Posted just now Looks like the problem is solved! So, Amazon OBD II scanners can only get you so far... What looked like a TPS sensor gone bad actually turned out to be the APS sensor (Acceleration Position Sensor) instead, and it had to be calibrated with the Yamaha dealer tools for it to operate correctly. Recap: We originally replaced the TPS and did a throttle body sync (without the dealer tools), and bike had same issue. Replaced the APS and then a different issue - bike would act like it would start but wouldn't actually turn over, so my guy installed the original APS (thinking I could return the new one I just bought) and said probably needs further diagnostics form the dealer because they have specialty tools. He was right! Took it to the dealer, they hooked it up to the Yamaha Dealer tools that drills down further than my generic OBD II scanner and it said it was the APS, with a specific note saying it wasn't signaling to something, etc. (I forget the exact note). He took it off right in front of me, moved the guts with his finger and showed me the range of movement wasn't correct and couldn't even get to where it needed to be. He then hooked up the "New" APS I brought with me, moved the guts with his finger and showed me had the proper range and values like it should. He installed it, calibrated it, and bike issue is solved. When I asked him why it didn't work the first time we installed it, he said, "There is about a 40% change it'll work as-is, but they really need to be calibrated with the special Yamaha Dealer Diag tools." He did that, and it was fine. So it looks like there WAS an issue with my original APS, and the new one calibrated by the dealer with their special Yamaha Diag tools fixed it. - Paul

It's actually a T900GT, 2019. My apologies...

Well, add me to the list with the same exact problem. 2019 Tracer 900 GT. 11,000 trouble free miles. Flashed by Ivan, and also have a Rapid Bike RACE with auto blipper. Bike ran perfectly. Developed same issue as what's described here. No throttle when accelerating or sometimes coming to a stop...bike dies, check engine light comes on. It's VERY dangerous. My OBD2 scanner says the code is P2138. I look up on the internet. Says throttle position sensor. I bought a brand new TPS from Yamaha and had it installed. Rode the bike for an hour and went to my GF's house for dinner and it rode great. I left her house and it did the same issue on the way home. I was accelerating from about 50 to 70 mph in 5th gear. The bike started stumble a little bit and just shut off, I got off the highway coasted to the shoulder and the check engine light came on. Restarted no problem and road it home. Scan the code and again same code, throttle position sensor. What do I do at this point? Replace the acceleration position sensor on the throttle body? Or just replacing the entire throttle body which comes with new sensors?. Again, this bike has been perfect for the last 11,000 miles... Thoughts?

Thanks Skip! Is the calibration only something the dealer can do? Because my guy who installed the TPS sensor also sync'd the throttle bodies...and he knows Yamahas...used to be an engine builder for Graves Motorsports for like 10 years...

My bike is a T9GT as well...

Sold!

Good to know. I just went with this exact set up...installing it this week!

2019, but it just sold...

Hey everyone, the item just sold...

SOLD!!! Hey everyone! I got my stock seat recovered, so I'm selling my Official Yamaha Accessory Comfort Seat Set (Rider and Passenger) $200 Shipped. If interested, please email me at pgeldz@gmail.com

SOLD! Hey everyone! So I finally got around to building my 2019 Tracer 900 GT, and went with some Dymag forged aluminum wheels in Black because I didn't want the Blurple wheels anymore. No need for me to keep the OEM set up, so I'm selling them. $600, Located in Las Vegas. Complete with OEM tires, brake disks, spacers, and OEM sprocket and carrier. They have less than 5,000 miles on them. I did reuse the ABS rings though on the new wheels so they are missing those. Can ship within the US. If interested, please email me at pgeldz@gmail.com

Currently wearing the X-Lite X-903 with the Nolan BCOM comm system...love it!

I'm really liking the FIVE Gloves TFX1's...

I rode it!

Nice write up!

I just put a set of Dunlop Road smart 4's and LOVE them!!! Plenty of stick... They are new so not sure how long they last, but from everything I've read supposed to outlast the Pirelli Angel GT's and have more grip...

I just did Spiegler lines. Use them on all my builds. Definitely help a bit with lever feel...

I have the rear Heed bars for my Tenere 700 and love them!

The Five Gloves TFX1'a are very nice!

Thank you!

I"m here! LoL! In fact, I just took my Tracer 900GT on a nice ride over the weekend! Yes, it's true on the FZ07.org forum, there is a group buy going on, and some of those items also fit the Tracer 900. Some good deals to be had for sure! - Paul
