Oxygen Sensor Canceling Spacers
Our Oxygen Sensor Canceling Spacers is used to cancel p0420 codes for people running high flow cats or test pipes. These spacers trick the rear o2 sensor into thinking the engine and catalytic converter is operating properly. This eliminates the P0420, p0421, p0422 & p0423 DTC fault codes after the codes are cleared. This Oxygen Sensor Canceling Spacers will not repair codes associated with the o2 sensor and it’s eternal heating element or functionality. you have to have a good o2 sensor in order for this to work properly. See DTC codes above.
These spacers will fit most European o2 sensors. Please check your application before ordering.
Oxygen Sensor Info:
In vehicles with EURO 3 and higher vehicle emissions standards the second lambda oxygen sensor emulator is located after the catalytic converter. It plays a diagnostics role. If it detects any irregularities on the basis of the data from the engine control unit it displays an error on the dashboard and the engine can switch into emergency mode (depending on the make of car). It is often manifested by big power drop. These problems arise in the event of removal of the catalyst, its low efficiency, or its replacement with jet pump. In such situations, it becomes necessary to mount THE SECOND LAMBDA OXYGEN SENSOR EXTENDER.
The catalyst can effectively reduce the power output of 2 to 3%, and the maximum power speed of up to 5%. Its removal and the use of emulator is the easiest way to low-cost raise of power; Furthermore our Oxygen Sensor Canceling Spacers may help in case of problems with the LPG installation. As a result, the detection of very rich mixture will display the CHECK ENGINE on the dashboard.
Polished front surfaces enabling perfect tightening.
Washer in the set, ability to adjust the angle of screwing in the extender.
Threads are made with dedicated tool, perfect accuracy and repeatability.
Exhaust gas inlet hole 2 mm; In extreme situations narrowing of the inlet hole prevents motor failure (driving at high speed).
Perfect for tight awkward spaces, where there is no room for the straight extenders
