Hi everyone 

Been getting the SVS service message coming up with P0030-00 HO2S heater control circuit sensor 1

I’ve just replaced the lambda sensor for an identical part, cleaned the egr, throttle body and map sensor yet the fault won’t go away. 

Any ideas of what this could be? Don’t really want to go to a garage and get raped of it could be this it could be that. 

Many thanks.
