    I need the part number for the remote oil tank sensor switch. Got the dreaded 4 beep alarm and checked switch. Showing closed loop with full oil tank. Ran engine with it unplugged, no alarm. Engine is 98 200 opti #og752228. Thx

    Nope... really not even close.

    You can lookup PARTS for your engine on our website- see Rhonda's post, pinned at the top of the Forum for assistance with parts.

    I agree with Joe- better than 95% odds that it's the TANK.
