Calibrated the sensor today, the big plastic plug that you connect to the sensor has a little plastic tab if you connect the plugs without lifting it then it can very easily go the wrong side of the plug. That stops it connecting up properly which this one did first few times I tried.
I put the power on with the sensor disconnected which puts it in calibration mode. Unplugged the power and plug in the lambda sensor then put the power back on. The sensor gets quite hot, you can see it glowing here inside:
It showed HTR on screen while it warmed up. My bench power supply showed between 1.4 and 1.7 amps being pulled while it was warming up.
It briefly showed CAL is the display while calibrating then switched to 22.4 as it is in free air:
Now ready to install when its dry enough to drive over to the garage with all the tools
