The oil sending unit on a 2000 Dodge Dakota with a 3.9 engine is screwed into the engine block near the oil filter. It is a small device that will have a single wire attached to it. The oil-sending unit, also called an oil pressure sensor or switch, is used to control the oil indicator light or gauge in a vehicle. This indicator will then inform the driver of any problems there may be with the oil pressure. It is important to have a working oil sending unit as low oil pressure can lead to engine damage.

If you suspect that your oil-sending unit may not be working to its highest standard it is reasonably easy to test it yourself. Before you start you will need to make sure that you have an oil pressure sending unit socket, an oil pressure testing gauge, a ratchet, an adjustable wrench, a jumper wire with alligator clips, a pocket screwdriver and an electrical tape. Also make sure that you checked the condition and level of your oil and added any if you feel it is necessary. Double check that this hasn't solved the problem before you start.

• Locate the oil sending unit and unclasp the connector. If your vehicle uses a light, attach a jumper wire to the connector and the negative battery terminal. The light should then come on. If it doesn't, the problem lies elsewhere on the circuit.
• Switch off the ignition and remove the oil sending unit. Next, screw in the manual testing gauge and route the rest of it and hose into the driver's side of the cabin. Tape the gauge to the inside of the windshield so that it can be read later.
• Turn on the vehicle and drive it around a few times and observe the tester gauge. Typically it should read 40 to 60 pounds per square inch. If the readings are within this range and a problem didn't show up else where on the circuit then replace the oil sending unit.

If you are having trouble locating your oil sending unit, consult your vehicle's manual or seek the advice from a garage.
