With the wideband lambda sensor, the oxygen concentration in the exhaust gas can be determined over a wide range for calculation of the air/fuel ratio in the combustion chamber.

ECM’s Lambda 5220 is a powerful, “next generation” wideband Lambda and O2 analyzer. In addition to providing outstanding measurement range and accuracy, the Lambda 5220 …

This sensor is designed to measure the proportion of oxygen in exhaust gases of automotive engines (gas-oline or Diesel). The wide band lambda sensor LSU 4.9 is a planar ZrO2 dual …

May 24, 2022 · Over time, old sensors degrade, causing incorrect fuel mixtures (too rich or too lean). Replacing them with a high-precision Marsflex sensor restores proper combustion, …

Switches the lambda sensor, displays battery voltage, oxygen percentage, lambda and AFR (air-fuel ratio) for different fuels on the smartphone screen. Is available for the following …

Wideband/Air-Fuel sensors perform the same function as a regular O2 sensor, but they precisely measure the amount oxygen in the exhaust rather than just switching between rich (too much …

Mar 14, 2025 · Wideband lambda sensors represent advanced automotive diagnostic technology that precisely measures air-fuel ratios through sophisticated voltage output mechanisms.

The solution to this is a wideband oxygen sensor, which tells the ECU quite precisely what the air to fuel ratio is based on the amount of oxygen remaining in the exhaust gas.

Our DT3-AF1 A/F sensor/controller systems uses a Bosch 5 wire oxygen sensor to accurately measure A/F ratio, or Lambda, over a wide range of values from approximately .6 to 1.3 Lambda.

NGK Spark Plugs (NTK) has two families of wideband sensors, non-cofired (on left) and co-fired (on right). Both have five wires and they can be identified by appearance.
