98 Camry V6 XLE - Oxygen Sensor Problem (Code:P0135)
I had my check engine light on. When I got it checked @ autozone it popped up an error code P0135 saying " malfunction exists in the heater circuit for oxygen sensor 1 in bank 1"
Explanation: The computer has recognized a failure in this circuit. Probable causes are:
1.Oxygen sensor defective
2.Poor connection at oxygen sensor
3.Check circuit-fuse.
I believe that the oxygen sensor is defective and I need to replace it. I have been driving with this condition for almost 10 months. Will this affect my engine badly.
Please guide as to what sensor to use and how to replace. When I see the parts in autozone online I get 2 brands Bosch and Denso. Sometimes it says "2 required one at each exhaust manifold" and sometimes it says nothing as in the case of Denso.
How many sensors I need to replace actually? And please guide me as to how to replace it. I mean I wont do it myself. I will take it to a mechanic but I need to tell him where to look for. I've read the posts in the forum. They give directions. But how exactly? Has any got any pictures? And please, how many sensors I need to buy? 1 or 2?
Well, here is my advice,
I had the S1B1 sensor malfuntion earlier this year on my car so I can give you advice There are 3 sensors, one is right in front of you as soon as you open the hook, the other is the sensor you are referring to, S1B1, it between the engine and the firewall, the third one is under the car after the catalic converter. My advice, get Denso, none of the Bosch stuff. My thinking is, if it came with the car and it's lasted that long , then I should replace it with the same thing... Bosch tends to be found on European cars rather than japanese cars. You should be able to change the obvious one very easily, the other 2 require raising the car and changing from the bottom. Autozone will loan you the tool for free, so I'd say go for it, just give yourself some time. Don't think this is a 10 minute job. This ain't no oil change. My recommendation is to change all three on the basis that if one started malfunctioning, the others must be nearing that point as well...

But my question is when I try to order the oxygen sensor from autozone (S1B1) it says "Denso oxygen sensor federal standards before catalytic converter - need 2 one at each exhaust manifold". What does that mean? Do I need to buy 2 oxygen sensors or 1? which is "Sensor 1 Bank 1" ? The one between the engine and the firewall? If so, how many sensors that need? one or two?
I think ProjectVertex may be incorrectly telling his experience with the 4-cylinder version.
In your V6 1MZFE, the Bank 1 Sensor 1 is the "Right Bank" sensor near the firewall, before the catalytic converter (called "Upstream"). Even though you need 1, the other two may not be far behind.
Denso is the only choice thus far for "upstream" sensors, although Bosch, as a redistributor in addition to the First-Tier manufacturer, reboxes the Denso sensor because of the low Toyota V6 production volume. Just get the Denso, it's cheaper in many such cases.
The "downstream" sensor is just a traditional heated sensor. I'd recommend Bosch #13353 Planar type that's more resistant to contamination if the time comes. The rule is to get a planar whenever available.

Look on the underside of the Hood for the Emissions decal. It will tell you if you have a CALIFORNIA standard or Non-California standard. New York and Massettusetts also use Calif standard.
You have to select accordingly, basically Calif or Non-Calif.
I'd replace one at a time unless your emissions test is getting to the upper limit. Saves $$$.

Thanks JohnGD. At least that seems to suggest that my car is indeed Calif spec'd (i don't know how Hill/Ninja Wrench knew!). I'm in NY and the sticker seems to hint that it's a Calif car.
For anyone who has missed my 2001 Camry saga of "Is it California spec'd or not?": The hood sticker and Denso/Toyota Air/Fuel sensor suggets it's Cali. The VIN # (same on dash and hood) say it's not a Calif car.
