SOURCE: flashig oil light

You either have a loose/worn engine bearing or a worn out oil pump, do not drive the car this way, you will cause serious damage to the whole engine. A oil switch is for a light, it turns on the light when oil pressure falls below about 10 PSI, a sending unit is for a guage that shows oil pressure with a scale, it may have numbers on the guage or just green and red, or high and low.

SOURCE: oil pressure guage dropping

Sounds like the sensor is failing.Have oil pressure checked with a mechanical gage to confirm. A new sensor or wiring repair is allot cheaper then a new engine!!

SOURCE: 2002 Jeep Grand Cherokee 4.0L oil pressure gauge reading too high

if the gauge starts a 0 - goes to 1/2 , than full - sounds like gauge is OK - seems to me like the sending unit is bad - you could try removing the sender and trying to clean out the port with "brake clean", letting it dry than re-installing it. the pressure switch is still the least expensive place to start

Make sure the oil level is correct. If the engine bearings are getting worn, the oil pump is worn or it's screen plugged, that can cause low-RPM weak oil pressure. Try running with 'high mileage' oil at your next oil change and always replace the filter. At some point, you may need to consider overhauling or replacing the engine. Good luck!

Very low oil pressure


Check your oil level. If it's anything like my truck, then the oil pressure gauge is whack. It could also be your oil pump is going out, or a vacuum hose has broke or worn through.

2001 F150 pressure gauge reads zero and light comes on when slowing down to 1st gear and stopped, sometimes light and gauge goes off and pressure returns, but fluctuates...also when gas applied and vehicle...


I assume you mean "Oil" pressure...This is the first sign of the main bearings getting to the point of needing replacement. The fact that the pressure goes up when you accelerate tells me that the oil pump is working. There is just too much bearing clearance for the oil pump to keep enough volume flowing at idle to maintain pressure. In short, it's time for an overhaul. It will be less expensive if you do it now than if you wait until you spin a bearing and destroy a crankshaft, or put a rod through the side of the engine block.

The truck f 150 ford dont star was un used for long time aroun one yaer and now said check gauges what is that?


The check gauges light will come on when one of the gauges is not in a normal range, either low fuel, low oil pressure, over heating, or low battery. Since the truck sat for so long, my guess would be low battery.

Oil pressure gauge starts fluttering after truck is driven 15-20 miles and you pull up at stop light. As soon as you accelerate it stops ? oil pump going bad?


Could be oil pump, also could be sending unit. When did you last change oil, is oil low? If it's been a while try putting in high mileage oil with higher viscosity, 20w50 for example

2000 Ford F-150. The oil temp warning light came on and the oil pressure gauge dropped to zero. While accelerating, the pressure gauge goes back to normal and the warning light goes out. No drivability...

Ve a 2001 F150 that keeps losing oil pressure


could be but have you actually check the oil pressure

The oil pressure gauge on your dash is really just an warning light and you are not really looking at real oil pressure

Therefore you could have an electrical issue, mainly high resistance in the sender circuit that make the gauge read lower than actual

Low oil pressure


If low oil pressure is verifiable the only repair is replacement of the oil pump assembly.

Start by verifying oil pressure with a mechanical oil pressure gauge. If oil pressure is low then replace oil pump.
