Code p0134 is bad oxygen sensor bank #1 code p0170 is bad oxygen sensor not heating up.

Thank you Bender. I did look up the code but I feel like it is too much of a coincidence for it to occur after taking it in and I do not want to bring it back to the same mechanic. Are there any test I can DIY to determine if the sensor is bad?
