O2 Sensors

[jackyboyf]

Is it easy to replace the O2 sensors on my 2002 Camry LE?

[Nervous]

Depends.

[rwd_3tc]

which sensors do you want to replace?

[Hajoca]

You need to check if you have Air Fuel sensors or Oxygen sensors.
Then 2 sensors on 4cyl or 3 sensors for V6 in total.
Sensor after the catalytic converter under the car is an O2 sensor.

that year is probably a/f ratio sensor pre cat and o2 post

I'm told the oxygen sensors. I think they're 2

Which motor? 4 cyl / 6 cyl, california/federal emission? Do you need to replace all of them / one of them / two of them? Why do you think you need to replace them? Are you going to do it yourself?
If you gonna do it yourself, I'd recommend to get Denso universal sensors from rockauto.com. Use code 30253272253617 is "how you heard about us" field during the checkout to get 5% off. You would need to transfer connectors from old sensors to new ones, but no soldering is required: the package contains compression fittings to connect wires.
In general, 4 cyl engine is easier than 6 cyl one (since 6 cyl has one sensor in tight place). But still it is not hard at all.

4 Cyl, California, Not sure but would probably replace all.
The reason I asked how hard to replace them is because a number of people said "It's probably the O2 sensor but I would only replace them if I verified that the O2's were indeed the problem. I would do it myself if that was the case.

Thanks a lot NERVOUS
