Lambda Sensor

[Ric 2001]

Hi Will,
I'm currentlu getting this fault code: Fault code: 16804 - Catalyst System: Bank 1: Efficiency Below Threshold, Can you either map out or disable the 2nd/rear Lambda sensor to stop this?

Hi Ric

Have you upgraded/changed anything?

Nope still got the Milltek Down pipe and sports cat which.. is what I think is causing this to through up the DTC.....

Quote from another thread..... "That code on the 1.8t usually comes up when they run a high flow cat(s), it's why stage 2 code usually disables the 2nd sensor"

Hi Ric

Another re-map can be done if you wish us to disable this for you
