Hi my 2002 2.4 s60 had problem where the codes said throttle body[bosch] stuck open. I pulled the throttle body and cleaned it. My searching said the Bosch tb rarely goes bad but that the wiring harness does often go bad. From looking at the tb and testing it with a ohm meter, I'm pretty sure mine is good. I'm going to put the cleaned tb back on with a new hareness . Is the harness just a replacement harness or is it updated special one made to fix the problem? I bought the wiring plug to the tb side but I've heard that the harness goes bad at the computer, side I think the harness pins lose contact. Is that true? It's time to finally get this fixed anyone got any advice. Thanks
