Oil light/dipstick problem, please help out on ohm reading.

[jgustman]

My oil light keeps intermittently coming on and off. No problems on oil level, right at full with dipstick not threaded in. I tested the dipstick for continuity and got a steady reading at 6.7K ohms and 0 ohms the other way. Is this correct????

I just checked mine ,with dipstick in oil tank(full of oil) it reads no continuity.Took it out and it read really funny started out at 9. somthing and kept moving around usually dropping so I shook it and it went to .02 and stayed .I think the float inside wasnt sliding down to make good contact.

Another test, so bear with me...Ok, should the low oil light go off when unplugged from the dipstick? Mine doesn't. I have to shut the engine off and restart it to get the light to go out when unplugging the dipstick sensor. You can test this by pulling the dipstick out of the tank and plug it back into the sensor to trigger the low oil light, then unplug it again while engine is running and see if the light goes out. You will not lose any oil from the tank BTW. I'm trying to rule out the possibility that the guage cluster is hosed...

When I unplugged the dip stick with engine running and dipstick out of the tank,the light and oil emblem on speedo stay on,same as yours.

Thanks a bunch for checking, now I'm back to square one as to why the oil light keeps coming on. I'll go over the wiring tonight to try to find something wrong, then back to the dealer it goes before my warranty is up. Problem is, how can they fix the problem it if it can be reproduced consistently.

Wher are you located?Seems to me it must be the dipstick is the cause,maybee some body on here lives close to you and would let you try their dipstick.

That doesnt sound quite right does it.

No it sure doesnt Steve. but a good idea nonetheless.

 

[jgustman]

Nobody I know of around here to swap with, they might get a little defensive if I ask to use their dipstick I went over the wiring I and do not see a problem. I re-tested the dipstick with the ohm meter and still see eratic readings in the down position. ohm readings seem to jump all over the place when there is continuity...Shouldn't the ohm reading remain constant when testing???

 

[suprfst]

Mine stayed consistant only after shaking float down.Ohms were erattic before shaking.Seems like it would be a problem with the float on yours.If the float is made of metal (which it probaply is because it has to make contact) it could have a small hole worn into it and be getting oil inside thus floating lower and making contact in the bumps and causing your light to flicker.If it had a big enough hole it would be saturated and always flickering.Just my guess.

 

[jgustman]

The low oil light and warning light both come on and stay on, they never flicker. You can shut it down and restart, sometimes it goes out, sometimes it stays on. No rhyme or reason to any of it, it doesn't seem to make a difference what it does, even if you take the dipstick out and shake it around, put it back and it may work for a mile or work all afternoon before the light comes back on. It's going to the dealer tonight. I'm going to check the startup procedure for which lights should light and then go out upon startup. I'm thought I was only seeing the engine light and warning light upon startup, I think...Have to double check...I thought all the lights (enging, temp, low oil, warning light) in the display were suppose to light up initially upon startup???Do you know?

 

[suprfst]

On mine the outer two lights come on at startup as well as all of the Icons in the led portion of the speedo.Middle light doesnt light up.

I had the same problem and just got a new dip stick and problem solved.
