🔌 Denso 234-4744 O2 Sensor Review

The truck issued a code related to the location of the sensor on my truck. Fits exactly what my truck needs. A friend helped me with the installation as he has more experience with these installations. Erased the code on the truck with a code reader, then ran it and it works fine, no re-code.

You can't go wrong with OEM products. I fixed my check engine light and got my fuel trim back to normal. However, be aware that oxygen sensor problems are often misdiagnosed. So make sure this is the problem before replacing them. But the Revains price of $25 was half the cheapest place I could find in town. Great offer!

My '06 Dodge Dakota had codes P0420 and P0430 (Catalytic Converters Below Efficiency). Decided to replace the catalytic converters. It turned out that the old O2 sensors were worn out. After installing four new Denso O2 sensors, the codes disappeared. Cheap repairs for less than $100 (all four sensors) instead of replacing catalytic converters ($500-$1,000).

Fits perfectly on my 2005 Ram 4.3. I had a P0038 trouble code and thought I had a bad O2 sensor. Local parts dealers charged three times the price and, unlike Denso, are not OEMs. It took me about fifteen minutes to install, clean the code and the problem was solved! Make sure you have access to a dedicated O2 socket (I already have one) and save big by not paying a mechanic!
