I get PO135 error code after service engine light came on.


Firestone says one of O2 sensors bad. Replace both.

car is 98 dx Civic with 57,000 miles.

Is that covered by emmissions dealer guarantee ?

That's P-ZERO, not P-oh. (P0135).

It's the sensor between the manifold and the cat (primary sensor). The
heater vircuit is bad.

You do *NOT* NEED TO REPLACE BOTH. Don't go to Firestone.

However...Correct procedure here is to clear the code and see if it
comes back. You might get lucky and it will stay away. If it comes back,
then replace the sensor.

Not likely. Oxygen sensors are only covered under a three year or five
year warranty. Call your dealer to be sure.

P0135 error code

Thank you for reply.

Car just passed california smog 2 months ago.

I tried resetting the error code with all the things you said on
TeGGeR. Won't go out.

Other ways to reset ?

Car running fine. I will check gas milage.

Called Honda america. They say not covered period.

How'd you try to reset it? By disconnecting the battery?

When the light came back on again, was it the same code? There are
literally 100 possible codes, so don't just assume it's the same one.

If the battery-unplug didn't work, and the light keeps coming back on
with the same code, then the heater is truly bad and the sensor must be
replaced.

The only other way to reset is with the OBD-II scan tool.

Won't tell you a thing. Will have no noticeable effect on mileage.

It was covered as part of the new-car warranty, which is obviously long
expired.

carry a fire extinguisher because at exhaust temps, epoxy burns.
unfortunately, cracked manifolds can't be economically repaired, so you
need to get a replacement from a junk yard [if you can - i believe
catalyst containing manifolds like your would be illegal to re-sell in
california] or buy new.

The JB epoxy disintegrated to powder easily scraped off with
screwdriver. Replaced it with manifold patch cement from autozone.

Replaced O2 sensor.

Sevice light off.

Thanks for the help.
