may be the lambda sensor is broken ? or your controller ?

Thank you Ali,

10325 (0x28FF) is the status for no power.

79 in this case shows that the Arduino is measuring 4.3V.

Is there a problem with the 12V power supply or connections?

i measured the voltage while running. 12.4 V so should be fine. i changed the jumper but still nothing changed.

There is no power to the Lambda Shield, the jumper will not affect that.



If possible please check if you have power on these points, before and after the protective diode.

i have 11.8v and 12.6v engine not running

is there any solution ?

Great Ali, then we know there is power on the shield from the power supply.

I will send you a new shield to test with, you will receive the tracking number by email. If it works you can return the old one for me to analyze.

Thank you.

Nothing helped.

still stuck at loading screen. the last thing i will change is the lambda sensor again.
it should arrive next week. sometimes it will show me the loading screen and sometimes nothing. after multiple restarts it will show me the loading screen. standard code from GitHub

Hello Ali. The Lambda Shield 2 that I sent you is 100% working so if it is not working, there is a problem with something else. We need to find this problem. Can you please disconnect everything else connected like displays and only test Arduino, shield, sensor and power supply. Please share the output.

Thank you.
