Hi..

Honda Accord. 2002 V4, SE 4 Dr.

Have Check engine light on. I checked the light code and it long blinked 4 times 1 short blink.

Books says..

P0135...41...Primary Heated O2 Sensor Circuit Mal function

I called Autozone.. He said he is not sure if it is a Pre cat or Post cat.

ULEV one is for 225.99 or some.. non ULEV is 100.99

Any help suggestions?

Should I take it to honda or I can just buy this O2 Sensor and Replace it my self.

I am pretty good with mechanics.. but not sure where this O2 Sensor it. I found one but that is the one I need to replace or there is some else I need to do?
