Hello All, I did a dumb thing. Considering there are 2 oil senders on the sled, a 2 wire and a 3 wire. With the latter being $400 from County Cat. I replaced the cheap one. Rode this week great for 150 miles the first day. Same the second. Third morning was much colder around 9. It started and idled to 160 degrees and shut off from the same oil pressure code. Started again and was fine. 10 miles later at around 75 to 80 the code came on and shut down the sled. Fied up with no code. .Under 70 It never did it again. Later in the day I tried the high end again and coded. Fine again under 70. Next morning it would code and never could get it warm enough to run. Sensor and oil pump are on the agenda when I get home. I will advise what I find. One question. Am I crazy to think I can change the pump in the sled. Thanks for reading another novel. Spaceman.

I don't have an actual sidewinder manual, but going through the Viper manual that I do have as well as many of the tech update materials that list fault tables, none of them have your 0524 in the table. They do have 0522 and 0523 which are both for the Oil pressure sensor, not switch. From that and the logical assumption 0524 would be related to 0522 and 0523, I'm pretty confident that the three wire sensor is the one that is being used for fault you are experiencing. I suspect the switch is only there to drive the dummy light on the CAT cluster.
I'm an engineer for a major engine manufacturer who deals with diagnostics daily and the way our oil pressure protection logic works is a table that varies minimum oil pressure with engine speed. The faster the engine is revving, the higher the oil pressure needs to be to avoid setting a fault. I'd bet that Yamaha is doing the same in your sidewinder ECU.
I still go back to my recommendation from last year and suggest you get an oil pressure guage on your engine so you KNOW it's a sensor problem vs a true lube system problem. There's a procedure in the Service Manual for testing this. I don't have it for a Sidewinder, but here's the one for a Viper for reference.
