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 avoid electrical shorts.

2. Change Engine Oil and Filter

Sub-step 2.1: Drain the old oil
- Place an oil drain pan under the oil pan.
- Remove the oil drain plug using a socket wrench; allow the oil to fully drain.
Sub-step 2.2: Replace the oil filter
- Locate the oil filter and use an oil filter wrench to remove it.
- Apply a thin layer of new oil to the rubber gasket of the new oil filter before installation.
- Install the new oil filter, tightening it according to the manufacturer’s specifications.
Sub-step 2.3: Refill with new oil
- Replace the oil drain plug and tighten it to the specified torque.
- Use a funnel to pour the correct type and amount of new engine oil into the engine.

3. Replace Oil Pressure Sending Unit (if faulty)

Sub-step 3.1: Locate the oil pressure sending unit
- Consult the vehicle’s service manual for the exact location.
Sub-step 3.2: Disconnect the wiring harness from the sending unit.
Sub-step 3.3: Remove the sending unit using a socket or wrench.
Sub-step 3.4: Install the new sending unit and reconnect the wiring harness.

4. Verify Oil Pump Functionality (if necessary)

Sub-step 4.1: Attach a mechanical oil pressure gauge to the engine's oil pressure port.
Sub-step 4.2: Start the engine and monitor the oil pressure reading.
Sub-step 4.3: If oil pressure is still low, consider replacing the oil pump.
