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 ensure safety while working on electrical components.

2. Change Engine Oil and Filter

Drain the Old Oil
- Place an oil catch pan under the oil pan.
- Remove the drain plug using a socket wrench; allow the oil to fully drain.
- Reinstall the drain plug and torque to manufacturer specifications (typically around 20 ft-lbs).
Replace Oil Filter
- Locate the oil filter and use an oil filter wrench to remove it.
- Apply a thin layer of new oil to the gasket of the new oil filter.
- Install the new oil filter by hand until snug, then tighten according to the manufacturer’s specifications (usually 3/4 turn after the gasket contacts the mounting surface).
Refill Engine with New Oil
- Remove the oil fill cap and pour in new engine oil as specified in the owner's manual (typically 5W-20 or 0W-20).
- Replace the oil fill cap securely.

3. Replace Oil Pressure Sending Unit (if necessary)

Locate the Oil Pressure Sending Unit
- Find the sending unit, typically located near the oil filter or engine block.
Remove the Sending Unit
- Disconnect the electrical connector.
- Use a socket wrench to remove the sending unit; be cautious of any residual oil.
Install New Sending Unit
- Apply Teflon tape to the threads of the new sending unit.
- Install the new sending unit and tighten it to the manufacturer's torque specification (generally around 15-20 ft-lbs).
- Reconnect the electrical connector.
