Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, jack and jack stands, exhaust leak detector, multimeter.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the battery to prevent electrical issues while working on the exhaust system.

2. Repair Exhaust Leaks

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Locate the source of the leak using the soapy water method or exhaust leak detector.
3. If the leak is at a joint, tighten the bolts or replace the gasket as needed.
4. For cracks in pipes, either weld the area or replace the damaged section of the exhaust pipe.

3. Replace Oxygen Sensors

Sub-steps:
1. Locate the oxygen sensors (typically found before and after the catalytic converter).
2. Disconnect the electrical connector and use a socket to remove the old sensor.
3. Install the new oxygen sensor and reconnect the electrical connector.
4. Repeat for all faulty sensors identified during diagnostics.

4. Replace Catalytic Converter (if necessary)

Sub-steps:
1. Remove the exhaust pipe connected to the catalytic converter by loosening the bolts.
2. Unbolt the catalytic converter from its mounts and remove it from the vehicle.
3. Install the new catalytic converter and secure it with bolts, ensuring proper alignment.
4. Reattach the exhaust pipe and tighten all connections.
