03 Honda Accord 4cy o2 sensor

Got a code PO 135 and I replaced the primary O2 sensor and still have the same code any ideas would be appreciated

Actually, this generation of Hondas have two sensors. Which one did you replace? What brad did you choose? Hondas like OEM. Denso is a good brand.

Good luck,

Sam

Just reread your post. You say, you replaced primary one.

But another question still stands: what brand?

Aftermarket sensors do not work!

Good luck,

Replaced the primary o2 with a Bosch but going to replace that one with OE Honda sensor,Denso is cheaper but tired of replacing it,will post if OE fixes the problem,thank u for reply

Replaced both sensors with Honda parts took care of the "Light".Rear sensor requires removal of passenger seat for access to pigtail but that was no problem
