fj09newbie Posted July 5, 2021 Share Posted July 5, 2021 Yes I have searched and found many, but none relating to my issue. If there is one, I am sorry I didn't find it. I have 2017 FJ09. 8k miles, all maintenance done at dealer so far since under warranty. Over the winter, My battery died, and would not charge, so I bought a new battery. I had emptied the gas tank so there was no gas in the tank. I changed the battery about a month ago, and have had it on a maintainer since. I filled it up today with 93 fuel, and went for a ride. I didn't notice utnil about 20 minutes in that my check engine light is on. It is running great, and can't tell any difference in idle, acceleration, or cruising at all from last fall. I have read a few other places that this could be from the battery change and could disappear after a couple cycles of heating up the bike, and it cooling down, so a couple of rides, but I didn't know if anyone else had experience with this.

skipperT Posted July 5, 2021 Share Posted July 5, 2021 Ok. Because you have a 2017 you’ll need to get the code erased at the dealer, or with a generic OBDII Automotive code reader and an adapter cable to go from the OBDII reader connector to the white Yamaha 4P diagnostic connector. You can try the key cycle/“light go away” method, the code is still in history and can be viewed later. Only certain malfunctions will allow the MIL light to go away this way however. -Skip 1 Link to comment Share on other sites More sharing options...

The dealer is closed today due to the holiday so I can't go in. is there a risk of riding it with the light on until I can get in there? Link to comment Share on other sites More sharing options...

Same if the abs/Tcs lights are on - you are riding without safety systems, so just bear that in mind. in your original question, you wanted to “operate the bike for several cycles to see if the MIL light would switch off. “That’s what I meant by “light go away”. This sometimes works on the automotive side, not necessarily with Powersports products. -S Link to comment Share on other sites More sharing options...
fj09newbie Posted July 7, 2021 Author Share Posted July 7, 2021 Right thank you. It isn't running any different than before. I will be putting in a call to the dealer today to get an appointment. Thank you for the insight and advice. Link to comment Share on other sites More sharing options...
Great Gonzo Posted July 28, 2021 Share Posted July 28, 2021 93 fuel??? I thought you are meant to use a higher octane? Link to comment Share on other sites More sharing options...

The consensus on this board is that, at least on the road when you're not at redline all the time, octane probably doesn't matter on this bike. I'm not recommending 87, but it probably won't hurt. 2. In the US, 93 is high octane. Some places only have 91 or 92. Link to comment Share on other sites More sharing options...
Great Gonzo Posted July 28, 2021 Share Posted July 28, 2021 Oh ok i didn’t know that. I think our regular fuel in the UK is 95 and our premium is 98+. im sure my handbook quotes to use premium fuel only. gonz. Link to comment Share on other sites More sharing options...
fj09newbie Posted August 18, 2021 Author Share Posted August 18, 2021 (edited) So, I just checked my 17 FJ09 and got a code of P2138 and beside it showed $07E8. Throttle / Pedal Position Sensor / Switch D / E Voltage Correlation. I didn't do anything to the bike except change the battery, and let it sit most of the winter. I am googling also, but wanted to see what you all thought. I am not sure what would cause this. Edited August 18, 2021 by fj09newbie Link to comment Share on other sites More sharing options...

I am googling also, but wanted to see what you all thought. I am not sure what would cause this. After changing the battery did you start and ride the bike to verify correct functionality prior to putting it away for the winter? The reason I ask is because the battery position can be confusing if you don't read the pos/neg symbol on the terminals, its actual fairly common for some to install it backward, even though it looks correct. If the polarity is reversed, you can spin the battery 180 degrees and then lay it on its right side and the terminal polarity will be correct. IF you installed the battery reversed chances are you probably blew a 1 or 2 fuses, that issue has been posted here several times. ***2015 Candy Red FJ-09*** Link to comment Share on other sites More sharing options...
fj09newbie Posted August 19, 2021 Author Share Posted August 19, 2021 I put it away before the battery went dead. The battery went dead over the winter storage. I didn't ride it enough. I changed it, started and let it run, and then rode it about a week or so later. that's when the light came on. Link to comment Share on other sites More sharing options...
