04 Civic EX CEL P0135 and P0134

[ndccpf1]

EX Automatic (1.7 VTEC) had CEL of P0134 Bank1 Sensor 1. I tested the
whte and green plug lead (heater) and was extremely his resistance. I
changed for a $ 70 OEM Denso.

Now I get P0135 O2 Circuit not Active Bank 1. Could it be the wrong O2
sensor or a bad one out of the box ?

IMHO, the O2 sensor codes are some of the most common AND deceptive/
money-wasting on record for the impulsive and/or intermediate/
uninitiated mechanic. They aren't necessarily wrong, but they both
(upstream & downstream) can have several causes. I have a basic scan
tool (limited in it's diagnostic details of course) and can't count
the number of folks that I've loaned it to (or scanned myself) where
it said it was this or that O2 sensor or bank 1 or bank 2...and they
replaced it, and BOOM! The same code returns. Just saying: If it
says it's an O2 sensor, it definitely may be, but several other
factors go into what the O2 sensors read, and how 'other' probs can
throw these codes and cause a false negative on the O2 sensors.

From here I defer to my personal deities on this board for a proper
face-slap or portion of gruel: Tigger, Beamer, Nasty, and Grumps.

Another poster / forum reply was apparently the store sold me the
Narrow Band (for VTEC-E) and I need the Wide Band for VTEC. I will be
calling them today. Narrow band is $ 70 and Wide Band is $ 270.00
(Honda wants $ 370.00).
Have used my scanning tool for a few other O2 sensor replacemts in the
past and all worked well. Now the finer details show themselves on the
secifics of the engine (VTEC-E and VTEC are same liter and
displacement).

Many thanks !

i would go to denso's website, look up their part number, then dags for
online retailers listing that number. amazon for instance. you can
also try ntk sensors which sometimes are a little cheaper than denso,
but work fine on honda, unlike some of the other aftermarket stuff out
there like bosch.

Your car needs an A/F sensor, not an oxygen sensor. A/F sensors operate on
a different principle from ordinary oxygen sensors.

An oxygen sensor signal flip-flops between .1 and .9 VDC, while an A/F
sensor signal is a gradually varying voltage. The ECM can only read the
signal it's meant to read.

more commonly known as an afr [air fuel ratio] sensor, otherwise known
as a wide band sensor. it most definitely /is/ an oxygen sensor.

yup. see above.

Technically true, but the trade refers to the two by different names.

If you need an "air/fuel" ("A/F") sensor, you need to ask for that, not an
"oxygen sensor", regardless of whether you preface the phrase "oxygen
sensor" with "narrowband" or "wideband".

i'd rather we stuck with the technically true than the colloquially
misinterpretable.

Back from travelling and removed the $ 70.00 O2 sensor (NAPA sold me
the one for VTEC-E engine). New one was $ 298.00 Installed and cleared
codes.
Car is good as new !
