P Code / Fault Code / DTC Delete
Permanently removing fault codes from the engine management system is a very useful process when modifying a vehicle. Removing components such as swirl flaps, EGR valves, other modules etc.. for purpose of performance modification or motorsport will often cause a fault code to be stored in the ECU memory along with lights on the dash and limp mode. By recoding the ECU data and permanently removing the specific fault code we can prevent the dash lights from being displayed and prevent the vehicle from entering limp mode.
