Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical shorts.

2. Check and Replace Engine Oil

Sub-steps:
1. Remove the oil filler cap and check the oil level with a dipstick.
2. If oil is low, add the appropriate type of engine oil (5W-30 recommended for most Mustang engines).
3. If the oil is dirty or has not been changed for over 5,000 miles, proceed to change the oil.
4. Drain the old oil using a drain pan, remove the oil filter, and replace it with a new one.
5. Refill the engine with the correct amount of new oil and replace the oil filler cap.

3. Replace Oil Pressure Sending Unit

Sub-steps:
1. Locate the oil pressure sending unit (typically near the oil filter).
2. Disconnect the electrical connector from the sending unit.
3. Using a socket wrench, unscrew the old sending unit and replace it with a new one.
4. Reconnect the electrical connector and ensure it is secure.

4. Inspect and Replace Oil Pump (if necessary)

Sub-steps:
1. Remove the oil pan to access the oil pump (may require removing the transmission).
2. Inspect the oil pump for damage or wear.
3. If faulty, replace the oil pump with a new unit.
4. Reassemble the oil pan with a new gasket and torque to manufacturer specifications.
