Pressure of 212 over 103, what does it mean - Cars & Trucks

Oil light is rather important it goes out if oil pressure is good comes on if oil pressure is low when it comes on damage is expected with continued operation like wearing of main bearings and pistons and cylinders can lead to a engine rebuild

When you say oil in car what do you mean? If you mean in the water reservoir that could mean the head gasket.

Do you mean what causes low oil pressure? This is a very reliable engine for the most part. If the oil light is on or gauge is reading low, have the oil pressure sensor inspected for failure. These sensors do go bad.

It's a sensor that goes off when your tire pressure is too low or too high. Check the air pressure.

depends if it is good or bad. the pressure regulator is to be operated by pressure. depending on the manufacturers fuel pressure, it should only be open when that amount of pressure is applied. if you removed it and can easily blow through it, then most likely the regulator is stuck open causing it to flood the engine with fuel. not being able to blow through it could mean its properly working, or it could mean its seized shut. but usually when they go bad, they go bad by dumping too much fuel which means you blow through it easy

blowing blue smoke means burning oil. a compression test can help pin point where oil is leaking in the cylinder(s). remove all of the spark plugs and check the compression pressures of each cylinder. If the lowest pressure reading is within 10%-15%, you can assume that the lower half of the engine is Ok. one at a time, squirt a few drops of engine oil in the spark plug hole and check the compression pressures again. a big increase in pressure means poor piston rings. very little or no difference in pressure means valve train leaks. like valve guides or seals.

it means the oil pressure is low and may be low enough to damage the engine if you keep drving/running the engine. it would help if you could tell us the actual oil pressure, engine and mileage . basically, the oil pressure may be low enough to wreck your engine, then again it may be bs......

Both codes P0191 and P0193 on Ford means Fuel Rail Pressure Sensor Circuit High Conditions. That means that the PCM detected that the FRP sensor signal was more than 4.5v.

Possible causes:
* FRP signal shorted to VREF or VPWR.
* FRP signal open
* Damaged FRP sensor.
* Damaged PCM.

Check ground connections.

usually that could mean a failing oil pump....or a clogged pickup in the oil pan, could also mean you have a leak somewhere. the car shutsoff because it protects itself from killn itself
