Question about 1995 Jaguar XJ6

1 Answer

Cannot find oil pressure switch or oil pressure gauge feed point. where are they? Oil pressure gauge not reading, oil light on continuous. Local garage confirms oil pressure okay, just no indication.

Oil light flashing not running rough.


Oil light flashing is a sign of low oil pressure. Either you have an oil sending unit reading incorrectly, or you have an actual oil pressure issue. You need to get a mechanical gauge hooked to the engine and get an accurate reading. If you have good pressure with the mechanical gauge then all you need is a new sending unit. If you have low oil pressure with the gauge...the good new would be that you sending unit is fine. The bad news would be that your engine needs opened up, at the very least the pan needs to come off to see if the sump tube is blocked and not allowing oil to feed the pump. But could be as bad as worn bearings and the need for an overhaul or replacement engine.

WHATS A OIL SENDING UNIT


it is a pressure sensitive unit in the side of the block that register oil pressure in the oil galleys of the engine
in vehicles with an oil light only it will switch off once a preset pressure is reached and turn back on when the oil pressure falls below that pressure
on other vehicles with an oil pressure gauge, it is a variable resistor unit that changes the resistance of the power from the gauge as the oil pressure fluctuates so altering the reading on the gauge
it is a different unit to an oil pressure sensor which conveys readings to the ECM

2001 f150 4.6 low oil pressure 2 or 3 minutes first start


Since you already know what your physical oil pressure is at idle I would try to get an accurate spec from Ford. if 10psi is normal the the problem is likely the switch or cluster.
If it is below spec it could be high mileage (normal bearing wear will lower idle pressure) a weak bypass spring in the pump, or a the wrong oil filter or oil.
If you are not hearing any "lifter clatter" or knocking when u start it, I wouldn't be too concerned about a bad pump or engine damage just yet.
Use only 5/30 or 10/30! anything thicker can cause cam damage due to oil starvation. Also going to long between oil changes can lower idle pressure as the oil looses viscosity and thins out.
According to factory wiring diagrams 2001 F150 does not have a pressure gauge , it has a warning light, however when I read the test procedure it talks about a gauge. either way, light or gauge, it uses a switch (not a sender) to signal the cluster that oil pressure is either above or below a certain value. again, I'm sorry, i don't know what that value is.
The instrument cluster receives ground through an oil pressure switch. When oil pressure is above a certain pressure the switch closes and the instrument cluster then turns out the light or indicates "normal" oil pressure. if the pressure is below a certain value the switch is open (the circuit to the cluster is not grounded) and the light will be on or the gauge will read no pressure.
The light or gauge is NOT directly controlled by the switch. If it has a gauge the gauge will show an increase in pressure when engine RPM increases (calculated by the cluster) it is not showing true pressure.
if your idle pressure is normal, you can test the by grounding the circuit at the switch, key on, if the light is out or the gauge reads normal the problem is the switch (assuming that physical pressure is above spec).
If the idle pressure is slightly below spec you could try an oil stabilizer like Lucas or STP and keep your oil change intervals to 3500 miles.
I hope this helps, feel free to contact me for more information

How can i fix the oil pump


see this tips and fix it. God bless you
The oil pump supplies oil to lubricate your engine. If the oil pump is worn or is not turning, the engine will suffer a loss of oil pressure, which may result in engine damage or engine failure.
The first sign of trouble may be a low oil pressure warning light, a drop in the normal reading on you oil pressure gauge (if your car has one), or the appearance of ticking or clattering sounds from your engine.
As a rule, most engines only need about 10 PSI of oil pressure for every 1,000 RPM of engine speed. Oil pressure will read higher than normal when a cold engine is first started because the oil is thick. Oil pressure will gradually drop as the engine warms up and the oil thins out. So normal oil pressure on a warm engine cruising down the highway is typically 30 PSI up to 45 PSI.
SYMPTOMS OF OIL PUMP TROUBLE
The first thing you should do if any of these symptoms occur is to stop your car, turn off the engine, let it sit for a few minutes, then check the oil level on the dipstick. If the oil level is at or below the ADD line, add a quart of oil to bring the level back up to the full mark. Add as much oil as is needed to raise the level to the full mark. Then restart the engine. If the warning light remains on, or the oil pressure reading does not climb back up to its normal range, or the engine noise does not go away, you may have a bad oil pump.
The other possibilities include a bad oil pressure sending unit, or a problem with the oil pressure warning light circuit or oil pressure gauge.
OIL PRESSURE SENDING UNIT
If the engine is NOT making any unusual noises and seems to be running normally, and the oil level on the dipstick is FULL, but you are still getting a low oil pressure warning light or low gauge reading, the fault could be a bad oil pressure sending unit.
The oil pressure sending unit is mounted on the engine block. On some applications, there is a spring-loaded pressure-sensitive diaphragm with a switch inside the sending unit. This switch completes the circuit to the low oil pressure warning light if oil pressure drops below a certain threshold. The unit may stop working if the diaphragm inside fails, if the switch is stuck, if the small hole that allows oil to enter the sending unit becomes plugged, if there is a loose, corroded or broken wiring connector at the sending unit, or there is a fault in the wiring circuit between the sending unit and warming light.
On vehicles that have an oil pressure gauge (electronic, not mechanical), the oil pressure sending unit has a small rheostat inside that sends a variable voltage signal to the oil pressure gauge when the diaphragm moves. A worn spot on the rheostat or any of the other problems just described for the simple pressure-type oil pressure switches can cause a problem.
FORD'S FAKE OIL PRESSURE GAUGE
On many Ford vehicles that were built from 1980 through the 1990s, the oil pressure sending unit has two switches, a low pressure and a high pressure. These vehicles also have an oil pressure gauge, but the reading on the gauge is not a true indication of real oil pressure. As long as the pressure to the sending unit is between high and low, the gauge will read normal. If oil pressure drops and trips the low pressure switch, the dash gauge will now read low. Or, if oil pressure goes up and trips the high switch inside the sending unit, the dash gauge will read high. Consequently, don't rely on the oil pressure gauge for an accurate reading in these vehicles. It is only a gross indication if the oil pressure is low, normal or high.
OIL GAUGE PROBLEMS
If the engine is NOT making any unusual noises and seems to be running normally, the oil level on the dipstick is FULL, and you have replaced the oil pressure sending unit but are still getting a low oil pressure reading on the dash gauge, the fault could be in the wiring circuit between the sending unit and gauge, or the gauge itself might be bad.
Check the wiring connections on both ends as well as wiring continuity between the sending unit and gauge. If no wiring faults are found, hook up a pressure gauge directly to the oil pressure port on the engine and check oil pressure with the engine running. If the engine-mounted gauge shows normal oil pressure but the dash gauge is reading low, the problem is a bad dash gauge.
On the other hand, if the engine-mounted pressure gauge reads low and you have done all of the above, chances are the oil pump is worn, or it is not picking up enough oil because of a restriction or blockage in the pickup screen in the bottom of the crankcase.
OIL PUMP PICKUP PROBLEMS
The pickup tube has a screen on the end to prevent large chunks of anything bad that ends up in the crankcase from being sucked into the pump. But we are talking BIG chunks of debris, not normal wear particles or carbon or dust or other microscopic-sized abrasive particles that can cause pump wear over time.

2000 Grand Cherokee V8: Cold start Oil Pressure is good at 600 rpm. Gauge drops to 0 in 2/10 mile as rpm increases to 2000. Warning light and bell comes on. Gauge varies between 0 and 40 depending on...


Replace the oil pressure sending unit its giveing a false reading . The problem is when the engine is cold the oil pressure is low and it takes a little time to build up whem cranking the engine and that sends a signal to the computer PCM /VCM what ever but your 40 to 60 lbs oil pressure is graet its ideal .The unit switches when the oil pressure is high enough to trip the switch inside the sending unit and that is sent to the vehicle control module

Oil light flickers when in idle. Oil on dip stick measures fine.


install a mechanical guage to test the actual pressure, if its fine the sending unit is faulty, if nor remove the oil pan and check the oil pickup for blockage,

My stop light keeps coming up with the problem oil pressure,i have a golf gti turbo


Get the oil pressure tested with an outside gauge. If you run short of oil pressure, turbo and engine will suffer, as you know....

If you are actually short on pressure, you would need to investigate further, usually no good answers there....

But commonly a transducer fails and gives wrong readings, hope for this result

High oil pressure in my humer h2


First thing that i would reccomend is switching to 5w30 oil since this is what GM wants you to run in your hummer. Next i assume your gauge is pegged out and doesn't fluctuate. You are going to have to take your hummer down to the local dealer and have a computer hooked up to see if the gauge is bad or the oil pressure sender is bad, more than likely the sender. thanks for using fixya !! have a nice day

Oil gauge reading?????


okay if you look at the oil pressure gauge the is a mark right below the "o" in oil. once the car is fully warmed up, at idle the gauge should read a little before that mark. at full throttle the gauge should be around the mark to the left of the "H"
