Having the correct amount of oil pressure in your Jeep Cherokee is essential for keeping your engine running smoothly. An oil pressure sending unit is the main component responsible for monitoring and controlling this crucial element. It plays a major role in ensuring that enough lubrication is provided to all parts of the engine so they can function properly. In this article, we’ll discuss how to maintain and check your Jeep Cherokee oil pressure sending unit so you can get the most out of it with minimal hassle.

What Is an Oil Pressure Sending Unit?

Maintaining the Jeep Cherokee Oil Pressure Sending Unit An oil pressure sending unit is an electrical device attached to your Jeep’s engine block or cylinder head. It contains a switch that turns on when the engine’s internal components are under more stress than normal, indicating an increase in oil pressure. This switch then sends a signal to either a gauge or warning light on your Jeep’s dashboard, alerting you if something needs attention. As the oil pressure sending unit alerts you to any changes, it’s important to know what the normal oil pressure in a Jeep should be for accurate interpretation.

Benefits of an Oil Pressure Sending Unit

The presence of an oil pressure sending unit allows you to keep track of changes in oil pressure levels quickly and accurately without having to open the hood and physically check them yourself every time you drive it. Also, since these units are installed in the engine, you don’t have to worry about them becoming corroded or damaged due to exposure to the elements.

Symptoms That May Indicate a Problem with Your Oil Pressure Sending Unit

If your Jeep’s oil pressure sending unit is not working properly, you can expect several symptoms that may alert you of its malfunction. These include a drop in oil pressure readings (as indicated by your gauge or warning light), vibrations or noises coming from the engine, and decreased fuel economy. If you notice any of these signs, it’s best to take your vehicle in for service right away.

How to Check and Replace Your Oil Pressure Sending Unit

Performing regular checks and maintenance on your Jeep Cherokee’s oil pressure sending unit is important for ensuring it will work properly when needed. Here are some tips on how to check and replace your unit:

  • Inspect the wiring of the sending unit for any fraying or loose connections. If any are found, have them repaired as soon as possible.
  • Check the hoses that run from the sending unit for signs of wear or damage such as cracks, holes, or leaks. If any problems are found, replace the hose immediately.
  • Check the level of oil in your Jeep’s engine and top it up if necessary.
  • If your Jeep is showing signs of a malfunctioning oil pressure sending unit, consider replacing it with a new one.


Having an oil pressure sending unit installed in your Jeep Cherokee can be beneficial in making sure that the engine parts receive proper lubrication and don’t suffer from any damage due to low levels of oil pressure. However, it’s important to remember to check and maintain this unit regularly so you can get the most out of its performance and maximize your vehicle’s efficiency.
