Lambda sensors are subject to extreme conditions. A properly functioning lambda sensor forms the basis for reliable engine operation and thus fuel economy, low pollutant emissions, and good exhaust gas values.
Bosch lambda sensors are available for most vehicles. They are unbeatable thanks to their long service life, excellent operation, and optimum engine compatibility. They make a significant contribution to saving the driver money and protecting the environment.
Bosch invented the lambda sensor and is first choice for lambda sensors around the world. An annual production of around 45 million lambda sensors impressively demonstrates the high production expertise delivered by Bosch. It therefore comes as no surprise that most vehicle manufacturers put their trust in Bosch lambda sensors.
Minimum effort for maximum benefit: The lambda sensor should be checked over each time the workshop performs maintenance – regularly every 30 000 km. In the event of aging the lambda sensor should be replaced.
A hot job for optimum CAT performance: Modern lambda sensors help ensure the catalytic converter can thoroughly clean exhaust gases. Together with the engine control unit, lambda sensors serve to ensure the optimum mixture composition, so the engine keeps running – in a powerful, clean, and efficient manner.
In 1976 the series production of Bosch lambda sensors began. This was triggered by the strict emission regulations in the USA. Together with the 3-way catalytic converter, the lambda sensor made it possible to regulate the air/fuel mixture. Since 1993 the planar sensor has been recognized as the state-of-the-art technology: It is ready for operation in no time and can thus regulate the exhaust gas as early as the cold-start phase.
