How much is a oil sending umit

Check ur fuses and connection goodluck

first need to buy oil pressure sending unit 3/8 deep socket remove oil pressure sending unit you need teflon tap sealer for oil sending unit threads.okay to replace oil pressure sending unit.you need safe raise support vechicle locate oil pressure sending unit next to the oil filter.disconnect oil pressure sending unit wire connector then use oil pressure sending unit 3/8 socket remove the sending unit.then take new oil pressure sending unit use teflon tape white plumbers tape or use thread sealer apply to the oil pressure sending unit threads then install new oil pressure sending unit and reconnect electrical connector to sending unit.then crank engine check for oil leak if all is good lower vechicle back to ground wait several minutes check engine oil level.you good to roll.

THE ENGINE IS GETTING OIL AS LONG AS IT IS JUST YOUR SENDING UNIT. THE SENDING UNIT JUST SENDS OIL PRESSURE READINGS TO YOUR GAUGE OR IF YOU HAVE AN IDIOT LIGHT IT KEEPS IT OFF AS LONG AS YOU HAVE PRESSURE.

The sending unit is a variable resistor. When the oil pressure is normal only a small amount of voltage goes to ground through the sending unit. As the oil pressure goes down, more voltage is shunted to ground reducing the sending unit voltage and causing the gauge to indicate a lower pressure. If the oil pressure falls very low or disappears the sending unit shunts all the voltage to ground which causes the dash indicator to show no oil pressure.
Now if the wire to the sending unit gets nicked, melted or cut and finds a short circuit to ground, or gets disconnected in a junction point between the gauge and the sending unit, you will get the same no oil pressure indication from the gauge.
Check you wiring for a short to ground or an open connection.

in order to check the oil pressure, you have to remove the oil sending unit, then screw in the adapter of the oil pressure gage, and then remove the start relay or fuel pump relay from the fuse and relay box, under the hood on the drivers side, and then crank the engine over 3-4 turns, and then record the oil pressure, and then disconnect the oil pressure gage, and then re install the oil sending unit, replace the start relay or fuel pump relay, and then start up the car, and check the oil sending unit , to make sure it is not leaking, if your oil pressure checks out within the specs, then you are fine, if it gives you a low reading, then you could have a bad oil sending unit , or a oil pump going bad on you. i would replace the sending unit first, then see what the gage shows.

IF OIL SENDING UNIT LEAKING OIL NEED REPLACING.WHEN INSTALLING NEW OIL SENDING UNIT.YOU CAN USE TEFLON PLUMBERS TAPE ON OIL SENDING UNIT THREADS BESURE WHEN INSTALLING NEW OIL SENDING UNIT.PUT TEFLON TAPE JUST A LITTLE ABOVE THE BOTTOM THREADS. SO YOUR OIL SENDING UNIT THREADS GET A GOOD GROUND FROM ENGINE BLOCK.SO IT WILL WORK CORRECTLY.

The oil pressure sending unit is located on the engine block, passenger side by the Distributor. Good luck and make sure you get the right sending unit, there is the simple unit that only turns on a low oil pressure light and the other will send signals to the oil pressure gauge.

The pressure sending unit is located on the passenger side rear of the engine just above and slightly to the left of the filter and filter housing.

The oil pressure sending unit is located behind the oil filter, Threaded into an aluminunm housing. It has wiring that plugs into the sending unit. The oil filter has to be removed and you will need a deep well socket and a 6 inch extension. Change the oil and the sending unit together.
