Review on 🏎️ Denso 234-9005 Oxygen Sensor: Unparalleled Performance and Precision by John Carter

03 The CR-V gave a code that kept going on and off after I replaced the starter motor so the intake manifold had to be removed. I didn't replace the gasket so I figured maybe it was leaking causing the O2 sensor to read incorrectly. Gasket replaced, bulb reinstalled and it started again. Studied the code and they suggested replacing the O2 sensor in front of the cat. When attempting to remove the sensor using a dedicated O2 sensor removal tool, it turned out to actually be surprisingly easy. Maybe it was free. I smeared the thread with non-stick compound and tightened it well. Without resetting the code, I started the car and the light went off immediately and wouldn't come on again. Denso is Honda OEM product without Honda stamp and not in Honda box. Other reviewers said the product was made in the garage. You must take these reviews for disbelief. Not every person with a Revain account is a mechanic or can even hold a wrench. The vehicle is now generating codes for the upstream oxygen sensor again. When traveling, the light is not intermittent. Let's see what happens when I get home.
