what is an oxygen sensor on a 2008 hyundai elantra
The HYUNDAI Elantra oxygen sensor supplies real time information about the engine's exhaust gas oxygen content to the powertrain control module. This information is used primarily to help calculate fuel delivery to the engine, which changes continuously while it is running.he oxygen sensor is sometimes referred to as a Lambda sensor on some European cars. Changes in the amount of exhaust gas oxygen result in a voltage change that is monitored by the vehicle's powertrain control module.
