Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shocks.

2. Change Engine Oil and Filter

Tools Required: Socket set, oil filter wrench, oil catch pan, funnel, torque wrench.
Remove the oil drain plug using a socket wrench and drain the old oil into the catch pan.
Replace the oil filter using an oil filter wrench, ensuring to lubricate the rubber O-ring on the new filter with a bit of new oil.
Reinstall the oil drain plug and torque to manufacturer specifications (typically around 30 ft-lbs).
Fill the engine with the appropriate type and amount of new oil (typically 0W-20 for Camry), using the funnel.
Recheck the oil level with the dipstick.

3. Replace Oil Pressure Sending Unit

Tools Required: Socket set, wrench set.
Locate the oil pressure sending unit, usually near the oil filter.
Disconnect the electrical connector and remove the sending unit with a socket wrench.
Install the new oil pressure sending unit and torque to specifications.
Reconnect the electrical connector.

4. Inspect and Replace Oil Pump (if necessary)

Tools Required: Full socket set, torque wrench, gasket scraper.
If the oil pump is faulty, drain the oil again and remove the oil pan by unbolting it from the engine.
Remove the oil pump from its mounting location.
Install the new oil pump, ensuring to use a new gasket and torque to specifications.
Reinstall the oil pan and refill the engine with oil.
