Walker Products 250-24837 rear oxygen sensor for the 2006-2010 Toyota Highlander V6 3.3L, the 2009-2014 Highlander 4-cylinder 2.7L, the 2011-2016 Highlander V6 3.5L and other vehicles measures the oxygen in the exhaust gas to show combustion efficiency. Every part number is made for one application and fitment position and returns the diagnostic feedback the ECU needs.
- Narrow-band sensor, 4-W
- Oxygen readings let the air-fuel mixture be fine-tuned, which supports fuel economy
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust
- Electrodes with a gas-permeable platinum layer
- Monitors exhaust gases to help reduce pollutants
Quick facts

A failing oxygen sensor can show up as rough running, higher fuel consumption or a lit malfunction indicator light. Before you replace the sensor, look the wiring harness and connector over for physical damage, with the engine off and cool, so you know the sensor itself is the cause.
Fits
This direct-fit narrow-band sensor is an oxygen sensor for the 2010-2015 Lexus RX350 V6 3.5L and the 2010-2015 Lexus RX450h V6 3.5L, along with the Highlander runs named above. Open the "Vehicles it fits" section to check your exact model and engine. This listing is one sensor, and the 2006-2010 Toyota Highlander V6 3.3L takes one.

Frequently Asked Questions
Is this the right Toyota Highlander oxygen sensor for the 2011-2016 Highlander V6 3.5L?
Yes. Walker Products 250-24837 is a downstream rear sensor that fits the 2011-2016 Toyota Highlander V6 3.5L, and that engine takes one.
Does the electrode on this narrow-band oxygen sensor have a coating?
Yes. A coating shields the electrode surfaces from contamination and erosion by combustion residue, and the electrodes use a gas-permeable platinum layer.
Is this Walker Products oxygen sensor an upstream or downstream sensor?
Walker Products 250-24837 is a downstream rear sensor. It is a narrow-band, direct-fit type listed as 4-W.
Will a bad oxygen sensor set a fault code in the ECU?
It can. Newer vehicles store fault codes in the ECU, and some of them relate to the affected sensor and its associated systems.
What thread size does this narrow-band oxygen sensor have?
This rear oxygen sensor has an M18 - 1.5 thread. The listing is one sensor.
