Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Address Error Codes

Using the OBD-II scanner, note down the error codes.
Research the error codes to determine the likely components involved.
Clear the error codes using the scanner.

3. Inspect and Replace Components

If a faulty sensor is indicated (e.g., oxygen sensor, MAF sensor):
- Tools Required: Socket set, torque wrench, screwdriver set.
- Remove the faulty sensor by disconnecting the electrical connector and unscrewing it from the intake/exhaust manifold.
- Install the new sensor, ensuring to torque to the manufacturer’s specifications.
If a vacuum leak is suspected:
- Inspect all hoses and connections for cracks or disconnections.
- Replace any damaged hoses or reconnect any loose fittings.
