73 Volvo TPS

Yes, Norbert, it seems that now it is cleared up.

On the Volvo, we use 14 and not 12. So the correct order from top down is 9/20/14/17 and the last pin is unused. I have connected the pins in this order and I have continuity, and the TPS seems to be working well. The middle pin is 14.

However, I am not able to hear the series of 18-20 clicks when I open the throttle manually. I can't understand why I am not able to produce the clicks.

Thank you for your guidance.

Hi Mitch,
just read the signals out.
Read the continuity between Pins 14 and 20 while you open the throttle extremely slow.

Maybe there is another reason for the injector-clicks missing than the tps...

OK, I will try this. Thanks

Between pins 14 and 20 I read 11 continuity beeps when moving the throttle.
Is this less than normal?

It`s working o.k.

Good to know.
Thank you again for your help Norbert.
