Bosch 13441 oxygen sensor for the 2010 Toyota 4Runner 4-cylinder 2.7L, the 2010-2019 4Runner V6 4.0L and other vehicles measures the air-fuel ratio in the exhaust and sends it to the ECU. The ECU uses that reading to help keep combustion stable and emissions low.
- Heated, narrow-band switching-type design for air-fuel-ratio feedback
- Reaches operating temperature in under 10 seconds for quick closed-loop control and cold-start response
- Integrated heater element and advanced ceramic element
- Built to withstand exhaust streams up to 1,880°F, with a TSP coating that resists vibration, corrosion and contamination
Quick facts
- Part: Bosch 13441 oxygen sensor
- Fits: the 2010 Toyota 4Runner 4-cylinder 2.7L, the 2010-2019 4Runner V6 4.0L and other vehicles
- Position: upstream, downstream, upstream left, upstream right, downstream left, downstream right

A failing oxygen sensor can show up as a check engine light, rough running or poorer fuel economy, though other faults cause those signs too. Before replacing it, look over the wiring and connector for damage and the area around the sensor for exhaust leaks, with the engine off and cool. This listing is one sensor, and the number needed varies by vehicle and engine.
Fits
The vehicles it fits include the 2000-2004 Toyota Tundra V8 4.7L and the 2001-2004 Toyota Sequoia V8 4.7L, among many other Toyota and Lexus models. It is also an O2 sensor for the 2003-2004 Toyota 4Runner V8 4.7L, which takes two. If your car is not named here, open the "Vehicles it fits" section and look up your exact model and engine.
