Default Check Engine on Two F250s

I went out to start my engines (twin Yamaha F250s) today and I received a check engine message and a loud alarm on both of them at the same time. They were fine when I last used them last weekend. Any ideas on what could cause both to have an issue at the same time? It looks like the oil pressure may be a little low but it is always on the low side. The amount of oil in each is way above the low line. Thanks in advance for any help.
