Catalyst emulator and catalyst - off DTC P0420 error.
Emulator (electronic simulator), usually
is to be installed after catalyst removal or in case of failure of the rear lambda probe (sensor)
B * S2. The emulator processes the signal that comes from the lambda sensor. This
microprocessor device generates signals for the correct operation of
the engine control system in conditions when the catalyst is removed or defective. A converted signal from the emulator
in such a form as from a serviceable catalyst converter
is sent to the electronic control unit (ECU) input. Thus, the ECU considers that the automotive catalyst
works properly and its replacement is no longer required, it is replaced by a casing catalyst
or a flame arrester (Stronger).
The emulators offered by us are a fully operational device and have a waterproof casing filled with compound. Emulators are supplied configured by default.
This lambda sensor emulator is suitable for all types of cars. When buying it, a guarantee for the re-sult of 2 years is provided. It is possible to adjust the parameters without a computer - with a magnet.
In order to ensure compatibility with all the petrol cars, we produce 4 types of emulators: SK-02, SK-06, SK-07, SK-08. You can choose the emulator by the brand of the car at the top of the page. Almost all emulators have the ability to adjust (if necessary) to achieve the best result, for example, to save fuel or on “complex” cars.
