Hi guys ad happy new year.
Spent about 4 hours jumping around in waves on the weekend and just as I was putting the ski on the trailer got an error code 23.
It still comes up after about 15 minutes running on the hose. I have a feeling I might have sucked u a bit of sand getting the kids on and off the ski at the beach but my search shows (on older ski's) that its an air temp sensor issue? Where is the sensor and what can I check on it?

Secondly, are there any places I should check if I've sucked up and sand or grit? Again, read on here to check the thermostat. Where abouts is it and is it easy to remove?
