I have a 2010 Murano that occasionally hesitates from a stop for a second or two after pressing the accelerator pedal. The engine does not rev, it acts like I haven't depressed the gas pedal at all. It has not displayed a check engine light at all and my OBD II scanner doesn't show any error codes. I have replaced the TB and cleaned the MAF sensor with no change. I took it to my local mechanic and he found two transmission codes P1701 and P0615 and suggested taking it to Nissan or a Transmission shop. Does this seem to be a major CVT issue even though the engine doesn't rev at all? Any help would be greatly appreciated. Thank you

Both codes seem to relate to a power issue with your TCM/PCM. Fix that first.

Just wondering if you ever got this resolved? My 2012 is doing the same thing.

Thank you for providing good information in your post. Appreciate your taking the time to present what you posted. Lets start with that two different scan tools were used and one did not show any DTC's while the other scan tool showed DTC's.

So, do you want to trust the DTC's? Me, I wouldn't and here is why. That P0615, that will cause a dash warning light to come on the dash and you already said, there is no dash warning light. Therefore, the scan tool the other person used cannot be trusted.

Now, the fault. Lets stick with the components that are involved with your pressing the accelerator pedal. There is the accelerator pedal and the throttle. At ignition on, view the live data, TPS 1, TPS 2, APP 1, APP 2.

Actually, reading that PID data, you need to buy the book. "A guide to vehicle diagnostics" written by Cascanet and Schnell. I think the throttle and accelerator is covered toward the end of the book, under "Correlation". I would have to write too much here, the book is less than $10 and will give you exactly what you need. Plus you will learn a lot of other things as well.
