Viper oil pressure issue

[mysledblows]

looking for some ideas or if I'm heading in the right direction. 2017 viper - long story short - it and my wife went swimming on New Year's Day. Got them out, home, and dried out. After drying out, 4 oil changes, and a new key switch we appeared to be good to go. About 60 miles after the incident it is now throwing the low oil light and shutting down. Let it sit, restart, and might get 10 miles or 10 seconds before it happens again. Oil levels good, no leaks, etc... I'm leaning toward the pressure sensor. In looking at the online fiche it appears there are two of them. One is fairly cheap and the other not as cheap. Probably going to toss them both in unless someone has any good ideas. Thanks!

My MP has went for a paddle twice now and your issue never came up. I'm surprised your wife didn't tell you to sell it. Before replacing those sensors, especially the pricey one, try removing it and making dead sure it is absolutely dry. Maybe pop it in the oven for a couple hours at 150F.

i was going along the lines of what yukonmp is saying. i would take them off and throw them in a bag/bowl of rice if you do not find water in the connectors. did you pull all the connectors and wd40 them? a coating of di electric grease in the connectors would not hurt.

Was water in oil when you drained it?

When it went in it basically did a quarter roll into the lake. So the right half went in and the left side stayed above almost exactly down the middle. I took apart and cleaned everything that I thought was under. Apparently I missed one or didn't get it good enough.

Yes the oil had a little milkshake look to it. After the second change it was pretty much back to oil, the third one looked good, and I did it one more time just to be sure since oil is cheap compared to motor parts.

Must be electrical. Ecu and all relays are on that si

Ecu and the relays are all on that side. Especially the relays are not waterproof. Wish you luck. Sounds like your doing best that can be done.

The depressing thing is that the first trip after going through stuff it ran/worked great until the key decided to stop going to the start position. That required a little thinking but a quick jump across the selinoid and we were rolling again just didn't shut it off till got home. Got that issue taken care of and thought we were good and then started with this new oil pressure bug. The funny thing is that if she stays at about a constant 35mph it will run basically forever but as soon as she blips the throttle or let's off it goes into limp and shuts down. Cycle the key and off she goes again. Eventually I'll get it sorted out but don't want to keep throwing parts at it. Thanks for the ideas, help, and encouragement.

Electrical issues especially intermittent are so frustrating. Remember mine that occurred twice 1500 mi apart? Still have a few hundred to go before I can say I surpassed the second time! Glad your wife is ok and still riding. No way mine would after dumping it in water. Pretty scary!

Electrical is great. Been fighting an intermittent shut off on the old apex for 2 years. Think I've finally got that licked. I remember your experience. Sucks when the issue only happens when it wants too. Wife says the water is really cold. Was just one of those freak things. She got lucky that I wasn't too far behind her and got her fished out from under the sled in a timely fashion. She wears good gear and it was a decent day temp wise and no wind so she stayed fairly comfortable once the initial shock wore off. Made a couple phone calls to get some help rounded up and got her to the public access on the lake where the kid picked her up with the truck and got her some dry clothes. She was a little hesitant the first trip after but seems no worse for wear. The sled remains a work in progress

Sounds like you married a good woman!
