhaust leaks.
Since an O2 sensor generates electricity, a drop to 0 volts could indicate a malfunctioning sensor or damaged PCM circuitry. Considering that the automobile is relatively new, I believe the problem lies in the sensor. However, if it reappears later, don’t be shocked; there might be another issue.
