CHECK ENGINE LIGHT, OBD2 MODE $06 CODE TI

1999 Toyota Camry

Engine problem
1999 Toyota Camry 6 cyl Front Wheel Drive Automatic 77335 miles

I just got a check engine light on my 1999 Toyota Camry V6 sedan. My OBD2 car-code scanner software reports FAIL on these two items:
Under the OBD2 Mode $06 category:
It reports:
TID " $07 Manuf Def", CID $01, Value -1 FAIL
and also
TID " $07 Manuf Def", CID $10, Value -1 FAIL

I believe it refers to Bank 1, Sensor 2 Oxygen Sensor from what I read on a web search.
But in researching what O2 Sensor(s) to buy, it is confusing the way the auto parts stores list these O2 sensors. Some say that two " Before Catalytic Conv" are required, Some say one. And then the kicker is that one site warns that some Toyota Camry's with a VIN " F" or " G" letter, use an " Air to Fuel Ration" sensor instead of an O2 sensor and they say do not confuse the two similar looking sensors? So how do I know what sensor my particular car has? My VIN number starts with a " JTZ.&Quot; or something. Is it by beginning letter of the VIN number? Also, if I have the O2 sensor model Camry V6, which sensor is Bank 1, sensor 2? And where is it located. I see two similar looking O2 sensors under my hood. One is right up front on the exhaust pipe, the other is behind the engine in a tight spot between the firewall and engine. I take itthose are the two " Before Catalytic converter" O2 sensors? I don't see the " After Catalytic converter" O2 sensor. Any help would be appreciated.

Dont get scared. Your car has 3 o2 sensors and your bank 1 sensor 2 is the oxygen sensor behind the cat converter.(The one farthest away from the engine) your car would have an air fuel sensor only if it has california emissions. You can check this by the engine tag under the hood. It will this vehicle is emission certified for california emissions for the year 1999. Or federal emissions for the year 1999. Hope this clarifies it. When you go to parts store just tell them you want the down stream o2 sensor, they will give you the right one. Votes and positive feedback on me is greatly appreciated if I have helped you.

Mastertechtim Thanks for your reply. I take it that you mean the " After the Catalytic converter" O2 sensor then is Bank 1, sensor 2? Why do they call it Bank 1, sensor 1 and sensor 2, and Bank 2 sensor 1 I wonder. It makes me thnk that Bank 1 is the front two O2 sensors and Bank 2 is the single rear (or After catalytic conv) sensor. Where would that rear O2 sensor be located? Do I have to access it from under the car as I cannot see it from the top hood compartment? I am still trying to figure out if those error FAIL codes I gave in my original question post is even related to the O2 sensors. If someone who is familiar with the Toyota OBD2 Mode $06 codes can tell me, then I can be sure and start tackling the replacement of the O2 sensor. If your answer turns out to help me solution this, I sure will give you a vote! Thank You!

It was very confusing for me at first, because it does not sound logical. How they number them is like this. Bank 1 is the bank of the engine with the #1 cylinder on it, bank 2 is the other cylinder head. Bank 1 sensor 1 is the o2 on the bank with cyl 1 closest to the engine. Bank 2 sensor 1 is the o2 sensor closest to the engine on the other cylinder head. Bank 1 sensor 2 is the next one behind bank 1 sensor 1 which is after the cat converter. It could also have bank 2 sensor 2 which is the o2 behind the cat on the bank on opposite side of bank 1.

Yes it is confusing indeed the way they labled them.
I read that the bank 1, sensor 1 is the one between the engine and the firewall, bank 1 sensor 2 is as you said the after catalytic converter sensor, and bank 2 sensor 1 is the one up in the front of the engine by the radiator. I am still trying to find out what those OBD2 TID CID codes mean. I found a document of another OBD2 scanner that mentions the codes in general

but I want to make sure it is all standard code numbering conventions use here for all manufacturers and that Toyota's code assignments are not different from this.

Mastertechtim, I checked under my hood today and lo and behold, it is a California Emissions Passed car that I have. So I guess all my sensors are of the Air/Fuel Ratio type and not O2 sensors. With that in mind, I asked my OBD2 CarCode maker about why I am not getting the response codes for TID $07, CID $01 and $TID $07, CID $10 tests using the 1999 Camry data file. He told me to use the Year 2000 Camry data file as that includes data points for TID $07. I did that and got a response back now that $TID $07, CID $01 PASS. But the other TID $07, CID $10 test is still not recognized and returns FAIL.
In addition I did receive a new return code of P1155 saying A/F Heater Malfunction (Bank 2, Sensor 1).

I looked this P1155 code up (for Toyota) on the internet and got conflicting info! Some sites say this code is for Bank 1, Sensor 2 and other sites say that this code is for Bank 2, Sensor 1. I don't know what to believe now. Anyone know for sure what Bank and what sensor code P1155 for Toyota's is for?
