had a remap at the weekend and turned up a faulty uppipe sensor (sorry dont know correct name) so was advised to do the resistor mod, done on monday and got ecu reset, all well until today when light has come on again,

so I've checked the resistor and it looks ok, how can you tell if its faulty? how do I reset? is this a common problem with this mod?

any help greatly recieved!

 

think I may have put a lower value resistor in, should i have fited a 2.2 .5watt one, think mine is a 2k 1/4 watt resistor
