Review on Denso 234-4706 Oxygen Sensor: ๐ Reliable Performance for Optimal Fuel Efficiency by Darren Anderson
Solved Faulty "Check Engine " Light - O2 Sensor Code
Dealer wanted to replace my upstream and downstream oxygen sensor and cat exhaust system for $1500 to get the "CHECK ENGINE" - Fix light problem. I decided to change the oxygen sensors myself. Fix that and I get 28mpg versus 23mpg before new sensors. Highly recommended!
