I’m going to go look at a 2011 IS 250 with 157k miles on it for about $8000. The guy told me its running a few codes: p0101, p0158, p0500, and p0607. The one I’m worried about is p0607. Is it likely that the O2 sensor and other sensors are causing the ECM code to appear? He said it drives perfectly fine. What are the chances I can just replace all three sensors and be fine?
