Code P1520 Engine Oil Pressure Switch Circuit

[KRK1]

Has anyone changed the pressure switch that can give me some direction on how to get at it. Can the switch alone be removed or does the part it threads into held on to the engine block by two cap screws need to be removed to replace the switch? Help appreciated! Thanks!

Its at the bottom of the motor on back side under oil filter, you can see it between the clutches. Removing clutches and the lower will help get at it. I believe its threaded into the play that mounted to the block. I have seen them toss code and just need the connector cleaned.

It's threaded into that block. But you'll need a special socket.

Okay guys thank you! Will check connector before removing the switch.

Changed switch. Easy to do through lower access panel. Two screws hold the part the switch is threaded into. Unplug both the switch and the other plug for the regulator and remove the part, changed out the switch, reinstall. Standard deep well 24mm socket to remove switch. The part holding the switch has an o-ring seal that has little keepers holding it in place so it stayed put nicely throughput the process. Cleaned some sludge out of the port to the switch which may have been the reason it coded?...but I put a new one in to be safe. Fired up and code cleared immediately. Got the replacement switch from NAPA 25 bucks. Over $100 on Country Cat website lol!
