Where is the oxygen sensor bank one 2 located on a 2000 Chevy silverado?

On a 2000 Chevy Silverado, the location of the Bank 1, Sensor 2 oxygen sensor varies slightly depending on the engine (4.3L, 4.8L, 5.3L, 5.7L, 6.0L, etc.). There's no single definitive answer.

To find it, you'll need to:

1. Consult your vehicle's repair manual: This is the most reliable source. The manual will have diagrams showing the exact location of all sensors.

2. Use a repair database: Online repair databases like AllDataDIY or Mitchell1 (subscription required) provide detailed diagrams and specifications for your specific vehicle.

3. Visually inspect the exhaust manifold and catalytic converter: Bank 1 refers to the bank of cylinders containing cylinder #1. Sensor 2 is downstream of the catalytic converter. Look for a wire harness leading to a sensor located in the exhaust pipe after the catalytic converter on the driver's side (Bank 1). It will likely be screwed into the exhaust pipe.

Important Safety Note: The exhaust system gets extremely hot. Allow it to cool completely before attempting any work near the oxygen sensors.

Without knowing your exact engine size, I cannot give you a precise location. Using the resources above is crucial for accurate identification.
