The oxygen sensor DK 27

DK oxygen sensor 27 (lambda probe, 31602-3826020 analogue 27.3855, SIEMENS VDO 5wk 91000-G), OZA334-SZ3, 5WK91000

Four-sensor, with a heater for use in the system of neutralization of exhaust gases of car engines, both as control supporting air-fuel ratio λ = 1, as well as a diagnostic sensor for controlling the composition of the mixture of the catalytic converter in the diagnostic system.

The oxygen sensor is going to a modern high-tech equipment. Through the use of modern materials improved application quality of the working material of zirconia, which provided a more reliable operation of the entire sensor.
