Karlsruhe, Germany – Exhaust-gas temperature sensors play an important role in modern vehicles, particularly when it comes to meeting emissions limits. Defective or worn sensors should therefore be replaced promptly. With this in mind, exhaust-gas temperature sensors have been part of the Bosch portfolio for the workshop market since 2020. A further 107 part numbers were added to the range at the end of 2023. The complete portfolio now includes around 50 different exhaust-gas temperature sensors for heavy and light trucks and over 230 for passenger cars. Ten percent of the sensors in the portfolio are suitable for hybrid applications in the European market. The more than 250 part numbers in the portfolio cover 45 million vehicles featuring temperature sensors in Europe. The sensors are now available from stock for workshops to order. Together with particulate sensors and nitrogen oxide sensors (NOx), workshops can draw on a comprehensive range of sensors for the precise control of exhaust-gas composition. With its many years of systems expertise in exhaust-gas treatment, Bosch is one of the leading suppliers of exhaust-gas sensors. At Bosch, all sensors are tested to the same high quality standards as original equipment. In 2024, the company is planning to include some 70 further exhaust-gas sensors in its workshop portfolio.

Sensors in the exhaust tract provide precise data for on-board diagnostics

Exhaust-gas temperature sensors, which can be installed at several points in the exhaust tract of diesel, gasoline, and hybrid engines, measure the exhaust-gas temperature and transmit it as a voltage signal to the engine control unit. A diagnostic tester such as the Bosch KTS can be used to check them in the on-board diagnostic system. This allows mechanics to easily identify worn or defective sensors. Since a union nut is all that is needed to install the sensors, defective ones can also be quickly and easily replaced.
