Engine Management
Bosch Switching-Type Oxygen (O2) sensors provide precise air-fuel-ratio measurements to the ECU, ensuring stable combustion control and helping reduce emissions across a wide range of operating conditions. Evolving from the original thimble sensor Bosch pioneered in 1976, Bosch later developed planar narrowband designs that offer faster light-off, improved lambda accuracy, and quicker closed-loop operation. Using advanced ceramic elements, optimized heater control, and high-temperature-resistant materials, Bosch Oxygen (O2) sensors deliver consistent performance even under harsh thermal and vibration loads. Backed by more than five decades of OE development, Bosch supplies a full line of durable, accurate Oxygen (O2) sensors to the aftermarket with the same OE-proven quality trusted by vehicle manufacturers.
Bosch Wideband A/F Oxygen (O2) sensors provide continuous, high-precision measurements of the air-fuel ratio across the full lambda range, giving the ECU far more detailed information than traditional switching sensors. This enables exceptionally accurate air-fuel mixture control — supporting improved fuel efficiency, engine performance, and reduced emissions under all operating conditions. Bosch pioneered the first Wideband A/F Oxygen (O2) sensor, introducing the planar pump-cell design that has become the global standard for modern engine management and low-emission technologies. With fast light-off, optimized heater control, and robust ceramic construction, Bosch Wideband A/F Oxygen (O2) sensors deliver reliable performance even during rapid load changes and harsh thermal cycles. Backed by more than five decades of OE development, Bosch supplies a full line of durable, accurate Oxygen (O2) sensors to the aftermarket with the same OE-proven quality trusted by vehicle manufacturers.
Bosch SmartLink™ Universal Oxygen (O2) sensors combine OE-specification base sensors with a flexible, patented Posi-Lock® connector system designed for fast, reliable installation across a wide range of vehicles. Each sensor uses the same high-quality zirconia ceramic element and heater design found in Bosch OE applications, ensuring accurate air-fuel-ratio feedback and dependable performance. The SmartLink™ system features Posi-Lock® connectors that create secure, high-temperature & weather resistant electrical connections without the need for soldering, crimping, or specialty tools — allowing technicians to adapt the sensor to existing harnesses quickly and confidently. The extended lead length provides added flexibility for vehicles with damaged or shortened wiring, and the connector system can be reopened and reused if adjustments are needed. Engineered to provide an easy, universal installation experience, Bosch SmartLink™ Universal Oxygen (O2) sensors deliver professional-grade fit and function with the same OE-proven quality and dependability trusted by vehicle manufacturers.

Standard narrow band type Oxygen Sensors operate between 0 and 1 volts, and are only capable of accurately measuring a stoichiometric air/fuel ratio (e.g. 14.7:1). A richer or leaner condition results in an abrupt voltage change and is only useful for qualitative determination.
The Lambda sensor consists of two cells. It is made up of a Nernst type potentiometric oxygen concentration cell and an amperometric oxygen pump cell.
Tire and Chassis
Not only did Bosch invent the Electronic Stabilization Program (ESP) – the technology that improves a vehicle’s stability by detecting / reducing loss of traction – but it also was the first company to fit Anti-locking Braking Systems (ABS) into mass production. The ABS applies brake fluid that engages the brake calipers and pads, which slows a car without locking up the tires. The wheel speed sensor transmits the wheel speed to the ECU, which determines how much pressure the ABS can safely apply. Bosch is an original equipment global leader in wheel speed sensor technology. Bosch Wheel Speed Sensors (WSS) sensors ensure they deliver information on the wheels' rotation characteristics to the ABS/ESP control unit.
The new Bosch Universal Sensors for Tire Pressure Monitoring Systems (TPMS) measure the air pressure of the vehicle's tires in real time and transmit it directly to the control unit by radio. Universal, compact and easily programmable, Bosch QUICK FIT sensors offer a vehicle coverage of over 90% with just two part numbers.
Diesel Parts
Ensures proper fluid temperature and thaws DEF when below 12°F
Bosch Particulate Matter (PM) sensors continuously monitor the function of the Diesel Particulate Filter (DPF) via direct measurement of soot concentration to help reduce particulate emissions by up to 99%. An evolution from older ΔP sensor’s indirect estimate of soot, Bosch pioneered resistive-measurement Particulate Matter sensors in order to provide precise real-time data to the ECU. With accurate soot data, the ECU can avoid unnecessary DPF regenerations – increasing fuel efficiency, reducing ash buildup, and extending the lifespan of aftertreatment components such as the Diesel Particulate Filter. Bosch offers a full line of robust, durable, and accurate Particulate Matter sensors to the aftermarket with the same sensors currently trusted by OE manufacturers.
Bosch Exhaust Gas Temperature (EGT) sensors provide accurate, real-time monitoring of exhaust temperatures to protect key engine and aftertreatment components. By ensuring the optimal temperature range, they help prevent damage to turbos, catalytic converters, DPF's, and SCR systems while enabling efficient regeneration and reduced emissions. EGT sensors also supply the ECU with critical data to help optimize dosing and initiate regeneration events at the right time. Built with robust, heat-resistant materials and validated to OE standards, Bosch EGT sensors deliver long service life and reliable performance even under extreme thermal loads.
Bosch Nitrogen Oxide (NOx) sensors precisely measure the concentration of nitrogen oxides in the exhaust stream to ensure efficient SCR catalyst performance. By delivering real-time data to the ECU, NOx sensors enable accurate dosing of DEF, improved fuel efficiency, and compliance with strict emission standards. Built with advanced electrochemical sensing elements and robust housings to withstand extreme exhaust conditions, Bosch NOx sensors provide long service life and consistent accuracy. Bosch offers a full line of robust, durable, and accurate NOx sensors to the aftermarket with the same sensors currently trusted by OE manufacturers.
