Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery cable to ensure safety.

2. Check Oil Level

Remove the dipstick, clean it with a cloth, and reinsert it.
Pull it out again to check the oil level; top off with the correct type of oil if low (5W-20 recommended for the Ram 1500 DT).
Ensure the oil cap is securely closed.

3. Inspect and Replace Oil Pressure Sending Unit

Locate the oil pressure sending unit on the engine.
Disconnect the electrical connector from the sending unit.
Use a wrench to remove the sending unit from the engine.
Install the new sending unit and tighten to the manufacturer’s torque specification (typically around 15-25 ft-lbs).
Reconnect the electrical connector.

4. Replace Engine Oil and Filter (if necessary)

Drain the engine oil by removing the oil drain plug and allowing it to fully drain into a pan.
Replace the oil filter using an oil filter wrench; apply a thin layer of new oil to the gasket of the new filter before installation.
Reinstall the drain plug and tighten to specification (typically around 20-25 ft-lbs).
Fill the engine with the appropriate amount of new oil.

5. Final Checks

Reconnect the negative battery cable.
Start the engine and let it idle; check for oil leaks around the oil filter and sending unit.
Monitor the oil pressure warning light to ensure it remains off.
