Oil pressure light/switch

[SHOSIG]

My rear heater hose blew apart Sunday, spraying antifreeze (hot), on the oil pressure switch, after I replaced the hose, my oil pressure light came on. I wiped off the sending unit and it went out. Shortly afterwards, the light came on again. I picked up a sender from YamahaSHO and put both senders on the ohmmeter. My old one read .06, the one I got from Jason read 1.6. I'm sure this would trigger the light. I installed the new sending unit and no light so far. I'm wanting to make sure that the difference in readout is the reason the light went on and not because of a oil pump. Thanks for any input.

you could test your oil pressure to be sure should be a minimum of 12.8 psi warm at idle

That would involve installing a gauge and a full sweep at that to be postive what pressure is actually being seen at idle.

If it is constantly testing bad on the ohmmeter, my guess is you fried the sensor when all the hot water hit it.

I think it is funny that we both blew the same hose in one week!

Just a question about the rear heater hose .

I have a leaking hose , Its to the right and behind the throttle body . it connects to the block ( i think) with rubber hose and hose clamp and has a crimped fitting after that .

Would that be the rear heater hose . Jst asking . I am waiting on my CD manual . And it would be nice to know the name of that hose . so i can order 1

I know .the manual would awnser that . but i have no manual yet

3/4" heater hose solves the problem...

just trying to help him he asked for ways to tell it was the sender and not the pump. so i gave him a way. installing a guage is easy as installing a new sender.

I understand that, but he is trying to troubleshoot the stock switch/sender. There is a little more work into wiring an external gauge than swapping out and existing switch. You'll need a 'tee' to keep your stock switch and have to run wire into the cabin and search for an ignition hot source and a lamp source. Running a mechanical gauge will require running tubing into the car for oil to make it to the gauge.

no i am talking about a oil pressure testing guage it screws right in where the sensor goes. it looks just like a fuel pressure tester. but made for testing oil pressure. you can get one from any part store.

just thought id post since i blew that heater hose w/ the crimped fitting on the block..man ive spent all night getting that sucker out. i just happened to have some 3/4 inch heater hose since it happened after all the auto parts stores had closed. i had to get that stupid pipe out though to cut the crimped end off..IMO that thing is a PITA!
