Lambda Shield stuck heating

Hello,

we had a problem with our lamba shield and the capacitor (C5) broke / snapped from the board during instalation.
We tried soldering it again and we made a test. The shield turns on but the heating led starts blinking and doesn't stop.
I tried opening the software but it just keeps "heating" but is doesn't ever heat.

Any ideas what may be causing this problem? What can we do?

thanks in advance,

Terrigeno Team

Hi!

Unfortunate with the C5 capacitor. Assuming that you have soldered it in place and it is working. It sounds like you are using a non original sensor. Please confirm you are using an original Bosch LSU 4.9 wideband sensor? If it is an original Bosch sensor, please let me know the pnc of it.

Thank you.

Hi Christian,

Uhh, the comments/replies from yesterday are gone?!

Anyway the value has been set on 175 in the sketch,like you said in another topic.(ruling out the SPI part)

The strange thing is the leds indicate heating is done, but serial keeps indicating heating...

Thx,
Kevin

Kevin, I moved the discussion back to SPI thread for better background context.
