Walker Products Oxygen Sensor P/N:250-241273
Walker Products 250-24169 oxygen sensor for the 2010 Toyota 4Runner 4-cylinder 2.7L, the 2010-2020 4Runner V6 4.0L and other vehicles measures the oxygen in the exhaust gas to show how efficiently the engine burns fuel. It is made for a specific application and fitment position, and it gives the ECU the diagnostic feedback that application needs.
A failing sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a malfunction indicator light. None of these signs alone proves the sensor is at fault, since an exhaust or vacuum leak can run the engine poorly too. Inspect the sensor, wiring harness and connector for physical damage as well.
It is a direct-fit oxygen sensor for the 2001-2004 Toyota Sequoia V8 4.7L, the 2000-2004 Toyota Tundra V8 4.7L and the 2003 Toyota 4Runner V8 4.7L. This listing is one sensor, and the fitment calls for one per application. If your car is not named here, check its year, model and engine on the Buyer's Guide tab.

Build and materials
Is Walker Products 250-24169 an oxygen sensor for the 2000-2004 Toyota Tundra V8 4.7L?
Yes. Walker Products 250-24169 is listed for the 2000-2004 Toyota Tundra V8 4.7L, with a quantity of one per application.
Is this an O2 sensor for a 2004 Toyota 4Runner V8 4.7L?
Yes. The 2003-2004 Toyota 4Runner V8 4.7L is in the fitment for this sensor, with a quantity of one.
Is the Walker Products 250-24169 a narrow-band or wideband sensor?
Walker Products 250-24169 is a narrow-band sensor with 4 wires. It determines the oxygen content of the exhaust gas to monitor the air-fuel ratio.
What does the platinum layer on this oxygen sensor do?
The electrodes are made of a gas-permeable platinum layer. A coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases.
Is this oxygen sensor upstream or downstream?
The catalog lists the position as downstream, upstream left, upstream right, downstream left and downstream right. This listing is one sensor.
