Check Engine light came on had it checked and O2 sensor was changed. Light came on two days later the trouble code is 17. Any idea what this is. Car runs great no power loss or increased fuel consumption just the annoying light.

17 is fuel injector.

if no other problem such as shaking of engine, just delete it.

 

My scanner states (P00)17 is Crankshaft Position - Camshaft. Position correlation (Bank 1 Sensor B) but SLEEPWALKER has access to more technical info than I.
If you cancel it and it comes back it indicates a problem.
Need to consider Mileage, Service Intervals.
Since yours is a V6 and it states Bank 2 maybe the sensor for camshaft sensor(s) on Bank 1 is bad. (Crankshaft sensor common) For info Code 16 is the sensor for Bank 1 Sensor A Codes 18 and 19 are the same for Bank 2.
Not sure how camshaft position is sensed independent of crankshaft and why two sensors / bank?
