Where is the oxygen sensor on Chevy pickup?

The location of the oxygen sensor (O2 sensor) on a Chevy pickup truck varies greatly depending on the year, engine size, and model of the truck. There's usually more than one.

To find it, you'll need to:

1. Consult your owner's manual: This is the best place to start. The manual will have diagrams showing the location of all sensors.

2. Use a repair manual specific to your year and model: A Haynes or Chilton manual (or similar) will provide detailed diagrams and instructions.

3. Use an online parts diagram: Many auto parts websites (like AutoZone, Advance Auto Parts, Napa Auto Parts) allow you to select your vehicle's year, make, model, and engine, and then view a diagram showing the location of parts, including oxygen sensors.

Generally, O2 sensors are located in the exhaust system: They're often found upstream (before) and downstream (after) the catalytic converter. They're usually threaded into the exhaust manifold or pipe. They're typically wired to the engine control module (ECM).

Without knowing the specifics of your Chevy pickup (year, model, engine), it's impossible to give a precise location. Providing this information will allow for a much more accurate answer.
