Review on 🔌 Denso 234-4603 Downstream Oxygen Sensor - 4-Connector 33.1” Wire Harness for Enhanced SEO by Douglas Davis

Bought this O2 sensor for my 2004 Toyota Camry LE 4 cylinder which had the check engine light on and the fault code was PO136 bank 1 sensor 2. This is the O2 sensor that is after the catalytic converter (not the sensor that is on the exhaust manifold pipe that is accessible through the engine bay). To remove the faulty sensor, I had to place my Camry on ramps so I could comfortably crawl under the car to use the 24 inch wrench extension to unscrew the old sensor. I couldn't move the old sensor with just a wrench and penetrating oil. This O2 sensor has electrical wires and a rubber grommet that allow the connector to be routed through the vehicle floor to make an electrical connection inside the vehicle (often under one of the front seats). My Camry has an electrical connector on the underside. I rolled up the extra cable and secured it to the underside of my car with zip ties. This sensor also comes with a small container of glue that you can apply to the sensor's threads for easier removal later. Do not apply the sensor probe sticky After about 15 miles of driving, the check engine light went out.
