I just finished putting on a new timing belt. As soon as I started the car I got a check engine, cruise light blinking and a traction light. The car runs beautifully. I took it to a local garage for a scan and it's showing O2 sensor issue. Doesn't it seem odd this would show up immediately after a timing belt job. Never had any lights on before.:|

I took it to Advance Auto and got a P0031 and P0037 code, both O2 sensor heater codes. I checked the heater circuits at the sensor and both seem good. Can they both be bad at the same time ?
