Detect the resistance of the 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 color of the sensor probe
- Oil pollution: the surface of the probe is covered with oily deposit
- 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

Item was as described and fixed my truck

I had on my truck for two week, and had to remove due to check engine light coming on, replaced with Bosch sensors truck run fine again and dash light is off. I was going to return but of course two weeks past return policy.

I installed these O2 sensor with a new exhaust system to my 2006 Chevy Silverado 4.3 L. I cleared all the codes and lo and behold a few minutes into driving the engine light came back on. This then caused the truck to idle through extremes of rich and lean fuel mixer.

Even with new catalytic converter still trips O2 codes sensor code.

I only got 1 out of the 4 sensorsâŠ.. wow
