Research on Oxygen Sensor for Lexus IS300

An oxygen sensor measures the unburned oxygen in the exhaust as it exits the engine. A Lexus IS300 o2 sensor diagram will show the location of the sensor in the exhaust manifold. The reason for the measure is to gauge the fuel mixture and see if it is burning rich or lean. This information is sent to your vehicles computer and is used to help your car run efficiently and to reduce emissions. If you see your check engine light come on have your Lexus scanned and see if you get the code that will point to the Lexus IS300 o2 sensor bank 1 sensor 1 as the problem. If you have an oxygen sensor problem, then your car may have a poor idle, a problem starting, and high fuel consumption. These are all IS300 o2 sensor B1S1 possible symptoms.

Abnormal Behavior

Whenever my car is idling and I hit the gas it bogs down like it's going to stall but then revs up. Does anyone know what this could be? Always the first step in this situation is to have your car scanned and determine what the code means. Sometimes it is the oxygen sensor and you can find the IS300 o2 sensor wiring diagram, find its exact location, and change it. If it is not the O2 sensor, there is another option that you can check. Sometimes you may have a dirty MAF or Mass Air Flow sensor. Take this off and see the results first. Just to make things easier, the best tool to remove and do a sensor replacement is called an oxygen sensor socket. Simply using this tool and changing your oxygen sensor can help you pass your emissions test.

Gasoline and Oxygen

The problem with a bad oxygen sensor is that you get the wrong mix of gasoline and oxygen which can increase the pollutants flowing through your exhaust. If you have Lexus IS300 o2 sensor bank 1 sensor 2 problems and this happens the mixture can prematurely cause your catalytic converter to fail or even worse, damage your engine. A failed catalytic converter can be an expensive repair. It is important to get this addressed as soon as possible. An important point is that intake and exhaust leaks can trigger problems in your oxygen sensors. If this is the case a problem code may show but there may be nothing wrong with the oxygen sensor. Simply fixing any leaks around the IS300 o2 sensor B2 S1 may resolve the situation. Often the repair can be very simple.

Proper Mixture Cost

Having a local repair shop change your oxygen sensors will cost a lot for both in the rear. With the proper sensor socket, you can do the job yourself quickly. A faulty oxygen sensor is a primary reason that vehicles fail the emissions test at inspection stations. It is important to fix. All you need is a little time. You can save money on any O2 sensor including the one for your Lexus IS300 at PartsGeek.com. Having the IS300 o2 sensor part number will help. We sell parts and accessories exclusively online. We don't have a big building and a big overhead. This translates into better prices for you.

Very happy customer, parts shipped as scheduled, parts were new in boxes and very happy once more

2003 Lexus IS300 Oxygen Sensor

Very Satisfied
Reviewer: Never too loud

Sensor fit perfectly no modification needed just remove original and instal new one, I have tried to use other brands on Lexus but there's always something that goes wrong either the part is a generic design and a few mods have to be done or the part is just "cheap" and last a couple of weeks, if you want your Lexus to perform the way it was meant to use Denso brand parts.
