1989 has one oxygen sensor. 1996 and up have two, three, or four. Depends on which engine and exhaust system you have.

- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 1 circuit poor electrical connection

- Faulty Engine Control Module (ECM)
Tech notes The code means that there is a problem with the heater element circuit of the heated oxygen sensor. The Engine Control Module (ECM) monitors how long it take the sensor to warm up and start sending an adequate signal. The code means the the sensor is taking too long to warm up. Replacing the O2 Sensor 1 usually takes care of the problem

1998 Toyota Camry replaced O2 sensor reset code and now it is on again

Are you sure the O2 sensor is what is causing the light to come on? Code 21 is Oxygen sensor. Sometimes another fault can cause the computer to think it is the oxygen sensor. Such as when you have a misfire, causing the sensor to read rich, or when the MAP sensor is faulty, causing a rich or lean condition.
Also, did you replace the sensor with a new one? Or second hand? Replacing with a second hand sensor is bad practice as they typically have a service life of 100k miles. If you replaced the sensor with an aftermarket type, it could be the wrong one, thye all have different resistance values for the heating circuit & the computer uses this resistance value to determine if the sensor heating circuit is faulty.

How many o2 sensors does my 98 camry v6 has?

There are 2 sensors. The main one is located in the exhaust manifold (facing you as you look at the engine from the front of the car). The secondary sensor is located behind the catalytic convertor, which is under the car, approximately beneath the front passenger seat. On some cars, somewhere around 1999, Toyota started using an air/fuel sensor instead of an oxygen sensor in at least one of these locations, so you need to be sure which one you have before replacing. They are not interchangeable.

Find get at the wire and plug for the oxygen sensor on 2001 toyota camry 4-cyl

Unbolt the pass side seat (only 4 14mm head bolts) and lay it back. This will give you the room you need to pull the carpet back from the console area and get to the plug.
