Super expensive to order from Honda locally. Order from US, ~160USD.
Honda's factory primary O2 sensor is made by Denso (and one other company, forgot the name).
Closed loop operation requires primary O2 sensor for feedback. If you daily drive your DC5 R, it is best to replace the sensor, else fuel consumption and part-throttle performance will be crap...
P.S. Is engine check light on? What fault code? P0134 or P0135? 作者: CHIVAS 时间: 2011-7-28 18:16:18
I forgot the fault code. I dont know if the aftermarket sensor will work or not.cos my mate tried 2 of them on civic, none of them working
