Lillyan,

welcome...!!
I'm a newbie as well, to this list......
Been a mechanic a while ago, spent
many years in the field- but got out
of it professionally around the mid-late
90's.

Your code is- P1135Air/Fuel Sensor Heater Circuit Response. (Bank 1 Sensor 1)

Could just be the A/F ratio sensor, but I would leave that to
the much more experienced on this list?!! :)

Do you know if your vehicle is of the California Emissions standard?

Sincerely, Bob Z. :)

Help
 

Please help! I have a 2000 Camry Solara 4 cylinder and I recently had my car diagnosed by PepBoys after failing Connecticut Emissions Testing with several codes. One of those codes was a P1135 and the mechanic at PepBoys stated that the oxygen sensor needed to be replaced. I had every thing that they stated needed to be repair fixed including non-related emissions repairs. However, my check engine light has come back on with a P1135 error.

Am I missing something?:mad:

Hi,

do you happen to know if the sensor was an *air/fuel ratio* sensor;
and not just a generic O2 sensor... it does matter from what I've been
told and read...... :)

Just my humble opinion. :) :)

Sincerely, Bob Z.

Which sensor did you replace?

As Debunker states, make sure the sensor is the right type (A/F or 02). Denso and Toyota brands seem to work best.

Thanks for responding. I replaced the sensor behind the catalytic converter. These repairs are starting to be very costly.

P1135 is a code for the first sensor found on the exhaust system when starting from the cylinder head and moving back to the mufflers. Location is called Bank 1, Sensor 1.

Go to the link below:

2001 Toyota Camry Problem Check Engine Light On, Code P1135

There are 3 photos below the photo of the book with the words Chilton on it. The first 2 show the typical location of this first sensor. You should be able to see this sensor when looking inside the engine compartment.

The 3rd photo shows a typical sensor location behind the converter. This sensor has a different code.

Make sure the correct sensor was replaced and that it was an A/F sensor design (not 02).

Hello again folks,

just an update for me... I just replaced my A/F ratio sensor
(finally) on my 1998 Camry 2.2l. (as Toyomoho had suggested).

Cleared the code that kept popping up randomly-
P0171 System too Lean(Bank 1)(Sensor 1)

All seems to be fine now- no more light...... THANX
Toyomoho!!!!!!

Will report on mileage soon............!!

'98 Camry - oxygen sensor - CA or not?
 

1998 Camry LE, 2.2L

My daughter called me to report that her CEL is on and she's getting a P1133 and P1135 codes. So, I figure I need to replace the upstream oxygen sensor. Then I remember that the part is different for CA-compliant cars, so I ask her to check the sticker under the hood. Here's what she sent back:

"...meets the standards set by the US EPA and the state of california"

Does this mean I need a CA-compliant sensor? As I understand it, the parts are very different (in function and in price), so I have to get this right.

Is there anything else I should look for to be absolutely sure I have the correct part? Is she looking in the right place?

Thanks!

'98 Camry - oxygen sensor - CA or not?
 

Hello everyone....

just my 2 cts' worth again........ :)

My 98 Camry has the California Emissions,
and I did get the "California Emission" air/
fuel sensor when replacing mine (upstream).
No issues since replacing it, as Toyomoho
suggested to me.

As I was going to post awhile ago also, the
mileage has been pretty decent. High 20's
for mostly highway, low 20's in the city. I'm
happy. Always looking for little tricks to up
those figures a bit!! ;)

But back to you/your A/F sensor, there is
the California Emissions, and Federal Emissions
packages- that about it as far as I know.......

I say get yourself the Denso (NON-Universal)
upstream A/F sensor from whoever has it the
cheapest you can find! (listed as a direct-fit
for me in my area/part stores)

Sincerely, Bob. :)

State of California = California Emissions.

Thus follow Debunker's info and get a California part, Denso (not universal type) or Toyota OEM part.

Unless the check light is blinking there repairs are not urgent.
