Can I keep driving?
Usually drivable; have it fixed at the first opportunity.
First step
A typical diagnostic sequence used by mechanics, provided here for educational reference only. Diagnostic work should be performed by a qualified mechanic with the appropriate tools and training. 1. Inspect the exhaust visually from cat to rear sensor, look for soot streaks at flanges or cracks indicating a leak 2. Hold a piece of paper near suspect joints with the engine running, exhaust pulses will move it visibly if there's a leak 3. Read live data from both oxygen sensors, healthy front sensor switches rapidly between rich/lean, rear sensor sits steady around 0.6-0.8V on a healthy cat 4. Check the rear sensor connector for damage 5. If exhaust is sealed and front sensor is healthy, the rear sensor or cat is likely the next suspect
P2096 is a Powertrain (engine, transmission, fuel system) fault code. It indicates: Post Catalyst Fuel Trim System Too Lean (Bank 1) . This is a standardised OBD-II code. The technical definition is the same regardless of the make or model of vehicle, although specific causes and symptoms can vary between vehicles.
This information follows the generic OBD-II definition and does not replace a vehicle-specific diagnosis. The severity rating is rule-based; an authorised diagnostic reading is required for a definitive answer.
