Hazardous Gas Monitor -

Once you have the sensor voltage, you can convert that into a parts per million ("PPM") reading using the sensitivity calibration curve on page 5 of the gas sensor datasheets. To do this, recreate the sensitivity curve by picking data points from the graph or using a graphical analysis software like Engauge Digitizer. Plot PPM on the y-axis and V_RL on the x-axis, where V_RL is the sensor ...

Dealing With Sensitive Types: Toyota A/F Sensors | MOTOR

If you believe a rear O2 sensor issue underlies an excessive fuel trim correction, you can remove the PCM battery fuse to clear the KAM, temporarily resetting the rear O2 sensor’s trim to zero. However, this will also clear codes, erase freeze-frame memory and reset any monitor information, so you’ll want to make sure you’ve read and recorded all of that before taking this step.
