Lambda /O2 Sensor Removal
When removing the catalytic converter from a petrol vehicle it is likely an engine management light will be illuminated and a fault code for cat efficiency will be stored inside the ECU memory usually P0420. This code can also be raised when fitting a high flow sports catalyst or if a vehicles O2 sensors are failing. By carefully recalibrating the engine ECU data we can disable the function of the second lambda sensor.
The second lambda sensor is used for monitoring the efficiency of the catalytic converter. Disabling the second lambda sensor will allow a decat pipe or high flow cat to be used on a vehicle without triggering an engine management light or associated fault codes.
Decatting a vehicle normally triggers a P0420 fault code (Catalyst System Efficiency Below Threshold (Bank 1)). Our lambda delete service will remove this fault permanently.
Decat services / Lambda Deletes are intended for off-road use vehicles only. Removing a catalytic converter will make your vehicle illegal for use on a public road in the UK.
