2002 Virage i 800 direct

[brian1965]

Hello everyone:

I have (2) 2020 Virage i 800 direct PWC. I have a couple of question, if anyone could be so kind as to answer.

Questions:

1) The first is one of the PWC has a blinking check engine light, I know it is the exhaust temperature sensor gone bad as I found it laying in bottom of jet ski hull. I was wondering how do I get rid of the check engine and red blinking light permanently for this issue?

2) The other PWC was running fine, put up 2 weeks ago, when went to start will not start? It has new plugs and battery. It is getting spark and the plugs have fuel on them, not sure what is going on. If anyone has suggestions, insights, or experience with this type of issue, I would appreciate your input.

Both PWC have less than 75 hours on them, they don't get used much. Few times a year. I am second owner bought them 10 years ago with 12 hours on them from an older couple who never used them. They look like new, I have had EMM rebuilt in past.

Thanks in advance.

1) You will want to replace the exhaust temperature sensor. But are you sure that's what you are referring to, vs the water injection solenoid?

2) You should swap EMMs to see if the "no start" follows the EMM

It probably the water injector solenoid, it is a wired valve hooked to a grey plastic block that mounts on front left of exhaust.

I dont have an extra EMM to swap it with to see if the no start goes away. I could probably remove it from the other running polaris?

Also I have found 2 cycle oil in bottom of hull, could that be from the solenoid being off exhaust?

[HiPeRcO]

You can and should swap EMMs between the machine, yes.

The oil in the hull is likely from it leaking out of the oil tank at the sending unit connection (a common problem). O-ring(s) and a hose clamp will fix that.

The solenoid does not connect to the exhaust. Its purpose is to inject water into the system for emissions purposes. It can be deleted (with proper disposition of the water lines etc) and bypassed with a resistor to make the EMM happy.

Thank you HiPeRco
I will swap out EMM when I head back to northern Michigan cabin and I am able to get to it. If it is EMM, I will send to you to rebuild. Is there instructions on by passing solenoid for exhaust?
If the swap out on EMM doesn't work, any other suggestions? Thanks

K447 has details on eliminating the water injection solenoid on his info pages:

Follow HiPeRcO suggestion on swapping the EMMs, first. They are in an awful location on the 2002s. Be careful working on the EMM mounting bracket, it has sharp edges. Only rune the ski long enough to verify if the issue is with it or not. The injector flow characteristics are programmed into the EMM. So having the two mis-matched can lead to engine damage with prolonged operation

The solenoid does - connect to the exhaust. Its purpose is to inject water into the system for emissions purposes.

It can be deleted (with proper disposition of the water lines, etc) and bypassed with a resistor to make the EMM happy.

The water that flows through the factory emissions solenoid goes directly into the exhaust gasses cavity inside the exhaust pipe.

If the solenoid is disconnected from the (small) exhaust pipe then the exhaust pipe fitting must be capped, otherwise exhaust gasses will flow out of the fitting and into the hull.
