The issue I am having is a few days ago, the car went into limp home mode. So I had the gentleman I bought it from take a look at it(since he knows a lot about Volvo and i don't) and the code he got on it was for the TPS. Took the car into a shop to have them diagnose the issue and they let me know that the ETM needs to be replaced and the estimated cost for that is $900...
Now what I want to know is if I buy a rebuilt ETM from eBay for about $100, can I just replace it that way or do I need to have a professional sync it with the ECM...? Please answer in the most simplest way possible so I can understand completely.. Im not a mechanic lol.. Thank you!
