In this video I demonstrate the factory directed procedure to test the input and output voltages for the Mikuni fly-by-wire 60mm throttle body on the 2022+ Kawasaki Ultra 310 Jet Ski. The TPS Throttle Position Sensor is integrated into the throttle body.
If you are throwing a code, or even if you are not throwing a code, but are having an unexplained hesitation or stumble on your Jet Ski, this could be the reason!

You do better than anyone that ever taught me a school. I don’t even own a Kawi but your tutorials are great and always worth a watch. Knowledge is KING!
I keep thinking I should get a new Yamaha 1.9 SVHO when they come out so I can do tutorials on those as well
@@JDsWaterWorld if you can afford the new 1.9 SVHO I’m sure it would be worth while to do.
I’m keen to see that Kawi hit 500plus hours and what it takes to get it there.
I do a heap of hours on my skis that’s why I just go for the 1.8 HO engines for the last 8 years so simple and easy to maintain.
JD, thank you again sir for another priceless deposit into the Kawi bank of knowledge!
Hahaha of course it was no problem at all!
Good job troubleshooting bro, it's important to have the service manual.
Well done and great job explaining it.
Thanks, it was pretty easy!
Thanks.
That sucks. Glad you figured it out. How's it running now?
It’s not, I still need to get a new throttle body lol
@@JDsWaterWorld I hope the warranty covers this. 1K for a new TB!? This sucks man, not that many hours to be having this issue! You have some serious mechanical skills JD! Thanks for posting!
I have extended warranty exactly for reasons like this..I am going to dissect my old one and see if there’s a way to adjust/ repair it. There are hall sensor magnets inside that can break..this same TB is used on many Japanese cars
I looked and so far can not locate any new throttle bodies available for sale.
It’s the same one from 2014 to 2024. There are tons of them available for cheap.
Yo great Video When can I drop mine off
Hahah bring by anytime..and bring beer
Say less, I'll buy out everything they have in Costco.
Is the TPS adjustable? Sort of like the old Ford ones as they had a range you could turn it by loosening the screws.
Unfortunately, no. There is one bottom-end adjustment screw on this TB but it is not even used on the jet ski application- there is a plastic collar on the throttle plate shaft with a built in stop..this unit is not adjustable sadly
When i am in the FPM, when I full squeeze the throttle, their 1-2 second delay, normal?
Do you have a noticeable hesitation in acceleration?
@@JDsWaterWorld About 2 second delay so I am never the first starting in the race but fly by them once it kick in.
I am using the Kspeed ECU.
That is not normal…it should respond instantaneously when you hit the throttle. Only because I just had an issue with mine- check your throttle body and TPS…if you are 2022+ you should check KSRD trigger as well
@@JDsWaterWorld Will, hopefully we see and update video of this. Thanks.
That's crazy. I have the exact same issue. I changed everything including my fuel pump and I'm about to go lake test it
I do have a 2015 310 do you know if the test procedures are the same? I don't think I have the manual.
It’s a different test procedure because it’s a different ECU and yours also has a cable throttle with intermediate throttle position switch…but the throttle body is the same.
@@JDsWaterWorld yeah it's like a cable throttle that goes into a wire with the spring
Is that what you're talking about?
I turned on my ignition, and I pressed on the accelerating lever it was opening and closing the throttle normal it seemed like
@@JDsWaterWorld thanks for the reply!
You need to check the input and output voltage of the TPS just because it *looks* like it’s opening means nothing- you must do the test. Email me and I’ll send you copy of the service manual for your ski
@@JDsWaterWorld it's not allowing me to post my email on the comments. Is there any other way I could do that?
Kawasaki electronics probably aren't as good as Yamaha. I say this as a Kawasaki fan. A TPS should not be failing on a 2 year old ski. My first ride of the year should be this weekend
This is actually made by Mikuni, if anything they are to blame…it seems that post covid Mikuni switched production from Japan to China…
