How to Reset the ECU After Changing an O2 Sensor | It ...

It determines the amount of oxygen in the gases, which indicates how well the fuel is being burned. The O2 sensor then sends information to the electronic control unit, or ECU, the vehicle's computer. The ECU then adjusts the air-to-fuel ratio to optimize the fuel combustion. Sometimes an O2 sensor fails, and you need to replace it. Once you've replaced your vehicle's O2 sensor, you'll need to reset the ECU so it can properly gather information from the new O2 sensor.

How to calibrate a CO2 sensor? - Yoctopuce

· The Yocto-CO2, with its embedded SenseAir K30 sensor. ABC automatic calibration. Automatic calibration is based on the fact that in a common environment, the CO2 level comes back to the norm (400ppm CO2) periodically, at least every few days. Starting from there, the sensor constantly monitors the lowest observed CO2 level over a period of several days. If these lowest values diverge from the norm, the sensor …

CO2 Sensor Calibration: What You Need to Know |

The most accurate method of CO2 sensor calibration is to expose it to a known gas (typically 100% nitrogen) in order to duplicate the conditions under which the sensor was originally calibrated at the factory. ISO certification is available on our high-end sensors to verify this process for medical, research or scientific purposes. Nitrogen calibration is also required if CO2 levels between 0-400 ppm will be …
