Lambda calculus. Lambda calculus (also written as Î»-calculus) is a formal system in mathematical logic for expressing computation based on function abstraction and application using variable binding and substitution.
The lambda sensor measures the amount of unburned oxygen in the engine exhaust. It then sends a signal to the ECU, which adjusts the fuel & air mixture for optimum engine performance.The lambda sensor is important in controlling exhaust emissions.ommon symptoms of lambda sensor failure include excessive fuel consumption, engine surges or stuttering, and the engine management light illuminating. Failure will also result in high hydrocarbon emissions, causing failure at an emissions check (part of the MOT process).
