Walker Products 250-24244 oxygen sensor for the 2014-2015 Lexus IS250 V6 2.5L and other vehicles measures combustion efficiency from the amount of oxygen in the exhaust gas. This direct-fit, narrow-band, 4-wire sensor is built for its specific application and downstream position.
- Measures oxygen levels to fine-tune the air-fuel ratio and improve fuel economy
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Electrodes made of a gas-permeable platinum layer
- Monitors exhaust gases to help reduce pollutants
Quick facts
- Part: Walker Products 250-24244 oxygen sensor
- Fits: 2014-2015 Lexus IS250 V6 2.5L and other vehicles
- Position: Downstream left, downstream right
- Condition: New
A failing sensor can make the engine run poorly, raise fuel consumption and exhaust emissions, or turn on the malfunction indicator light. Before you replace the sensor, look over its wiring harness and connector for physical damage, since a problem there can mimic a bad sensor.
Fits
The 2014-2015 Lexus IS250 V6 2.5L, the 2014-2018 Lexus IS350 V6 3.5L and the 2015-2018 Lexus RC350 V6 3.5L are covered by this oxygen sensor replacement, as are more models.

Frequently Asked Questions
Is this a Lexus IS250 oxygen sensor for the 2014-2015 model with the V6 2.5L?
Yes. Walker Products 250-24244 is listed for the 2014-2015 Lexus IS250 V6 2.5L and also fits other vehicles. Open the "Vehicles it fits" section to check your exact model and engine.
Is this Walker Products oxygen sensor narrow-band?
Yes. Walker Products 250-24244 is a narrow-band, 4-wire sensor with an M18 - 1.5 thread and a direct-fit design.
Is this an upstream or downstream oxygen sensor?
This one is a downstream sensor, listed for the downstream left and downstream right positions.
Will a failing oxygen sensor on a newer car store a fault code?
Yes. Newer vehicles store fault codes in the ECU, and some relate to the affected sensor and its associated systems. Reading the stored codes is a job a shop can do.
What are the electrodes on this oxygen sensor made of?
Walker Products 250-24244 has electrodes made of a gas-permeable platinum layer. A coating keeps combustion residue and particulates in the exhaust from contaminating or eroding the electrode surfaces.
