Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and allow the engine to cool.
Disconnect the battery to ensure safety while working on the electrical system.

2. Check and Top-Up Engine Oil

Tools Required: Oil filter wrench, funnel, rags
Remove the oil filler cap.
If the oil level is low, add the correct type of engine oil (consult the owner's manual for specifications).
Replace the oil filler cap securely.

3. Replace Oil Pressure Sending Unit (if faulty)

Tools Required: Socket set, wrench
Locate the oil pressure sending unit on the engine block.
Disconnect the electrical connector from the sending unit.
Remove the sending unit using the socket set.
Install the new sending unit by screwing it into place and tightening to manufacturer specifications (usually 10-15 Nm).
Reconnect the electrical connector.

4. Replace Engine Oil and Filter (if degraded)

Tools Required: Oil filter wrench, socket set, drain pan, funnel
Place a drain pan under the oil pan and remove the drain plug to drain old oil.
Once drained, replace the drain plug and tighten it.
Use the oil filter wrench to remove the old oil filter and install a new one.
Add new engine oil according to specifications through the oil filler cap.
