Need to know where the fuse is for oil sending unit on a 1998 Buick Park Avenue with a 3800 v6


There is no fuse for the oil sending unit ! Oil lite on , gauge not working ? Do you know what PCM five volt reference voltage is ? The PCM - engine computer supply's a stable 5 volt voltage to engine sensors . The oil pressure sensor is one of these sensors .
Engine Oil Pressure Sensor
The engine oil pressure sensor is a solid state transducer. The engine oil pressure sensor sends oil pressure information to the PCM. The PCM then transmits the oil pressure information to the IPC via serial data.
Engine oil pressure is displayed on the scan tool in volts. A low voltage reading indicates low oil pressure. As the oil pressure increases, the voltage level also increases. The normal range of the engine oil level sensor signal voltage is 0.5 volts at 0 kPa (0 psi) to 4.5 volts at 883 kPa (128 psi).

What does low oil pressure on 2008 Chevy Impala 3.5 V6 LS


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.

96 Chevy blazer how do I get out of safe mode ran low on oil now runs an drives but won't let car go fast past 2000rpms


The computing system on your vehicle has no safe mode for running low on oil . The only thing that will happen is the check gauges light will come on.
The oil pressure gauge is an analog device that is located in the IPC. The oil pressure gauge is operated directly by the oil pressure sensor circuit. As the engine oil pressure changes, the resistance of the sensor and the current flow in the oil pressure gauge changes. The current flow in the oil pressure gauge causes the needle to move in order to appropriately display the engine oil pressure. A sensor resistance of 1ohms will display as 0 kPa (0 PSI) and a resistance of 88 ohms will display as 80 kPa (80 PSI ). The IPC also monitors the oil pressure sensor circuit and interprets the current flow in this circuit in order to determine when the engine oil pressure is too low. If the oil pressure is too low, the check gauges tell tale will turn on. The oil pressure sender is located on the left side of the 2.2L. The 4.3L engine, oil pressure sender is located at the top left side, near the distributor/high voltage switch.
Try disconnecting the battery cables an hold them together for ten minutes , reset ECM !

Replaced oil sensor light still comes on


MAY---May-be you really have low oil pressure.. The way this sensor works is when you turn off the engine it closes to ground.. and when you start the engine.. the oil pressure opens it and the light goes out.. SO.. if the wire going to it is grounded out somewhere between the sensor and the dash board the light will stay on.. 3 choices.. 1. bad sensor (even though you replaced it) 2. wire is shorted to ground.. remove wire from sensor while engine is running.. light should go out. 3. you actually have really low oil presure. next.. after you have exuasted #1-2. you can remove sensor and install a real oil pressure guage and see what the pressure really is.. If you have very low or no oil pressure..1. Check oil level.(probably should have done this first) 2.pull oil pan and replace oil pump.. while you are there check a main bearing and a rod bearing for wear.. worn out bearings will cause low oil pressure. If you have good oil pressure install the pressure guage permanetly and forget about light.

Oil pressure low stop engine and check guage


Fist check oil level, the sensor is a pressure switch worked by oil pressure, hopefully the sensor has gone faulty. The oil pressure needs checking, if the oil pump or relief valve has gone faulty, the engine is being starved of lubrication and is causing internal damage. It is advisable NOT to run the engine till the pressure has been checked. (hope it's the sensor)

Oil light keeps flashing, car full of oil


Low oil pressure could be the reason the oil light in your car will come on. Test your oil pressure. Without enough pressure, the oil will not reach necessary areas of the engine. The oil pressure sensor itself may sometimes become clogged with sludge from the engine, especially if the engine has not been properly maintained. A clogged oil sensor can give a false reading of low oil pressure, which will illuminate your oil light. So, check the oil pressure sensor light.

Car is knocking and was low on oil cold it be the knock sensor out no oiland water mix in the oil


did the oil light come on? it it did that means a low pressure situation which can cause con rod bearing damage. the knock sensor can cause that too.

We are trying to find out if my 1997 buick le sabre has an oil pan sensor or oil pressure sensor and where it is located at so that we can change out the oil pan


all car well have a oil pressure sensor, the oil pressure sensor is what lets you know, you have good oil pressure, if light comes on low oil pressure, need to turn off engine before major engine damage occurs, the oil pressure switch will be next to the oil filter, screw into the engine block, your car also has a oil pan sensor, called oil level sensor, that one screw into the side of the oil pan, it let you know when your some what low on oil.

Low oil pressure light comes on and i changed the sensor


does the oil pressure gauge show low oil pressure?is it low oil pressure light? or low oil light? 2 sensors on this vehicle.make sure you get a chevrolet oil sensor,aftermarket sensor do not do well,make sure your using 5w30 or 10w30 wieght oil,if you are putting out over 20 lbs at idle in gear,i see no problem,should go up to 40 or better on accel,if it is low oil pressure and the gauge conferms,possible engine wear
