1. P0133 represents front oxygen sensor readings that are too static.
Check your exhaust for leaks. Fix them first. If you have none, I'd
recommend replacing the oxygen sensor.
2. P0717 is a transmission fault for the input speed sensor. It comes
together with the output speed sensor in one piece called "pulse
generators." I'd be secure with replacing them to address the error
Start with the above. It's possible the cause of the P0133 is also the
cause of the pinging.
You'll need to have the dealer do diagnosis to verify what the problem is
in order to determine whether the repairs are covered. Based on what
you've posted, I'd say it's very unlikely to be a covered powertrain
