Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on the vehicle.
Allow the engine to cool before starting any work.

2. Check and Replace Engine Oil

Remove the oil filler cap.
Drain the old oil using a wrench to remove the oil drain plug; allow it to fully drain into a suitable container.
Replace the oil filter using an oil filter wrench, ensuring a new gasket is used.
Refill the engine with the manufacturer's recommended oil grade (usually 0W-20 for the 2018-present Camry).
Replace the oil drain plug and torque to the manufacturer's specifications (typically around 30 ft-lbs).

3. Inspect and Replace Oil Pump (if necessary)

Remove any components obstructing access to the oil pump (e.g., timing cover).
Unbolt the oil pump from the engine block carefully.
Inspect the oil pump for damage or wear. Replace if necessary with a new OEM oil pump.
Reinstall the oil pump, ensuring all bolts are torqued to the specified values.

4. Verify Oil Pressure Sensor Functionality

Locate the oil pressure sensor and disconnect the electrical connector.
Remove the sensor using a socket wrench.
Test the sensor with a multimeter to ensure it operates within the specified range.
Replace if faulty, and reinstall it securely.
