Hey everyone I keep getting the P0420 code after fitting a sports car and i dont want to remap my ECU Who has this on their car and does it work?
You need an oxygen sensor simulator. Easy to install and works great. Just google it and the company will come up. They make a MINI specific model.
Way Motor Works sells them.. You might want to send him a message... It's not an uncommon fault code due to the reduced cel count in the sport cat... Since Akrapovic sells this piece in addition to their down pipe.... The assumption is it works to trick the ecu.... The other direction is to go with the O2 simulator... it's a simple spacer that moves the O2 sensor a little farther out of the exhaust stream.... Here...O2 Simulator, mini catalytic Converter cel fix Sorry, I have no experience with either of these items...
Yup i installed a sports cat - 200 cell one on my 2011 JCW Well i tried an o2 spacer and it didnt work - Still the EML light The shipping for that other space is $80 then $30 and no returns if it doesnt work At least if the delete R doesnt work i can get my monies back Thanks metal man i will drop Way motors a message
I have the delete r and the Akrapovic DP. I still get the light with the P0420 code ever few hundred miles but it clears it self, then comes back a few hundred miles later.
The O2 sensor simulator is a small circuit board that you wire in instead of the rear sensor. It sends a signal to the ECU that it accepts and you get no check engine lights. I ran one on my last car with an empty cat on my header and never had a code.
