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 electrical shorts.

2. Check and Replace Oil

Sub-steps:
1. Remove the oil filler cap and check the oil level with the dipstick.
2. If low, add the correct oil type (5W-20) as specified in the owner's manual.
3. If oil is dirty or contaminated, proceed to drain and replace the oil.
4. Place a drain pan under the oil pan and remove the oil drain plug. Allow old oil to completely drain.
5. Replace the oil drain plug and torque it to 20 lb-ft.
6. Refill the engine with new oil through the oil filler cap.

3. Replace Oil Pressure Sending Unit

Tools Required: Socket set, torque wrench.
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 socket to remove the sending unit.
4. Install the new sending unit, torquing it to manufacturer specifications.
5. Reconnect the electrical connector.

4. Inspect and Replace Oil Pump (if necessary)

Tools Required: Socket set, oil pump removal tool (if applicable).
Sub-steps:
1. Remove the oil pan by unbolting it and ensuring the gasket is not damaged.
2. Remove the oil pump from its housing (may require timing chain/belt removal).
3. Inspect the oil pump for wear or damage and replace if necessary.
4. Install the new oil pump and reassemble components in reverse order.
5. Replace the oil pan with a new gasket and torque bolts to specifications.
