Universal MIL Light Eliminator O2 sensor extension elbow
Universal O2 Sensor Extension.
This device will help to stop the MIL light illuminating on off-road vehicles that no longer use a catalyst in the exhaust and are subsequently flagging up a P0420 catalyst efficiency code.
This code is set when the O2 sensor (The sensor AFTER the catalyst) reports to the ECU that your catalyst is inefficient.
This device will fit to vehicles with an M18x1.5 oxygen sensor after the catalyst and is designed to assist in the smoothing out of the O2 sensor signal to the ECU.
The unit also features a copper sealing ring and locking nut which allows you to orientate the sensor exactly where you need it to be.
For off road use only.
Note:
NEVER fit this to the primary Lambda sensor before the catalyst, doing so can cause engine damage.
It must ONLY be fitted to the O2 sensor, which is the sensor found AFTER the catalyst.
