I received my new code reader today, I plugged it in and it was giving me the fault code PO638 - Throttle actuator control range/performance bank 1
I realise theres already a thread on this exact fault code but it doesn't really give much information that I can understand as I'm an electrician not a mechanic.
Could someone give me some tips of where I can start to track down the problem please? I was thinking clean the throttle body with carb cleaner and check the connections aren't corroded but after that I'm out of ideas. It seems to have an electronic fault of some sort as well (the electronic fault light sometimes lights up) don't know if this is related but it could be?
Also, how do I know if I've solved it? will the engine management light just disappear?
