denso : Denso 234-9028 Oxygen Sensor (Air and Fuel Ratio Sensor) Reviews
This review is from: Denso 234-9028 Oxygen Sensor (Air and Fuel Ratio Sensor) (Automotive)
I'm happy that my check engine light is gone. I'm hoping my gas mileage will improve too. I also bought an oxygen sensor socket which didn't work for me. If you have a sensor that's really stuck..you need to cut the sensor's wires and use a regular deep socket to avoid stripping the o2 sensor. The engine must not be too hot..spray some PB blaster on the sensor. The sensor came off but it took the threads with it..no biggie, I'm prepared for that. I used a thread chaser to fix and clean the threads. Installed the new sensor and everything is good :)

The oxygen sensor fit perfectly and was very easy to install. I reset the check engine light and it did not come back on so this oxygen sensor was the correct one and it works great.I also felt that I got a very good price on this item.

A Toyota dealer would charge you between $200-$300 to change this sensor, and the other 3 like it before the catalytic. But if you get a steady check engine, truck on down to Auto Zone where they will be more than happy to read you out the error code. The error code format is: Bank 1 Sensor 1, Bank 2 Sensor 1, etc. Bank 1 is driver's side of the exhaust. Bank 2 is passenser side of the exhaust. Sensor 1 - first sensor that side counting from where the exhaust manifold attaches to engine. Now you hop on the internet and correlate the error code with the Denso or Toyota part number. Then you order the part, in this case, $120+. There is a $100 variation in part prices, but this is 2010, you know what to do.
