Logitech G920 throttle pedal issue

[TheDreamlord]

Hey there racing fans.

My Logitech G920 just started having an issue with the throttle pedal. It doesn’t seem to depress back to 0 when my foot is off it. Essentially, games seem to think that I am slightly pushing the pedal (something like 5%) but I am not touching it.

I tried it with three games and it happens on all three, so it must be an issue with the pedal rather than the game or the settings.

Any ideas what this can be and how it can be detected/fixed?

If you’ve already calibrated the pedals, then I would suggest giving them a good clean. Pedals are famous for picking up a lot of dust, and potentiometers suffer from build-ups.

[TheDreamlord]

Hmm. How would I do that? I guess I need to unscrew it open? This will probably void the warranty.
Also, I just thought about it, can I increase the dead zone on the throttle pedal and sort the problem this way?

Edit: also, by pedal calibration, you mean in the game? If so, yes, they’ve been calibrated for each game individually. Is there a utility (the Logitech Gaming Software doesn’t seem to offer any calibration options) to do check the calibration of the whole set?

Edit 2: I checked under Windows 10’s Devices and the controller properties, and indeed the problem seem to be the throttle pedal. The minute I push it a bit, it does not go back to zero, but it madly goes up and down between 0 and 15%. I guess you are right that I might have to clean it. Unless it might be something else? I think I am still within warranty period.

The wheel is calibrated as soon as the various controls are used after plugging in. So, for the pedals, you need to press fully down each one of them and return them to the starting position.

Logitech has a pretty amazing warranty policy but I’m not sure they will replace the wheel only because of that. Of course, it doesn’t hurt to try.

[TheDreamlord]

Yeah, I just raised a warranty case with Logitech, I’ll see what happens.

After some googling I found out that the problem is called ‘spiking of the pedal’ and is caused by dirt in the pedal’s insides and in the potentiometer itself.
If Logitech won’t do anything, I’ll open it up to clean it, I found this very good video that has instructions on how to do it.

If eventually you open the pedal set, may also want to apply the tennis ball or similar fix to improve the feel of the brake.

If all fails, you can always crank up the dead zone to the first 5%. You lose precision but at least it remains functional.

[TheDreamlord]

Well, I fixed it. I opened it up, cleaned the potentiometer and also switched the gas pedal pot with the break petal pot. I never use the break, because of its stiffness, I have switched the break and clutch pedals and I always use automatic gears anyway. So, all sorted. Hopefully it will last another year or two.

The pots only really need cleaning from time to time, their long term reliability shouldn’t be impaired.

It’s just unavoidable that they collect dust over time and the specifics of the construction, at least for all of those I had dealt with, just lend to that problem.

Once the dust is gone, the pots go back to their usual operation. You may want, however, to lube the pedal mechanism.

Regarding stiffness, isn’t that just a matter of springs?

@TheDreamlord Did you do everything in that video? My pedals are doing it but im really scared to do that video

[TheDreamlord]

Yup, I did and it works fine since then.

[Nascarfan1491]

Ok thank you so much. I will try it hopefully everything goes well

[TheDreamlord]

Good luck! The other thing I did was to swap the damaged potentiometers from the affected pedal with the clutch ones, since I never use the clutch.

Hi! I’ve had some issues with the pedals on my G920.

The first one is that the throttle input flickers - sometimes it doesn’t go back to 0% input when I fully let go of it, usually it flickers when pressed not fully, and when fully pressed, unless I press the top of the physical pedal, the input doesn’t go to 100% consistently.

The second issue is that the brake glitches out when I press the throttle. Basically. when the issue is present, pressing the throttle pedal while not touching the brake at all gives random/flickering inputs. If I tap the brake, the issue goes away until I press the brake again (obviously that is soon after the tap in racing games).

The first issue isn’t that much of a problem as the pedals can still be used with deadzone on the throttle, but it’s annoying.
The second issue, though, makes the pedals practically unusable for obvious reasons.

Please leave suggestions and solutions if you have had this problem and fixed it/know how to fix this.

I had the same issues in the past. Look here:

You need to either clean or replace the potentiometer on the pedal or pedals that are having issues.
