Jan 6, 2023 · 02 sensors measure the amount of oxygen in the exhaust and report the level to your vehicle’s computer. There are O2 sensors before and after the catalytic converter. The upstream O2 sensor controls how much fuel is added to the air/fuel mixture. The downstream O2 sensor makes sure the catalytic converter is working.

Oxygen sensor. An oxygen sensor (or lambda sensor, where lambda refers to air–fuel equivalence ratio, usually denoted by λ) or probe or sond, is an electronic device that measures the proportion of oxygen (O 2) in the gas or liquid being analyzed. It was developed by Robert Bosch GmbH during the late 1960s under the supervision of Günter ...
An oxygen sensor is an electronic device that measures the proportion of oxygen in the exhaust gasses exiting an engine. Located in the exhaust system, it provides real-time data to the vehicle’s Engine Control Unit (ECU), which uses this information to adjust the air-fuel mixture for optimal combustion. The primary goal is to maintain this ...
Nov 11, 2024 · Published: Nov 11, 2024. An oxygen sensor (O2) is a vital part of the fuel and emission-control system. It measures the difference in oxygen in the air on the outside of and inside the exhaust. It reports its finding to the ECU to calculate the exact amount of fuel the injector should pulse into the cylinder to create combustion.

The sensor is part of the emissions control system and feeds data to the engine management computer. The goal of the sensor is to help the engine run as efficiently as possible and also to produce as few emissions as possible. A gasoline engine burns gasoline in the presence of oxygen (see How Car Engines Work for complete details).

Mar 21, 2021 · The oxygen sensor must heat up to approximately 600°F before it can accurately measure oxygen in the exhaust. Carmakers add a heater to the oxygen sensor to help it heat up faster. Once the engine coolant temperature reaches a set temp and the oxygen sensor heater heats up the oxygen sensor, the computer starts calculating air/fuel based on the oxygen sensor feedback.
