Learn how to diagnose and fix P0133 oxygen sensor slow response in Honda Accord 2008-2012. Step-by-step guide with diagnostic procedures and repair instructions.

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery terminal to prevent electrical shorts.
• Allow the engine to cool.

2. Remove the Oxygen Sensor

• Locate the upstream oxygen sensor (usually before the catalytic converter).
• Use an oxygen sensor socket or a wrench to remove the sensor by turning it counterclockwise.
• Carefully disconnect the electrical connector from the sensor.

3. Inspect and Clean

• Check the threads of the oxygen sensor and the sensor port for carbon build-up or damage.
• Clean the port with a wire brush if necessary.
• Inspect the connector for corrosion and clean it with electrical contact cleaner.

4. Install the New Oxygen Sensor

• Apply anti-seize compound to the threads of the new oxygen sensor (if applicable).
• Install the new oxygen sensor by threading it into the exhaust manifold or pipe and tightening it securely using the oxygen sensor socket (torque specification: 30-40 lb-ft).
• Reconnect the electrical connector to the sensor.

5. Reconnect Battery and Test

• Reconnect the negative battery terminal.
• Start the engine and allow it to reach operating temperature, monitoring for any error codes.
