Solution

1. Preparation

Gather required tools and parts.
Disconnect the battery before working on electrical systems.
Ensure the engine is cool to avoid burns.

2. Verify Oil Change Installation

Inspect Oil Filter:
- Remove the engine cover if necessary.
- Check the oil filter for proper installation and signs of leaks.
- If the filter is misaligned or leaking, replace it.
Check Oil Level:
- Remove the dipstick and clean it with a lint-free cloth.
- Reinsert the dipstick, remove it again, and check the oil level.
- If the oil level is above the full mark, drain excess oil until it is at the correct level.

3. Inspect and Replace O2 Sensor (if applicable)

Locate the O2 Sensors:
- Identify the upstream and downstream O2 sensors based on the error codes.
Remove and Replace:
- Disconnect the electrical connector from the sensor.
- Use an O2 sensor socket to remove the sensor from the exhaust manifold or pipe.
- Install the new sensor and reconnect the electrical connector.

4. Clear Error Codes

Reconnect the battery.
Use the OBD-II scanner to clear any stored error codes.
Start the engine and monitor the check engine light.
