Where is oxygen sensor bank 1 2 located on a 2005 Chevrolet truck?

The exact location of the oxygen sensor bank 1, sensor 2 on a 2005 Chevrolet truck depends on the engine (e.g., 4.3L, 4.8L, 5.3L, 6.0L, etc.). There's no single answer.

To find it:

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 resources like AllDataDIY, Mitchell 1, or others (often subscription-based) provide detailed diagrams and repair information specific to your vehicle's year, make, model, and engine.

3. Look online for forums: Search online forums specific to your 2005 Chevrolet truck (mentioning the engine size is crucial). Someone may have posted a picture or description of the location.

4. Visual inspection (with caution): Bank 1 refers to the side of the engine where cylinder #1 is located. Sensor 2 is downstream (after) the catalytic converter. With the engine cool, carefully examine the exhaust system on the appropriate side of the engine, looking for a sensor wired into the exhaust pipe after the catalytic converter. Be cautious of hot exhaust components.

Without knowing the specific engine in your 2005 Chevrolet truck, it's impossible to give a precise location. Using the resources mentioned above will help you find the correct location safely.
