Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off and cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace Engine Oil

Remove the oil filler cap and check the oil level.
If low, add the manufacturer-recommended oil type (5W-20 for the 2023 Honda Pilot).
If oil is dirty or contaminated, drain the old oil by removing the drain plug and allow it to fully drain into a pan.
Replace the drain plug and tighten it to the manufacturer's torque specification (typically around 20 lb-ft).
Refill the engine with new oil through the filler neck.

3. Inspect and Replace Oil Filter

Use an oil filter wrench to remove the old oil filter.
Apply a small amount of new oil on the rubber gasket of the new filter.
Install the new oil filter, tightening it to the manufacturer's specifications (usually hand-tight plus a quarter turn).
Ensure no oil leaks are present after installation.

4. Test Oil Pressure

Remove the oil pressure switch using a socket wrench.
Install a mechanical oil pressure gauge in place of the switch.
Start the engine and observe the oil pressure readings; it should be within the manufacturer's specified range (typically 20-60 psi at idle).
If pressure is low, further inspect the oil pump or consider replacing it.

5. Reassemble and Test

Reinstall the oil pressure switch if the pressure is normal, or address any issues found.
Reconnect the negative battery terminal.
Start the engine and check for the low oil pressure warning light.
