Where is the oil sending unit on a car?
Find the oil sending unit, which will be screwed into the engine block near the oil filter, with a single wire attached to it. Turn the vehicle’s ignition switch to the “on” position, with the engine “off.” Unclasp the connector from the unit gently, using a pocket screwdriver if necessary.
When does a faulty oil pressure sending unit fail?
When it detects oil pressure in the vehicle, a switch trips and either the light shuts off, or the gauge becomes active. A faulty oil pressure sending unit can result in inaccurate oil pressure readings and warnings.
What to do if you lose your oil sending unit?
If not, the problem lies elsewhere in the circuit, rather than in the sending unit. Turn off the vehicle’s ignition and remove the sending unit with a socket, by turning counterclockwise. It is possible to lose a small amount of oil while doing this.

What is the oil pressure switch on a GMC Yukon?
Some of the company’s vehicles utilize a 5.3-liter V8 engine, including the GMC Yukon, GMC Sierra, Chevrolet Suburban and Chevrolet Silverado. The oil pressure sending unit, also called an oil pressure switch, is a component of the engine mechanical system. The oil pressure switch monitors changes in the oil pressure.
Can you replace an oil pressure sending unit?
An oil pressure sending unit is not hard to replace, and for most car makes and models, it is inexpensive as well. In fact, replacing a sending a unit is something most DIYers can try for themselves.
What should the PSI be on an oil sending unit?
Turn on the vehicle and drive it around the block a couple times, while observing the tester gauge. A normal range is typically from 40 to 60 pounds per square inch (psi), depending on the rate of acceleration. If readings are within this range and the previous test didn’t indicate a problem elsewhere in the circuit, replace the oil sending unit.
