Ford - Taurus :: Oil Pressure Light Comes On When Engine Heats Up And RPM Fall Below 1500 Or At Idle
Dec 12, 2011
I have a 2000 Ford Taurus V6 DOHC w/170K miles. When engine heats up, oil pressure light comes on, but only when RPM fall below 1500 or at idle. There is a burnt smell sometimes after driving the car. I do not see froth or coolant in the oil. Car burns a little oil, but no more than it has been for the last 50K miles. Just had oil and filter changed 300 miles ago; I was using 10W-30 but I believe the mechanic used 5W-30. (Also, if I drive more than 45 minutes, the "low coolant" light comes on-- however, the engine is not overheating, and the radiator/reservoir are full.) What part(s) I should order first? Oil pressure sensor? Oil pump? (If at all possible, I need to repair myself, as I simply cannot afford my mechanic's hourly rates right now.)

2004 1500 5.3 low oil pressure after using Lucas engine stop leak. No pressure at idle just below 40 when driving. Replace the sending unit and pressure improved for about a day. Just had a manual pressure gauge hooked up and it shows the same as cluster. No engine noise at all. I was informed that using Seafoam or another solvent could loosen up build up and cause damage. Trying to find out if using an engine flush machine may support. I am assuming that the cause of the low oil pressure is due to build up from using several qt of the stop leak over a four months. I am the only owner and I have always changed the oil according to schedule and have always used Valvoline synthetic.

Gauge/Sensor Problem ??? Great oil pressure on start up (40-60 PSI) but as car heats up, gauge SAYS pressure is dropping below 20 PSI. Dip stick says plenty of oil and filter is brand new. No knocking from valves either.

I have an 88 Chevy C1500. It started showing low oil pressure about a year ago and I went with a heavier oil and oil pressure go a bit better.
Just changed the oil and now, when I start the engine cold, I show normal oil pressure. As the engine temp increases, the oil pressure goes down. When engine is fully warm, oil pressure shows 0 and "check gauges" light comes on.
Decided to put even heavier oil in but guy at parts house said it was probably the sending unit, not a worn out engine. I tend to agree because I drove it more and never hear any ticking or valve noise. Too cheap to replace the sending unit.
From the symptoms above, does thus sound right? Could the sensor somehow fail as engine temperature increases? Everything I read says oil pump failure is very rare.

So the problems continue with the final payment of car. So now my oil pressure light comes on after driving for 10 minutes and sometimes goes off with i push in the clutch or keep it under 1500 rpms. Enough oil in car. What could be going on?

2005 Ford Taurus 3.0 engine. Only at idle has a popping noise out of throttle body. Found lots of people with same problem but no fixes.
I did find out noise goes away when unhook alternator wire and comes back when reattach. Found someone replaced there alternator and that didn't fix it either. I think its electrical?

I changed my plugs a few days ago on my 96' Taurus GL 3.0LI checked under my hood to check the recommended gap size and it said .42 to .46.. I went with .46. after putting them in i started the car up just fine, but later in the day i noticed when I came to a stop at a red light my car would sputter and my check engine light would start blinking. When I'd accelerate and drive it again everything would clear up and the light would stop blinking. I didn't change the wires, just the plugs in case you were wondering but I am unsure of how much that would influence my problem. Today after work i had a little trouble starting my car. After a few tries it started and my exhaust smelt rich in gasoline. Did i gap them too much? Should i get new plugs again and regap them? should i buy new wires also?Is my ignition coil going bad?

I am wondering what would cause the idle on a 1992 bmw 525i to drastically rise and fall continuously.

Have a 2001 CRV that is running really bad. It almost stalls when I put it in gear or even when the RPM's fall to idle. It is now throwing a p0172 code. I have a simple scan tool and verified the MAP reading and primary O2 voltages as suggested by the manual, both appeared to be normal. It seems all the symptoms point to valve clearance, however the valve were adjusted not 2000 miles ago by the dealer during the 150K service, and this issue has existed before and after that adjustment. I also cleaned the IAC screen with no changes.

My 2001 F-150 4.6L was hesitating around 1500 RPM and the check engine light was on, dealer said the oxygen sensors needed to be cleaned. Had the work done and the problem still exists, the check engine light intermittently came on. I tried 89 octane fuel and the check engine light is off and the engine runs smoothly. I'm just a weekend mechanic and can do mostly basic stuff but the only time I've come across something like this is when I accidentally put 87 octane in my bike.

How are they connected?

!995 honda accord, 5 speed. Idle is fine until the engine warms up, then fluctuates between 1500 to 2500 rpms. The idle control valve was cleaned- no change. Valve was also replaced -also with no change. Put old valve back on. Computer was disconnected after cleaning and also after each valve change.Would the next step be to remove and clean the fast idle thermo sensor? Also how do you check the coolant lines coming in. Anything else I would need to check, clean or replace.

The check engine light came on again after coming on about a week ago and then shutting of by itself. Everything seems to run normal with the car so I don't know if I should ignore the light and just keep driving or what. What would you do? My car is a 2011 Ford Taurus.

I have a 2001 ford taurus. just changed the engine with a used engine has 130k, did tuneup changing all spark plugs, wires and distributor cap. Also changed the 02 sensor upstream. And the check engine light remains on. if i start the car and it idles the check engine light flashes. but once i drive it, it just remains on. brought to the mechanic and he put on the machine and it reads that the problem is the 02 sensor upstream and the spark plugs misfiring. my mechanic is lost not sure what the problem is. someone told me it could be the manifold gaskets and pedlum gasket.

I have an old 2000 Ford Taurus that has been having some misfire issues. I replaced the wires and plugs about a year ago and hooray! it worked... until about a month ago when the check engine light came one. Misfire in cylinders 1 and 3... again. I ran some SeaFoam through and it did okay until this week, when the warning/flashing check engine light came back.
It is idling very hard (expected) and feels like it is trying to stall, even before the misfire came back (also to be expected??). So here is the question: is this a coil pack issue, or something more sinister (and expensive)?

This car has been giving me quite a bit of trouble lately. 04 Ford Taurus SES, about 97,000 miles on it. Just last weekend, it broke down on the highway. Found out the torque converter failed and needed to be replaced. I was suspecting that something was wrong with the transmission for a while now, because it would stutter sometimes when accelerating, and sometimes start shaking in the front when I turned it on. (It still stutters after having the torque converter replaced.)
Well now, a day after shelling out quite a bit of money to the dealer for this torque converter, the check engine light is on. I went to Autozone to check the codes, and they found P0300, P0305 (cylinder misfire) and P0316 ("crank sensor condition"). Is it possible the transmission is failing?? I found a bunch of complaints online about the transmission failing on the 04 Taurus. I'm trying to avoid more expensive repairs, but I don't want the car to break down on me again....
Also, a couple months ago, the check engine light went on a few times, but always went off within a day or two. Never did get it checked out because it didn't stay on long enough.

I have 104k miles on car, had tune up back in 09, new die hard battery from sears spring '10, just today my car started to shake when in idling, check engine light flashing. It seems to shake itself even while driving, when in idle it will then kill or die. Had radiator flushed January 2nd, 2011 due to heat not pumping through, still doesn't work (I know heater core) like it should. Finally the other problem is when I start & turn the car on it won't turn over-it wants to but takes a few tries like turning key each click like as if it were alternator, does sound like it would if it did turnover but like I said it takes a while & maybe will fire/catch. What the heck is going on? 2001 flex fuel as well but I only once put it in.

98 Taurus, 6cyl, 3.0L OHV, 184K miles. Check engine light is on and code reads "P0411 - secondary air injection system - incorrect flow". This is my son's hand me down car and has a rather large exhaust leak that I plan on fixing. Could this code be related ?? I found out that the CEL has been on for quite sometime now and the car is due for emissions testing (state inspection) in October.

I have a 1994 Saturn SL and ever since I bought it a few years ago it has been overheating in traffic but does just fine when I am driving without the stop and go. About a year ago 2 of the cylinders blew and I had to spend $700 to replace the now shot motor with a rebuilt one. Well the engine still heats up. I tried replacing the cooling sensor a few weeks ago and still no change. It really sucks because the only thing that keeps it from totally overheating is if I put the heater on full blast. And considering it's almost summer I really want to get this thing fixed. Using the A/C only makes it overheat worse, and will make my engine stop if I keep it running while stopped for a few minutes at a time like at a stop light.
