Solution

1. Preparation

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

2. Check and Top Off Engine Oil

Sub-steps:
1. Remove the dipstick and wipe it clean.
2. Reinsert the dipstick and remove it again to check the oil level.
3. If low, add the appropriate type and amount of engine oil as specified in the owner's manual (typically 0W-20 for the Camry).
Tools Required: Oil funnel
Safety Warnings: Allow the engine to cool down before checking oil levels to avoid burns.

3. Replace Oil Filter

Sub-steps:
1. Locate the oil filter and prepare for oil spillage.
2. Use an oil filter wrench to remove the old oil filter.
3. Apply a thin layer of clean oil to the rubber gasket of the new filter.
4. Install the new filter by hand until it is snug, then tighten according to specifications (usually 3/4 turn after the gasket makes contact).
Tools Required: Oil filter wrench, oil catch pan
Safety Warnings: Ensure the vehicle is securely lifted if working underneath.

4. Replace Oil Pressure Sending Unit

Sub-steps:
1. Locate the oil pressure sending unit, typically found near the oil filter.
2. Disconnect the electrical connector from the unit.
3. Remove the sending unit using a socket (usually 1-inch).
4. Install the new sending unit and reconnect the electrical connector.
Tools Required: Socket set
Safety Warnings: Ensure the engine is cool to avoid burns.

5. Perform an Oil Change (if necessary)

Sub-steps:
1. Drain the old engine oil by removing the oil drain plug (use an oil catch pan).
2. Replace the oil drain plug and torque it to specifications (typically 25 ft-lbs).
3. Refill with the correct amount of new engine oil through the oil fill cap.
Tools Required: Socket set, oil catch pan
Safety Warnings: Allow engine to cool before draining oil.
