P0134 Honda CRV Error: Comprehensive Diagnosis and Troubleshooting Guide

Today, I’m going to show you how to replace an O2 sensor and solve some engine problems. I have a BlueDriver code reader, and I’ll walk you through the process of using it to diagnose and fix issues with your car.

First, I’ll connect the BlueDriver code reader and get the readout via Bluetooth to start getting readings.

Upon diagnosing, I found a 20 amp fuse in the fuse box that needed checking. It’s crucial to inspect this fuse as it powers the airflow sensor. If the fuse is faulty, it can impact the sensor’s functionality. In my case, the fuse was fine, so I proceeded to replace the airflow sensor and the O2 sensor on the car.

To begin the replacement process, I raised the car using a jack and placed jack stands for safety. It’s essential to secure the car properly before going under it. I bought the necessary tools, including the O2 sensor and the O2 sensor socket wrenches from AutoZone to complete the task.

The O2 sensor is an expensive part, costing around $160 plus tax. Additionally, I needed to use a specific wrench for the replacement, which I got as a loaner tool from AutoZone.

After getting the tools and parts ready, I proceeded with the replacement. It involved removing the old O2 sensor, applying dielectric grease, and installing the new sensor securely. I also demonstrated how to handle the sensor connectors and the wiring during the replacement process. Once the replacement was done, I cleared the error codes and tested the car to check if the issue was resolved.

Fortunately, the check engine light did not come back on after the replacement, indicating that the O2 sensor replacement had fixed the problem. This part, though expensive, was essential for solving the engine issue, and I was pleased with the result.

Finally, I highlighted the benefits of using the BlueDriver diagnostic tool for the car’s maintenance, which provides valuable feedback and assistance from mechanics through email, helping to save money on repairs and replacements.

With the successful replacement and resolution of the engine problem, I concluded the task, satisfied with the outcome.

How do I connect the blue driver code reader?

You need to connect the blue driver code reader via Bluetooth. Once connected, the blue light will turn on and you can start getting readings.

What should I check if I have a problem with the airflow sensor or temperature?

If you have a problem with the airflow sensor or temperature, check the 20 amp fuse for the LAF heater. It’s the first yellow fuse on the left in the fuse box inside the car.

How do I change the airflow sensor or O2 sensor?

To change the airflow sensor or O2 sensor, you’ll need to jack the car up, locate the sensor, use the appropriate tools like an O2 sensor socket wrench, and apply dielectric grease before tightening the new sensor in place.

Can I get help with diagnostic tools like the blue driver code reader?

The blue driver diagnostic tool provides a lot of information and feedback. Additionally, you can get help from actual mechanics who can send you information via email, though it may take a day or two for a response.

Did the O2 sensor fix the issue with the check engine light?

It looks like the O2 sensor may have fixed the problem, as the check engine light no longer comes on. It seems to have been a $200 fix, which may have been a little pricey, but necessary.
