Bosch Camshaft Position Sensors determine engine position based on the location of the camshaft: engine position is used for determining injection and ignition sequence.

Bosch Knock Sensors are highly accurate and sensitive to detect engine knock, ensuring efficient performance and long life of your vehicle.

Bosch Throttle Position Sensors, using OE or better technology, are designed to record vast measurement data with incredible accuracy.

Air Temperature Sensors measure the temperature of the incoming air to the engine. This information is provided to the Engine Control Module (ECU) to determine the correct amount of fuel needed for optimum performance and economy.

Bosch Liquid Temperature Sensors accurately monitor the vital fluids in your vehicle ensuring long and healthy life. The sensor provides information to the Engine Control Unit to keep your engine running strong, safe, and efficient.

Bosch Low Pressure Sensors are compact, durable, and vibration-resistant with outstanding measuring accuracy to ensure your vehicles fluids are at their optimal pressures.

All Bosch High Pressure Sensors provide very reliable and accurate measurements and have extremely fast response times to ensure your vehicle runs as intended.

Bosch Throttle Bodies are manufactured on original equipment (OE) production lines with best-in-class quality.

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.

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.

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.
