Replacing O2 Oxygen Sensor on my RSX Type S: Troubleshooting and Fixing Check Engine Light

In this video, I'll take you along on my journey of diagnosing and fixing a Check Engine Light (CEL) issue on my RSX Type S. Within the first two weeks of owning the car, I encountered my first CEL, and it was time to investigate and resolve the problem. Using an OBD2 reader, I discovered that the CEL code was P0139, indicating low voltage from the secondary oxygen (O2) sensor. To confirm the diagnosis, I analyzed the live data and concluded that the O2 sensor needed replacement. Join me as I walk you through the process of changing the O2 sensor, located underneath the car at the catalytic converter. I'll share the necessary parts and tools required for the job and provide step-by-step instructions on disconnecting the plug, removing the old O2 sensor, and installing the new one. After completing the replacement, I verified the voltage readings using the OBD2 reader. Witness the moment when the CEL disappears, indicating a successful fix. However, I didn't stop there—I retested the voltage to ensure everything was functioning correctly. Follow the timestamps provided in the video to jump to specific sections if needed. I hope my experience and the troubleshooting process can assist you if you encounter a similar issue with your vehicle.
