P2096 on 2013-2023 MINI GP — Post Catalyst Fuel Trim System Too Lean (Bank 1)
1 vehicles · 1 makes · $800-$3,000 repair
Most Reported On
P2096 is an OBD-II diagnostic trouble code meaning “Post Catalyst Fuel Trim System Too Lean (Bank 1).” This code means the engine computer detected that the fuel mixture downstream of the catalytic converter on Bank 1 is too lean (too much air relative to fuel) based on the rear oxygen sensor. The computer uses the downstream sensor to fine-tune fuel trim after the catalyst. A persistently lean reading suggests unmetered air entering the exhaust or a fueling/sensor issue. While not immediately dangerous, prolonged lean conditions can affect emissions and, in some cases, contribute to engine running problems. This code is most commonly reported on 2013-2023 MINI GP, with repair costs ranging from $800 to $3,000.

FAQ
What does P2096 mean?
P2096 stands for "Post Catalyst Fuel Trim System Too Lean (Bank 1)." This code means the engine computer detected that the fuel mixture downstream of the catalytic converter on Bank 1 is too lean (too much air relative to fuel) based on the rear oxygen sensor. The computer uses the downstream sensor to fine-tune fuel trim after the catalyst. A persistently lean reading suggests unmetered air entering the exhaust or a fueling/sensor issue. While not immediately dangerous, prolonged lean conditions can affect emissions and, in some cases, contribute to engine running problems.
What are the most common causes of P2096?
The most common causes of P2096 are: Exhaust leak before or near the downstream oxygen sensor, Vacuum leak causing a lean intake condition, Faulty downstream (post-catalyst) oxygen sensor, Faulty upstream oxygen sensor skewing trims, Low fuel pressure or weak fuel delivery, Dirty mass airflow sensor, Intake manifold or gasket leak. The specific cause varies by vehicle.
