Frequently Asked Questions

Find answers to common questions about our products and services
  • This is the Rear (Downstream) oxygen sensor. It is installed after the catalytic converter and is strictly responsible for monitoring catalytic efficiency. If you need the sensor that controls your engine's air/fuel ratio, you are looking for the Front (Upstream) sensor.

  • Part number 4H0906265B is specifically mapped for Cylinders 1-4 (Bank 1), which corresponds to the Right / Passenger side on standard US left-hand-drive vehicles.

  • It depends. A P0420 code simply means the ECU is seeing incorrect data from this downstream sensor. If the sensor itself is lazy, fouled, or burnt out, replacing it will permanently clear the code. However, if your actual catalytic converter has melted or structurally failed, a new sensor will correctly report that the cat is dead, and the code will return.

  • Highly Recommended. Oxygen sensors are subjected to the exact same exhaust temperatures and heat cycles. If your Bank 1 downstream sensor has failed, your Bank 2 downstream sensor (part number 4H0906265C) is almost certainly nearing the end of its lifespan. Replacing them as a pair prevents you from having to crawl back under the car a few months later.

  • Yes, we ship to most countries worldwide.
