Solution

1. Preparation

Gather all tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid any electrical issues while working.

2. Check and Adjust Oil Level

Remove the dipstick, wipe it clean, and reinsert to check oil level.
If low, add the recommended oil type (typically 0W-20 for Honda Civics) until the level reaches the "Full" mark on the dipstick.

3. Inspect Oil Filter

Using an oil filter wrench, remove the oil filter and inspect the rubber O-ring for proper placement.
Ensure that the new oil filter is installed correctly and there are no leaks.
If the old filter was not replaced, install a new one that meets OEM specifications.

4. Inspect Oil Pressure Sensor

Locate the oil pressure sensor, typically near the oil filter or engine block.
Disconnect the electrical connector and remove the sensor using a socket wrench.
Inspect the sensor for any signs of damage or wear.
If damaged, replace it with a new sensor and reconnect the wiring.

5. Reset Warning Lights

Reconnect the battery and start the engine.
Use an OBD-II scanner to clear any stored trouble codes.
Monitor the dashboard for warning lights to see if they have turned off.
