The Lexus IS250 has two oxygen sensors. One is located near the firewall and in front of the catalytic converter, while the other is located behind the converter closer to the rear. These sensors should primarily be the same part, just with different lengths of wiring.

How much does it cost to replace 4 O2 sensors?
Many sensors, nonetheless, cost between $20 and $100. Your mechanic’s labor costs also likely vary based on a few factors, including how difficult it is to access your sensors. Typically, labor costs for a sensor replacement are around $150.
What symptoms does a bad O2 sensor cause?
Signs a Vehicle has a Bad O2 Sensor
- Check Engine Light Comes On.
- Noticeable Loss of Fuel Efficiency.
- Sulfur or ‘Rotten Egg’ smell from Exhaust.
- Black smoke from exhaust.
- Emission levels reach high levels.
- Your engine hesitates, skips, begins bucking or has power surges.
Where IS the O2 sensor on a Lexus IS 250?
The Lexus will have a bank 1 and a bank 2 O2 sensor: one is near the firewall and in front of the catalytic converter; the other is behind the converter closer to the rear. They should primarily be the same part, just different lengths of wiring.
Can I replace 1 O2 sensor?
Manufacturers recommend replacing O2 sensors in pairs (both Upstream or both Downstream). An older, slower sensor can cause an imbalance in the engine management system, leading to poor fuel economy and possible damage to the catalytic converter.
Is it OK to drive with a bad O2 sensor?
Can I Drive My Car With A Bad Oxygen Sensor? We recommend against driving with a bad O2 sensor as the powertrain is not running on the correct fuel mixture. While it may perform fine in the beginning, if your engine is running rich and using too much fuel it might begin to clog the catalytic converter.
How do I know how many O2 sensors I have?
How Many Oxygen Sensors Are There in My Car? Most cars will have several oxygen sensors. There will be one in front of the catalytic converter and one in every exhaust manifold. Modern vehicles usually have at least four oxygen sensors placed at key points in the exhaust system.
How many oxygen sensors does a Lexus IS250 have?
Essentially, on the is250, there are four to be considered. There are 2 Upstream sensors (Bank 1 Sensor 1 and Bank 2 Sensor 1) and 2 Downstream sensors located after the cats (Bank 1 Sensor 2 and Bank 2 Sensor 2).
How much does it cost to replace the oxygen sensor on a Lexus IS250?
The average cost for Lexus IS250 Oxygen Sensor Replacement is $317. Drop it off at our shop and pick it up a few hours later, or save time and have our Delivery mechanics come to you.
How much does it cost to replace a O2 sensor on a Lexus?
The average cost for a Lexus ES350 Oxygen Sensor Replacement is between $382 and $410. Labor costs are estimated between $109 and $137 while parts are typically priced around $273. This range does not include taxes and fees, and does not factor in your unique location. Related repairs may also be needed.
Do I have to replace all 4 O2 sensors?
Do I need to replace all of the sensors at once? It is best to replace O2 sensors in pairs. For example, if you replace the downstream left sensor, you should also replace the downstream right.
