Thank you for the information!
I'm going to do some research icon_wink.gif.

However, the main advantage of the relay is that I can switch off the power supply to the GRA using the GRA switch, which causes the relay to drop out. Therefore, even in the event of a malfunction, I can continue driving safely by deactivating the GRA (Gasoline Reduction Assist).

Yes, you're probably right. If the IC burns out, then...
Does anyone know what might happen?

(Engine starting/running)


I hadn't thought of that.

-> Another idea:
If this brief interruption is actually a problem:

A capacitor between the sensor signal and ground.
(The value would have to be determined through testing.)
I would start with 220 or 470uF.

This, of course, also slows down the effect of the accelerator pedal.
However, I think a good compromise can be found.
(You really don't notice 0.1 seconds, do you?)
