how to fix the P0134 oxygen sensor code in my Honda CR-V Fifth Generation (2017-2022)

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery terminal to avoid any electrical shorts.
• Allow the engine to cool before starting work.

2. Remove the Upstream Oxygen Sensor

• Locate the upstream oxygen sensor, typically found on the exhaust manifold.
• Use a wrench or oxygen sensor socket to carefully unscrew the sensor from the exhaust.
• Disconnect the electrical connector by pressing the tab and pulling it apart.

3. Inspect and Clean

• Inspect the sensor threads for any carbon buildup or damage; clean if necessary using a wire brush.
• Check the electrical connector for any signs of corrosion or damage; clean the contacts with electrical cleaner.

4. Install New Oxygen Sensor

• Apply anti-seize compound to the threads of the new oxygen sensor (if not pre-applied).
• Screw the new oxygen sensor into position and tighten it to the manufacturer’s specifications (usually about 30 ft-lbs).
• Reconnect the electrical connector until it clicks into place.

5. Reset the Engine Control Module (ECM)

• Reconnect the negative battery terminal.
• Use the OBD-II scanner to clear the P0134 code and reset the ECU.
