Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery cable for safety.

2. Check and Add Oil

Remove the dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the oil level.
If low, add the appropriate grade of engine oil (consult owner's manual for specifications).

3. Replace Oil Pressure Sending Unit

Locate the oil pressure sending unit (generally near the oil filter).
Disconnect the electrical connector and remove the sending unit using a socket.
Install the new sending unit and reconnect the electrical connector.

4. Replace Oil Filter

Place an oil catch pan under the oil filter.
Remove the old oil filter using an oil filter wrench.
Apply a small amount of new oil to the rubber gasket of the new filter.
Install the new oil filter, ensuring it is snug but not over-tightened.

5. Replace Oil Pump (if necessary)

Drain the engine oil completely.
Remove the oil pan (may require removing other components for access).
Remove the oil pump from its mounting.
Install the new oil pump, ensuring proper alignment.
Reinstall the oil pan with a new gasket, torquing to manufacturer specifications.

6. Refill Engine Oil

Refill the engine with the recommended oil type and amount.
Reconnect the negative battery cable.
