Post subject: Correct P/N for 1999 Avalon Calif Bank 1/ Sensor 1 (Rear Bank A/F
Archived from groups: alt>autos>toyota (more info?)

I am trying to find the correct A/F Sensor Bank 1/ Sensor 1 (Rear Bank
at Firewall, Upstream Sensor) for a 1999 Toyota Avalon V6 / 3.0L
(1MZFE) Calif . Not all of the Toyota dealers give the same part
numbers for B1S1. Some dealers give the P/N234-9009 (OE
#8946741011) ; Front; Left; Calif. and some the P/N is 234-9007 (OE #
8946741021) , FRONT; LEFT Calif. Denso tech line gives 234-9007 (OE
# 8946741021). Who is correct? Is there any difference between the
sensors other than the harness wire length?

Bank 1 Sensor 1 is on the bank that contains the #1 cylinder.

According to NapaOnline.com, both Bank 1 and Bank 2 Sensor 1 are the same.
The cost is $192.00.

California emissions vehicles use Air-fuel sensors, while other vehicles use
O2 sensors.

The operation of B1S1 and B2S1 are exactly the same so there is no
difference in the operation of B1 and B2 sensors.

And, _IF_ there was a difference, it would be in the length of the wires,
and the makers of replacement parts would try to make one part to fit both
applications, so they would give us the part with the longer leads.

I like to think that Toyota engineers would try to make one part fit no only
this car, but every car that used this engine, but I live in a fantasy land.

When I read the parts description on napaonline.com, only the After CAT
sensors had California and Except California variants. the Before CAT
sensors were the same without regard to Calif.

Some aftermarket emissions parts, particularly catalytic converters, cannot
be sold for OBD II vehicles in California, probably because they don't meet
CA's emissions standards. What many people do not realize is that 50 state
and CA emissions vehicles are physically the same, with the difference being
quality sampling.

Frankly, I'm a little confused by this entire line of discussion. I thought
there were no more, "California," cars. I thought that the days of cars
being built for 49-states and California were long gone. I was surprised to
find that there is a listing for a smog part that is specifically for Calif.

As far as I know, there are still California emissions requirements for
motor vehicles, and some East Coast states have adopted CA emissions
requirements, like MA, NY, VT. One of the differences is that CA emissions
vehicles use an Air/fuel sensor and federal vehicles use O2 sensors. I
don't know what the difference is, but that is one of them. Another
difference in CA emissions is that there are more frequent quality checks of
components on the assembly line, and CA emissions vehicles have longer
emissions warranty on some emissions components.
