Review on Efficiently Monitor Air Fuel Ratio with Denso 234-5010 Sensor by David Shah

Was the correct part for my 2003 Honda Accord. I bought a part for installation at the Autozone for $10. It's as simple as disconnecting without damaging it, unscrewing the sensor, screwing in a new one, connecting the clamp without damaging it. For me, an amateur took maybe 10 minutes. Because I walked slowly to make sure I didn't damage anything. In 2003 there are 3. #1 is in the back and faces the engine, #2 is in front and faces the engine and #3 is under the passenger seat for the exhaust.
