This post will cover the complete Yamaha Waverunner fault code list so you can troubleshoot your jet-ski. We are continuing to add to this list as new wave runners come onto the market with updated codes.
This fault code list is for the Yamaha Waverunner VXS VX1800 but will cover most Waverunner models on the market as the codes are the same or similar.

How to read and clear Yamaha Waverunner fault codes?
The Yamaha Waverunner will only give you the ability to read one code at a time. The following plug-in scanning tools can help you diagnose in more detail the problem with your Waverunner. I use the CandooPro myself and it is an amazing piece of hardware that supports Yamaha, and Sea-doo Jet-skis.
- Yamaha Diagnostic Software (YDIS)
- Marine Engine Diagnostic System (MEDS)
- Candoo Pro
These 3 code reading tools will give you the ability to read real-time data about your Yamaha Waverunner. They are perfect to reset fault codes and will enable you to fault find quickly. Well worth the investment if you do your own servicing and maintenance.
How do you check the codes on a Yamaha WaveRunner?
You can check the codes on a Yamaha WaveRunner by starting the engine and viewing the error code displayed on the display. You can also check previous error codes by pressing and holding the “Hour/Volt select” button for 8 seconds with the engine running.
On FX cruiser and high output Waverunners simultaneously press the two buttons “Hour/Volt & Speed/RPM” for 8 seconds. You can then check the error code indicated on the multifunction meter.

Yamaha Waverunner code reset
1. You first need to correct the problem that is causing the fault code to show up.
2. Start the Yamaha Waverunner up again and it will beep but won’t show a code (to get the code simply turn it off and it will be displayed, if not showing a code then the problem is gone) this will let know the CPU all is good.
3. You then need to turn it off, and wait 60sec. After the display goes blank and then the check engine light should be gone.
Yamaha Waverunner check engine light fix
If the engine check warning light stays on, disconnect the battery and touch the battery’s positive and negative terminals together. This will drain any power that may be stored in the ECU. This has reset the Waverunner warning engine light for me. Pressing the engine start button with the 12v battery may also clear the codes and warning light. Do it at your own risk.
Waverunner Engine Troubleshooting (diagnostic error code not detected)
If your starter motor does not operate and you get no fault codes check the following items.
- Yamaha Security System set to lock mode – Set the system is set to the unlock mode
- Discharged battery – Charge the battery or replace it.
- Loose connection of the battery terminal – Tighten the battery cables.
- Blown fuse – Replace
- Starter relay malfunction – Check/replace starter replay.
- Engine start switch malfunction – Test replace start switch.
- Short, open, or loose connection in starter motor circuit. Test and tighten cables.
- Starter motor malfunction – Remove test and replace.
- Stuck piston or crankshaft – Remove spark plugs, and try and turn over the engine.
- Stuck impeller – Remove the jammed object.
If your jet ski turns over but won’t start do these simple tests. Often it’s a simple battery problem that can bring up a whole heap of error codes.
Conclusion
I am constantly adding to this mega Yamaha Waverunner fault code list. If you discover any new error codes for your Jet-ski let me know and I will add them to the list.
I love to work on my personal watercraft and other vehicles as it saves me time and money. Teaching others how to fix faults on their Waverunners is a passion of mine. I love to stick my head in other people’s watercraft to try and work out why they are not running correctly. There is nothing worse than planning a day out on the water and the jet ski won’t start.
Good luck with it all and be safe out on the water.
I am a qualified Industrial Electrician for the past 20 years and I love to share my knowledge on home repair and maintenance jobs.
I love fast toys like Motorcycles, Cars, Jetskis, Boats, and Computers so writing about them is easy. Working on them is fun.
To keeps costs down I do all my own mods, repairs, and servicing. These skills I want to share with everyone. DIY is a skill everyone can learn.
I took a 2021 FX waverunner motor and put in a mini jet boat. I can’t get rid of the alarm and says Cruise assist err. I hooked up all of the original parts and system. Do you know what I might look into?
Hi my Yamaha 2021 is not starting will crank but won’t start I replaced the spark plugs and find out I’m not getting any spark on coils
Also I’m getting a code#49
Code 49 is over cooling. Sounds like a warranty issue as the temperature sensor must be reading too low out of spec. Check for disconneced or shorted out cooling temperature cables / probes.
What’s up Matt. I’m getting a 132 code on my 23 gp1800r. Trying to avoid going to the dealer. Is this something that would be covered under warranty? I only have about 20 hours on the ski. Where should I look first?
Code 132 is to do with the electronic throttle. If only 20 hours it should be covered under warranty. Check the APS output voltage
using the YDIS. Check the APS circuit for continuity eg throttle wires.
I am getting error code 17 (knock sensor). It is my understanding that this is only active when the engine is above 2,000 rpm. The code is intermittent, sometimes it shows up before I start the engine. When I check the resistance of the sensor it is within the normal range 504-616. Typically mine is 593 to 610. Is it possible/probable that the sensor is bad. I have had no degradation in engine performance.
