The Dreaded P0174 Trouble Code
I recently sold my Goldwing Gl1800 as I no longer feel confident on an 800 plus pound bike with the wife and luggage. About 2 weeks ago I replaced it with a 2012 Spyder RT Limited with 3700 original miles. The bike looks and runs like new, however, over the weekend, while on a short ride into the mountains 125 miles N. E. of Phoenix the check engine light came on. The code came up P0174. Upon checking the forum, I learned of many members with this same problem. Many have spent hundreds of dollars and made numerous return trips to dealer service, and still have an ongoing problem. I took mine to a dealer in N.W. Phoenix a couple days ago, and got a call from the service advisor today. He told me the problem was diagnosed as a bad battery and the sensor is throwing the code due to low voltage. Working at a new car dealership I have seen erroneous codes due to low voltage (battery) problems, and I am hoping that is the case here. I approved the installation of a new battery, and will pick the bike up this weekend. Here's hoping this ends the problem.

& more info about P0174 According to Spyder codes app:
system too lean Bank 2
check injector & fuel supply system. Yes a low battery can cause faults but usally its multiple not just one all by itself, so there may be a lingering problem worth keeping an eye out for, running some fuel treatment also wouldn't hurt. Run some ethonal free gas if you can find

hope does come out all fine for you, be glad it was not the HORRIBLE "DESS code"

Had same problem with my (ex) '12. In and out of shop for months until a dealership (who was tired of dealing with me and my problem) began tracing "fuel" system after throttle assembly, plugs, vacuum lines, etc were replaced. Turns out the Pressure Regulator was installed upside down (still can't figure that one out). When that problem was corrected the RT ran great. I put 61k b4 upgrading to current '16.

Our Spyders computers are very sensitive to low voltage / amperage so this may very well be the case here
.You Spyder is now 6 years old, the low mileage has little to do with Battery strength if it is the original batt. It is OLD
. The thing that might be an issue ( @ 6 yrs.) is the Vacuum hoses at the Throttle body ( if they are the original ones )....BRP doesn't use SILICONE versions for them and they probably have
microscopic
cracks which will cause leaks and issues...
. they may look OK, but likely aren't change them out for silicone

I had the same code on out 11 RTS. For a while we would pull over pull the key out do a weather dance and keeping riding. It got to a point where it was happening all the time. It turned out to be the throttle bodies. Luckily it was replaced under warranty. In the older models this was a pretty regular occurrence that I saw posted here. Especially for the 2010-2013 RT's (998)

Seems like the throttle body replacement would be a worst case scenario. What did that cost, or was it warrantied?

Update: I just picked up the Spyder, for the second time on Saturday. The new battery install did not solve the problem. the check engine light returned after about 300 miles. The Dealer did send a truck and trailer to pick up the bike. A nice gesture since they are over 100 miles away. This time they replaced the purge valve. They said it failed to open 50% of the time during cycle testing. At this point, I am out of pocket almost $600. I will be happy if this fixes the problem. However, at this point I have only put on about 175 miles since picking it up.

That makes a lot more sense than replacing the battery did. I hope the new purge valve takes care of your issues.

P0174 CODE
I picked up the bike a little over a week ago, and after about 200 miles, the check engine light / P0174 code returned. The dealer picked up the bike again this morning.

Tell the dealer to replace the vacuum lines and that may solve the problem.

Right - surprised they hadn't done that yet. Vacuum lines to the MAP sensor. Left side of throttle bodies. That should point them in the right direction. Also a general inspection for vacuum leaks. The rear cylinder runs with less margin to the limit due to the much shorter header length. A healthy fuel injector cleaning is also effective. Techron, Seafoam, B-12. A canisterectomy will eliminate any interference from the purge valve system, but you'd have to do that yourself. In some rare instances on the 2012, a rear cylinder fuel injector replacement was the cure. Less expensive than a full blown throttle body.

I think it was sold. I got a frantic call from their business mgr. about three weeks later asking for the title, which surprised me, since I had signed the official ADOT power of attorney documents when the deal was done. Anyway, I hope the new owner has better luck than I did. It was a beautiful bike with less than 4K miles. Maybe since the dealer had it for three plus weeks after I traded it, they were able to spend more time diagnosing the problem without the pressure of a customer waiting.
