I have been randomly popping code P013029 I believe it was for Bank 1 Sensor 1. Is that the one closest to the cab or the muffler? 
Thanks

On the prior models, cylinder #1 or Bank #1 is the one closest to the muffler or rear of the machine. Also the wire leading to the O2 sensor on the newer ones is known to break at the sensor or the connector has problems like coming apart or corroding. There's a post here with pics somewhere.
