Walker Products 250-24623 oxygen sensor for the 2014-2015 Lexus IS250 V6 2.5L and other vehicles measures the oxygen in the exhaust gas to monitor combustion efficiency. Every part number is made for its specific application and fitment position, and it gives the ECU the diagnostic feedback it expects.
- Measures the oxygen content of the exhaust gas to monitor the air-fuel ratio
- Oxygen readings let the air-fuel mixture be fine-tuned, which supports fuel economy
- Monitors exhaust gases to help reduce pollutants
- Electrodes with a gas-permeable platinum layer
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Narrow-band sensor with 4 wires
Quick facts
- Part: Walker Products 250-24623 oxygen sensor
- Fits: 2014-2015 Lexus IS250 V6 2.5L and other vehicles
- Position: Downstream, downstream left, downstream right, downstream front
- Condition: New
Rough running, higher fuel consumption or a lit malfunction indicator light can mean the sensor is worn, though a damaged wiring harness or connector can be behind them as well, so look both over for physical damage before replacing the sensor.
Fits
It is a direct-fit oxygen sensor replacement for the 2014-2015 Lexus IS250 V6 2.5L, an oxygen sensor for the 2004-2009 Toyota Prius 4-cylinder 1.5L, and it also fits the 1998-2000 Toyota Sienna V6 3.0L along with many other vehicles. If your car is not one of these, open the "Vehicles it fits" section and check your exact model and engine there. This listing is one sensor, and the 2014-2015 Lexus IS250 V6 2.5L takes one.

Frequently Asked Questions
Is this oxygen sensor right for the 1998-2000 Toyota Sienna V6 3.0L?
Yes. The Walker Products 250-24623 is listed for the 1998-2000 Toyota Sienna V6 3.0L, and the quantity per vehicle is one.
Is the Walker Products 250-24623 an upstream or downstream sensor?
It is a downstream sensor. The Walker Products 250-24623 is listed with downstream, downstream left, downstream right and downstream front positions.
Is the Walker Products 250-24623 a narrow-band or wideband sensor?
This oxygen sensor is a narrow-band type with 4 wires and an M18 - 1.5 thread.
What does the coating on this oxygen sensor protect?
The electrodes have a gas-permeable platinum layer. The coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases.
Can a failing oxygen sensor store a fault code in the ECU?
Newer vehicles store fault codes in the ECU, and some relate to the affected sensor and its associated systems. A shop can read those codes.
