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

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the battery to prevent electrical shock.
• Allow the engine to cool down before working on the oxygen sensor.

2. Replace Oxygen Sensor

1. Locate the Sensor:

   • Identify the upstream oxygen sensor (Bank 1) located before the catalytic converter on the exhaust manifold.

2. Remove the Old Sensor:

   • Using a socket wrench and an oxygen sensor socket, carefully unscrew the old oxygen sensor from the exhaust pipe.
   • If it's stuck, apply penetrating oil and wait a few minutes before trying again.

3. Install the New Sensor:

   • Apply anti-seize compound to the threads of the new oxygen sensor.
   • Screw the new sensor into place by hand initially, then tighten with the socket wrench to the manufacturer’s specified torque (typically around 30 lb-ft).

4. Reconnect the Wiring:

   • Plug the electrical connector back into the new oxygen sensor ensuring a secure fit.

3. Clear Codes

• Reconnect the battery.
• Use the OBD-II scanner to clear the P0134 code from the vehicle’s computer.
