Does air filter affect O2 sensor?
Registered. If your air filter was dirty enough to set off your O2 sensors then a new air filter should give you a noticeable improvement in power and gas mileage.
How to check and replace an oxygen sensor ( air )?
A P1155 or P1135 code indicates you have a bad sensor. This is common in Toyota and Lexus cars and trucks. Learn how to test the air fuel ratio sensor to see if it is bad, and then learn how to replace the bad sensor. Nice O2 Sensor Socket Kit: http://www.amazon.com/gp/product/B005…
Where is the O2 sensor in a car?
The o2 sensor (oxygen sensor) is located within the exhaust system, upstream of the catalytic converter. Its role is to inform the ECU of the oxygen content of the burned gases that result from combustion. The o2 sensor helps to ensure that the amount of fuel injected into the cylinders for the air-fuel ratio is at an ideal level.
What’s the difference between AFR and O2 sensors?
What distinguishes Air Fuel Ratio Sensors from regular O2 sensors is that the AFR Sensor is what is known as a wide range O2 sensor whereas the basic O2 sensor is a narrow range sensor. It can detect a wider range of air/fuel ratios than the basic O2 sensor.
Can a unburned oil damage the oxygen sensor?
Unburned oil due to engine misfire may contaminate the probe irreversibly. Exhaust leaks also damage the Oxygen Sensor, leading to an intake of air which can cause a dangerous increase in temperature. To ensure the maximum lifespan of the Oxygen Sensor, it is necessary to perform strict engine maintenance (spark plugs, air filter, et al.).
What happens when you change the O2 sensor?
The O2 sensor then sends information to the electronic control unit, or ECU, the vehicle’s computer. The ECU then adjusts the air-to-fuel ratio to optimize the fuel combustion. Sometimes an O2 sensor fails, and you need to replace it.

Why is the O2 sensor in the catalytic converter?
The o2 sensor ensures low fuel consumption as well as reduced pollutants emitted from the engine. It is therefore an important component to help pass vehicle inspection. The latest standards of emissions require the presence of a second lambda probe, located after the catalytic converter in order to determine its effectiveness.
How does intake air filter affect MAF sensor?
Modern intake air systems such as this remove turbulence from air flowing into the MAF sensor. The difference in cross-sectional area decreases the velocity of intake air as it enters the air filter housing causing airborne debris to fall to the bottom of the housing.
