    oil pressure switch

    hey guys. i got a code for oil pressure switch. i see the bosch part # 420856532 (2007 rxt) but no one here in town has the part. is there either a car application that this is used in or alternate part number that this would cross reference with?

    thanks

    yep. ski has been down for almost 2 years and finally got it back up. given the difficult location i changed my crank position sensor, but not oil pressure switch.... wish i did. don't have a seadoo dealer here and was wondering if this part was also automotive. used the tecdoc app but this number could not be found in there.

    you get it only after WOT or all the time? it probably is sea doo specific, but you can grab it from the the GH OE store.

    Does it run okay but just throw a code? Or does it go limp?

    You can always either unplug it or jumper it as needed if you are confident in your oil pump. (For the weekend, I mean).

    Now I am not convinced it is the oil pressure switch. I put a switch from a functioning ski, same po 1520 then limp mode. I then switched another engine harness figuring it was electrical and the same thing happened. Any suggestions? Possible oil pressure regulator?

    Ski was sitting for about 2 years or so. 2007 rxt

    Found out the problem!!!

    Hey guys, I found out why I was getting the oil light code (po 1520).

    To find out the problem I ran a few tests. I changed the switch, and harness with the same oil light result.

    Put on oil pressure gauge and at idle and revving the oil psi remained at 31psi.

    Prior to tackle oil pressure regulator I looked at the oil filter and whalaa the darn filter (brand new less than 1 hr) looked like it imploded.

    See pics attached.

    This happen to anyone else before?Click image for larger version.
