Solution

1. Preparation

Tools Required: OBD-II scanner, mechanical oil pressure gauge, socket set, oil filter wrench, oil catch pan.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Change Oil and Filter

Sub-steps:
1. Drain the Oil: Place an oil catch pan under the oil pan. Remove the oil drain plug using a socket wrench and allow the old oil to drain completely.
2. Remove Oil Filter: Use the oil filter wrench to remove the old oil filter. Make sure to lubricate the rubber gasket of the new filter with a bit of fresh oil before installation.
3. Install New Oil Filter: Install the new oil filter by hand, tightening it until snug.
4. Replace Drain Plug: Reinstall and tighten the oil drain plug to the manufacturer’s specified torque (typically around 30-40 ft-lbs).
5. Add New Oil: Pour the appropriate type and amount of new oil into the engine (consult the owner's manual for specifications).

3. Replace Oil Pressure Sender Unit (if faulty)

Sub-steps:
1. Locate the Sender Unit: Find the oil pressure sender unit, typically located near the oil filter or on the engine block.
2. Disconnect Electrical Connector: Carefully disconnect the electrical connector from the sender.
3. Remove Sender Unit: Use a wrench to unscrew and remove the faulty oil pressure sender unit.
4. Install New Sender Unit: Thread in the new oil pressure sender unit by hand and then tighten with a wrench.
5. Reconnect Electrical Connector: Reattach the electrical connector ensuring a secure connection.
