Solution

1. Preparation

Gather necessary tools and parts.
Allow the engine to cool before starting the repair.
Disconnect the battery to prevent electrical issues.

2. Change Engine Oil and Filter

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Place an oil catch pan under the oil pan.
3. Remove the drain plug using a socket wrench and allow the old oil to completely drain.
4. Replace the oil filter using an oil filter wrench.
5. Install the drain plug with the specified torque (consult manual for exact value).
6. Refill the engine with the appropriate type and amount of new oil as specified in the owner's manual.

3. Inspect and Replace Oil Pressure Sending Unit

Sub-steps:
1. Locate the oil pressure sending unit (usually near the oil filter).
2. Disconnect the electrical connector from the sending unit.
3. Use a wrench to remove the old sending unit.
4. Apply thread sealant to the threads of the new sending unit and install it.
5. Reconnect the electrical connector securely.

4. Test Oil Pressure

Sub-steps:
1. Connect a mechanical oil pressure gauge to the oil pressure sender port.
2. Start the engine and monitor the oil pressure readings.
3. If readings are within normal range, remove the gauge and re-install the oil pressure sending unit.
