2000 V6 Camry error code P1130

[Frank]

No engine check light, just one monitor (EV) so got the car smog tested and
pass with flying colors. Change the battery and driven the car 20 miles,
check engine came on the next morning but went off by itself after a 100
mile trip. Came home and scan for error codes. I still have the EV monitor
but a new P1130 error appeared, check engine light is off.

After checking Goggle, I see someone else had the same P1130 after
installing a new battery. Wonder if the battery change cause this and if the
P1130 would go away or should I fix it now?

Batteries should be charged before installation because some sat for a
while on the shelf and lost charge. Given ECM may or may not work well
you should clear the code and see if it comes back. This has nothing
to do with EV diagnostics test. If it repeats then it must likely is
the Denso sensor going bad (and not ECM, air leaks, etc).

For non-Calif you can use a Bosch planar sensor (upstream and
downstream) and avoid the Denso; for Calif emissions you're stuck with
Denso (the Bosch Calif wideband one is actually a Denso reboxed until
there's enough demand.)

Answer
These DTCs indicate a malfunction with the AF/R sensor Bank One/Sensor
One, (B1/S1)it is located near the firewall in the exhaust manifold, I
don't deal with part numbers,all I can tell you is which sensor is
malfunctioning according to the information you have given me. There
is a special tool needed to remove it,(O2 sensor socket). The battery
has nothing to do with this.There is no difference in the year model
either.

Thanks for the info, John.

I'm in California. Couple of local parts dealers I've called said they don't
have the A/F R sensor for B1/S1 (or B2/S1) but they have an O2 sensor for it
(Bosh 15733). Also Amazon.com has this Bosch O2 sensor as well for the 2000
V6 Camry. A/F R and O2 sensors have different electrical characteristics,
I'm really confused.

For California upstream sensors, you are basically stuck with Denso.
Either buy a Denso or a reboxed Bosch, which will be a Denso. And
Denso branded is cheaper ($137-145 on rockauto.com, #2349009 Right
bank, #2349007 Left bank)

The Bosch universal #15733 is for downstream Calif only. However, this
excellent planar type can be used upstream only in non-Calif
applications.

Thanks for the help again. I've reset it a few days ago and so far its clear
of any error codes and the EV monitor as well.
