Help with '97 engine codes

[k97camry]

Hello,

Recently my check engine light came on. I used a code reader, which gave me the codes: P0171 (System too lean, bank 1), P1135 (Air fuel sensor heater circuit response malfunction), and P1130 (air fuel sensor circuit range performance).

I was hoping someone could tell me, or confirm, that this is the oxygen sensor in the front of my camry (1997, LE 4 cylinder).

Also, since this check engine light has come on, my car has been running sluggish (choppy accelleration throught the RPM's, not very smooth).

I am really hoping that this is my front oxygen sensor, and that replacing this will fix the problem.

Thank you very much for your time.

you are correct, thoes codes mean a bad A/F (O2) sensor. the sluggish performance is a result of the car putting itself in limp mode.

Does anyone know the cheapest place to get a replacement part?

[bigbird]

ebay...but ull get what ya pay for. id go yota on this one.

Dealer, aftermarket ones I've heard bad stories on.

Can someone possibly link me to somewhere to buy an OEM O2 sensor?

Just to clarify, this is my oxygen sensor/air-fuel sensor (meaning they are the same thing?)

Thanks

I am trying to buy this part online, but some places are saying that the Oxygen sensor is different from the Air-Fuel Ratio Sensor.

Oxygen Sensor
OE Style
Before cat; req. 1
On exhaust manifold
Toyota Camry 97-01, some have an'Air-Fuel Ratio Sensor'(OE #89467-xxxxx). This is NOT an Air-Ratio Sensor. Does NOT
replace units with OEM numbers beginning 89467-xxxxx. If connector does not match do not install. From 08/2000 to
06/2001, an air fuel mixture ratio sensor is used NOT an O2 sensor.

I assume this is the sensor I see when I am looking directly at my engine, coming out of the exhaust manifold.

Also, I am in California...if that makes any difference.

So do I want an Oxygen Sensor, or an Air Fuel Ratio Sensor?

Thank you!

EDIT: Will this work? http://cgi.ebay.com/ebaymotors/Air-F...spagenameZWDVW

Even though it says for '05-'06 camry, the part number looks correct (89467)

An oxygen sensor and an air fuel ratio sensor are two names for the same thing. It does matter if your car has the california emissions package though. The part numbers I got were 8946506010 for the Federal emissions and 8946733011 for the Cali emissions. The easiest way to see which one you need is to call the dealer and give them your VIN and ask them for a price and part number. That way you can check their price against prices online. Good luck.

Don't buy aftermarket o2 Sensors.

[k97camry]

OK well I called the dealership and he told me that the part # is 89467 33011, and that from my VIN number, my camry is a California Emissions Vehicle. So that part number above is the one I want.

The dealer in town wants $228.27 for the air fuel ratio sensor (he told me its much different than an o2 sensor)

I found the OEM genuine toyota part on ebay:

I am going to go with the ebay item as I will save 50%. If anyone object please let me know.

Otherwise I believe 89467-33011 should solve my problem.

Thank you all.

OK, I replaced the sensor and the car seems to be running a lot smoother, but the check engine light is still on. I only drove about 4 miles, how long does it typically take until the check engine light turns off? Should I just clear it with my scan tool?

Thanks!

[ASG14]

Yup, just clear it, and it should stay off (and get better mpg). If you don;t have the scan tool, just unhook your (-) battery terminal for a minute and it will reset it as well.

Glad it runs better!

[k97camry]

Just to make sure. I ran my scan tool and it brought up the same codes...does that just mean that it hasn't recognized the new air/fuel sensor...or what?

So I should just clear all the codes, and hopefully they wont come back?

[Maim Menu]

Yes, erase them with your scanner and see if they come back. Hope it worked!
