Question about 1987 Chrysler New Yorker

1 Answer

I have an 85 chrysler new yorker and even when I accelerate the oil pressure is low?

I can accelerate up the oil pressure stays in the low part. The mans voice doesn't say that it needs to be serviced, but it never goes any higher than low. Usually it would ride about mid-high oil pressure, depending my speed. Any ideas?

    The oil is between the fill line and the need to add. I had just driven 500 miles before and everything was normal. Nothing seems hot, no weird noises. My motor is really smooth also. Earlier in the day it would go from low to mid range but then just stuck on low. Not the red light low, just low. Is it possible the oil pressure sending unit is just old? i mean this weekend is the first time its really gotten cold at all.

    between the dots (add and full) is usually a half quart to make it full. Yes, you could just be getting a weak voltage to the sending unit. If your oil pump was bad, you would have noise, smells, and maybe a dead engine by now. I think you may be in good shape. you could also have a lot of sludge build up in the heads which would slow down the oil as it returns to the pan, which would cause a low pressure read on the gauge.

    So i'm going to add a little oil and see how it goes. Then if that doesnt work buy a oil pressure gauge to test the pressure. If the pressure is fine then i need an oil pressure sending unit. If its bad I need a new oil pump. Does that sound right? I dont know all that much about cars so i'm trying to make sure i keep mine running.

    I checked the oil pressure. It idles at 20 and when the engine is revved it goes to 41. So its no the oil pump. just the oil pressure sending unit.

    places sell flush chemicals, but all that does is move all the gunk to the oil pan for the pump to clog up with. It should be fine for now.

SOURCE: car dies suddenly while driving all speeds

Hi krh60, I would strongly recommend having the cps (cam positioning sensor) and the css (crank shaft sensor) checked immediately, both can cause your problem and both throw no codes when running, in early stages the vehicle may start again or it may not. Ford also has a cps problem on their 7.3's also see if Chrysler has a recall on these parts you may get lucky hope this helps good luck to you.

Could be a bad oil pressure switch, or a bad oil pump. Both will cause this issue. Hope it is the switch b/c the oil pump is a costly repair.

SOURCE: Can't find flasher for blinkers on a 92 Chrysler New Yorker.

If you have the Owners Manual for the car look up flasher and it will show you a diagram of the relays so that you know what you're looking for. I own a 1992 Chrysler New Yorker Fifth Avenue and the flasher relay is located right above your glove box on the passenger side. You have to unscrew the glovebox casing with a phillips screw driver. Once you have this unscrewed there are your fuses and two sets of relays. One relay set that you can see on the right side (this is not where the flasher relay is) and one that is up more in the dash and closer to the inside part of the car by the side of the air condition controls. This is where the flasher relay is located. You can slide the whole casing of relays up off of the metal hook that it is held on by, and then pull it down and out so that it is easier to work on. There should be two square relays and two circle relays. When holding the case of relays, the two square relays are on the left and the two circle relays are on the right, it will be the top right circle relay that is the flasher relay. This took me forever to find. I hope this helps all of you so that you don't have to rip your dash apart like I did.

More than likely the sending unit is not communicating with the fuel gauge so even when the tank is full the unit doesn't register it.There could be a short or a loose connection from the sending unit to the guage

Chrysler new yorker only low oil pressure


if you are full of oil, this could be as easy as an oil pressure sending unit, which you may see near the oil filter.

It could be an oil pump going bad, and you will be looking at a mechanic shop at that point.

I would check the connection of the oil pressure sending unit to make sure it's plugged in properly.

People have told me the pressure quit working after an oil change, and I found that in most cases, whoever changed the oil damaged that sensor.

Hook up a mechanical test gage to the oil pressure port where the oil pressure sender goes and verify the oil pressure is at least 20-30 pounds at idle engine hot. If the oil pressure checks ok on the test replace the oil pressure sender. You should be able to borrow this gage from Autozone or O'reilly auto parts with a deposit and a credit card.

Chrysler new yorker with a 3.0 liter v-6 engine burns and smells oil and stalls when hot. Can anything be done other than change the engine to fix or improve this problem?


Bad valve guides and seats were pretty common item on those 3.0L engines in those days. Caused oil to leak in beside guides and into cylinder, especially at idle, or after hard acceleration, then let off (highest vacuum ) when warm. If your handy at all, heads can be done pretty reasonably at engine shop, or even get a set of heads from newer engine, when problem was cured.

I think you have a suspect oil pressure sender unit. Replace it as they are cheap and need to be reliable and it will be cheaper than getting the oil pressure tested. If the light still stays on with the new sender you may have internal wear or a partial blockage. If the light stays on you need to have it urgently checked by a mechanic or you could risk serious engine damage.
