Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the vehicle battery to prevent electrical shock.
• Allow the engine to cool before proceeding.

2. Remove the Oxygen Sensor

• Locate the upstream oxygen sensor (typically near the engine on the exhaust manifold).
• Use an oxygen sensor socket or wrench to carefully unscrew and remove the old oxygen sensor from the exhaust system.
• Be cautious to avoid damaging surrounding components.

3. Inspect and Clean

• Inspect the oxygen sensor port for carbon buildup or debris.
• Clean the area using a wire brush or vacuum if necessary.
• Ensure that there are no exhaust leaks in the vicinity of the sensor port.

4. Install New Oxygen Sensor

• Apply anti-seize compound to the threads of the new oxygen sensor (if required).
• Screw in the new sensor by hand to avoid cross-threading, then tighten it to the manufacturer's specifications (typically around 30 Nm).
• Reconnect the electrical connector securely.

5. Reconnect Battery and Clear Codes

• Reconnect the vehicle’s battery.
• Use the OBD-II scanner to clear the P0133 code from the system.
