10PCS O2 Oxygen R Spacer Adapter Test Extension Extender Adapter CEL M18X1.5 HHO 45mm Bung

Product Description

Lenght is 45mm long

On ODB-II vehicles (96+), the ECU has two O2 rs for diagnostic purposes. The first O2 r is located before the Catalytic Converter. This O2 r is responsible for all the Air/Fuel tuning and is imperative to the operation of the vehicle.

The second O2 r is located after the Catalytic Converter. The whole purpose of this O2 r is to ensure that there is a functioning catalytic converter in the system. The way it can detect this is to make sure that there is a difference in exhaust gaes between the first O2 r and the second. If the same exhaust reading is detected, then the ECU knows that there is either a damaged Catalytic Converter or no Catalytic Converter at all.

The ECU will then trigger a Check-Engine Light. On some instances, the vehicle will be thrown into a "Null" mode where the vehicle will not go over a certain speed and will be basically rendered usele.

This mechanical O2 fix is basically a way to space out the O2 r so that it still reads SOME exhaust gaes but it removes the O2 r from the direct flow of the gaes as to make the ECU believe there is a restriction in the exhaust gaes such as by a Catalyst.

There is NO GUARANTEE that this product will work on your specific application. There are always mixed results depending upon the layout of the exhaust system and the tuning of the ECU, however, this mechanical O2 fix is well known for eliminating most CEL s caused by an O2 r.

NOTE: There is no guarantee that this will eliminate your O2 r CEL. Some vehicles will need their ECU reset if the CEL is triggered before hand.

- O2 r Thread Pitch: M18x1.50
