Oxygen Sensor Failure Performance:
Detect the resistance of the oxygen sensor
When the engine temperature reaches normal, unplug the wire connector of the oxygen sensor and use a resistance meter to detect the resistance between the oxygen sensor terminals. The resistance value should meet the requirements of the specific model standard value (generally 440Ω)
Detecting oxygen sensor voltage
Use the fault diagnosis instrument to detect the engine, extract the fault code, and observe the data stream. The operation of the oxygen sensor is judged by the magnitude and frequency of the voltage change of the oxygen sensor. If it is working properly, the voltage should be between 0.4 and 0.6V. If the voltage is always at 0.45V, the oxygen sensor will not work.
Observe the appearance color of the oxygen sensor probe
- Oil pollution: the surface of the probe is covered with a white or gray-black oily deposit on one side.
- Silicon poisoning: probe deposit color between bright white and granular light gray
- Lead poisoning: shiny rust layer on the probe surface
- Antifreeze contamination: a layer of dirt on the surface of the probe
How to install the oxygen sensor?
1.Identify the faulty sensor.
Before beginning, connect the OBD II scan tool to the vehicle and read the codes to determine which specific oxygen sensor has failed and needs to be replaced.Once the faulty sensor has been identified, raise the vehicle and secure it on jack stands. Be sure to raise the vehicle on the side which you will allow you to access the oxygen sensor that needs to be replaced.
2.Removing the Old Sensor.
Disconnect the electrical connection to the oxygen sensor.To remove it, locate the small tab on the end of the plug. While pushing the tab down, pull the plug back by hand.Avoid attempting to cut and then solder the wires to the new oxygen sensor. And then unscrew the oxygen sensor using a ratchet wrench.The easiest way to detach the sensor is by using a 3⁄8 in (0.95 cm) ratchet wrench fit with a 7⁄8 in (2.2 cm) oxygen sensor socket.
3.Installing the New Sensor.
Turn the sensor clockwise to secure it on the exhaust line. Fit the tip of the sensor into the hole on the exhaust line. Make sure it is centered and goes in smoothly as you begin rotating it clockwise by hand. Once it is tightly in place, use an oxygen sensor socket or open end wrench to give it a final turn.And then plug the electrical connector back into the vehicle. The cable will be hanging from the free end of the sensor. Plug it into the outlet port close to the exhaust line.Push the plug in until it snaps into place. Make sure the cable isn’t touching the engine or other parts that heat up when the vehicle is in use.
4.Start the vehicle.
Start the car to see if the problem is fixed. In some vehicles, you may need to clear the check engine light manually. Shut off the engine, then turn the car’s power on using the ignition key. Use the delete feature on an OBD code scanner to reset the light.Disconnect the battery or take the vehicle to a mechanic for additional ways to shut off the check engine light.If the check engine light comes back on, either the oxygen sensor wasn’t installed correctly or your vehicle has another problem.

I had a P0420 code. Decided to give the sensor shot. Instead of replacing the catalytic converter. When I put this censor it threw off about five other codes, besides the P0420. I put the old one in and I was down to one code again.

No puedo decir si el producto es malo o bueno. No sería justo. Pero lo que si puedo decir es que este producto el vendedor o Amazon lo tienen como exacto para Camry 2004. Y no es cierto. Debe funcionar para otro modelo. Pero no para un Camry 2004 XLS. No les recomiendo. El mecánico lo probó y genera oscilación. No sé sabe si es daño o simplemente no es compatible para este carro

I bought this after the check engine light coming on in our 2003 Toyota Camry LE with. 2.4 liter engine. We had the part sent to our daughters place an hour away since we live in quite a rural area. I had contacted our local Toyota dealership to confirm I was dealing with the correct sensor and got the right part number from them. I also was away for the better part of a week with work. But after installing the new sensor and clearing the codes then the codes immediately reappear and are telling me this sensor is the problem. Quite disappointed. I am hoping they will send another one.

My 2004 camry Showed a p0420 message. I found there are three oxygen sensors for my car, one is this air fuel ratio sensor. Another two are after each catalytic converters. Maybe because we're in calie, there are twk catalytic converters. After replacing the air fuel ratio sensor, p0420 went away.
