To find it, you'll need to do some searching specific to your van's year and engine. Here's how to approach this:
1. Find your engine code: This is usually found on a sticker under the hood or in your owner's manual. It will be an alphanumeric code (e.g., 5.7L Hemi, 6.7L Cummins).
2. Consult a repair manual: A repair manual specific to your year and model Ram 2500 will have diagrams showing the location of all sensors, including Bank 1 Sensor 2 (often labeled as O2 sensor). You can find these manuals online (e.g., Chilton, Haynes) or at auto parts stores.
3. Use online resources: Search online using your specific vehicle's year, model, and engine code along with "Bank 1 Sensor 2 location." You might find images or forum discussions from other owners who have had similar questions. However, be cautious; always double-check information found online against a reputable source like a repair manual.
4. Look at the exhaust manifold: Bank 1 Sensor 2 is usually located *after* the catalytic converter on the exhaust manifold of the engine's "Bank 1" (the side of the engine that typically contains cylinder #1). It's a threaded oxygen sensor usually wired into the vehicle's harness. However, the exact position will vary.
Important Note: If you're not comfortable working on your vehicle, it's best to take it to a qualified mechanic to have the sensor located and replaced. Incorrectly diagnosing or attempting to replace the sensor could lead to further damage.
