Stupid Question....Throttle Return Spring?
Where is this located? Just looking over a tech form and noticed it asks about throttle return springs being able to returns without problem.
Is there even a throttle return spring on an e-gas car? TIA! :cheers: |
"The position of the throttle is controlled by a digital position controller which emits a pulse-width-modulated (PWM)
duty cycle and a direction bit. After the output stage has been deactivated, the throttle is brought into emergency air position by means of two springs. This return of the throttle must take place within a certain time. If this time is exceeded, a fault is stored in the memory." |
Thanks J. So it sounds like throttle return springs are items we see on non e-gas models and motors like carbureted ones, correct?

Dell, to be honest I haven't completely disassembled the accelerator pedal , but by reading the WM it seems that both versions (E-GAS or not) have an assisted operation return.
Generally speaking two springs are common in accelerator pedals the second one probably serving as a back up.. |
I once asked my mechanic to give me a backup return spring for my '04 GT3. He laughed and said that the GT3 doesn't have them.
The answer wasn't completely satisfying to me because we clearly are pressing against a resistance so there MUST be a spring or something in there somewhere, but apparently there is no spring like in the olden days. |

I have no idea how it's actually done in the GT3, but it's typical that electronic foot pedal assemblies have two nested torsional springs installed around the pedal pivot shaft. |

Dell, what are you driving these days, and why is your accelerator pedal not returning? |
Chris, I'm driving a pseudo GT3 with back seats, a front diff, and two turbos :)
By the way, my accelerator is fine. I was just reading a tech form and it stated to check it. I had no idea where to check :surr: |
Cool!

there may be one or more in the pedal assembly but here is one in the cable...see #3
