Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid electrical shocks.

2. Address Error Codes

Based on the error codes retrieved from the OBD-II scanner, identify the problematic component(s).
If codes indicate a specific sensor (e.g., O2 sensor, MAF sensor), proceed to replace or repair that sensor.

3. Replace or Repair Components

For O2 Sensor Replacement:
1. Locate the O2 sensor (usually near the exhaust manifold).
2. Remove the wiring harness and unscrew the sensor using an appropriate socket.
3. Install the new O2 sensor and reconnect the wiring harness.
For MAF Sensor Cleaning/Replacement:
1. Disconnect the MAF sensor harness.
2. Remove the sensor from the air intake duct.
3. Clean the sensor with MAF cleaner or replace it if necessary.

4. Reassemble and Reconnect

Reconnect any removed components (e.g., air intake duct).
Reconnect the battery once all repairs are completed.

5. Clear Error Codes

Use the OBD-II scanner to clear the existing error codes.
Start the engine and observe if the check engine light remains off.
