    Hi again...Just had both coolant and sensor replaced under warranty. Check engine light coming on again!

    Hoping it's just a faulty part but I'm not liking how involved I've become with Toyota Service Dept.

    This is a very reputable dealership. Even customers in waiting room offer up that I'll like quality of service. Each time I've brought car in I've had to bring it back to fix or adjust something. Mostly minor but gee whiz.

    Anyone else have multiple emissions parts fail..one after the other? Bringing it in at noon to see what's up.

    From what I've seen and heard, it's fairly common to return for service after coolant system work. This engine is hard to bleed correctly and even the paid pros get it wrong sometimes. Good luck with it.

    Thanks, Andrew.

    Toyota tech had to call engineer dept. to troubleshoot. A possible blockage in lines. Lines were cleared and reversed to see if that is problem. I'm hoping that's it. Now I have to figure out how to uncover my Pria from the icy snow. Wishing I was back in CA!
