MAXFAVOR dedicated to provide the good selection, the latest cutting edge technology, and the good overall shopping experience. Maxfavor oxygen sensor features double protection layer, aluminum oxide trap layer, porous PTFE filter and stainless steel housing. It is manufactured with precision to meet OE standards and can be installed easily and ensures longevity.
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

I drive a 2016 Ford Transit Connect. Although the check engine light turned off, I was still unable to pass the smog check in California because the O2 sensor heaters never activated. After replacing the sensors with Bosch, everything began functioning properly. Based on this experience, I wouldn’t recommend these sensors—unless your only goal is to clear the check engine light.

Seems lije a good price for two sensors, had to take my rig to a service shop as the old ones were rusted in tight. It will be a few miles before i discover if they’re any good or not
