Introduction

The potentiometer is responsible for getting a reading of the extent that the pedal is being pressed, while the potentiometer connections and cable is responsible for relaying this info to the computer/application. Therefore either or both of these components can result in inaccurate readings from the pedal.

Before beginning, make the sure pedals are unplugged from the wheel.

What you need

Step 1

              How to Fix Faulty Logitech G29 Pedals

Remove the four 30 mm screws from the left and middle pedals using a 1/8 hex key.
Remove the two 16.3 mm screws from the right pedal using a 1/8 hex key.
Pull the silver pedal plates off of each pedal.

Step 2

Flip the pedal set over so it is facing down.
Remove twelve 15.8 mm screws from the bottom using a Phillips #1 screwdriver,
Remove two 15.8 mm screws hidden behind the rug grip using a Phillips #1 screwdriver.
These metal screws are screwed into plastic, so do not overtighten them when reassembling, or you might strip the anchor points.

Step 3

Slowly and carefully lift the top housing up from the set.
Do not pull the top housing too far, as a cable is anchored to the top housing, which needs to be unscrewed in the next step.

Using a Phillips #1 screwdriver, remove two 7.4 mm screws that hold the cable to the top housing.

Step 5

Flip the pedal set onto its side.
Each pedal is held in place with four screws.
Using a Phillips #1 screwdriver, remove the four 15.8 mm screws corresponding to the pedal you want to fix.
In this guide, I will be working on the gas pedal only. The process is the same for each pedal.
Once the four screws are removed, you can remove the pedal from the base to get a clearer view and access to the potentiometer and its connections.

Step 6

The color of the wires are different for each pedal. Keep note of the color of the wires, and which goes where.
Using a Phillips #1 screwdriver, remove the single 6.2 mm screw holding the ground ring in place.
Using a pair of pliers, remove the three connections carefully.
When pulling on the three connection points, there may be some resistance. Do not pull too hard; if you yank on the cable too hard while it’s out, it might damage the cable itself.

Step 7

Check the terminals for any debris or particles that might be in the way. Ensure the terminals are clean so that the connection is not interrupted.
Check the ground ring and where it connects to make sure no debris or particles are in the way. The ground ring needs to be directly touching the metal on the pedal for it to work properly.
If the connections are dirty, wipe them using isopropyl alcohol.

Step 8

Reinsert the wires into the terminals.
Make sure the wire fits all the way in, as shown in the second picture.
If the connection still feels somewhat loose or shaky, squeeze the connection a little bit to make it more tight, ensuring it wont undo itself over time.

Jeremy thank you so much for the information very helpful. I have a question what if I was wanting to have my throttle to run wide open when I get off the throttle and decelerate when I push down on the throttle kinda like a dozer there for not wanting to have to push on the throttle all the time

Jeremy Sukhai - Dec 13, 2022

This could be achieved through software rather then altering the pedals itself. Most games or software will provide you with options to customize the functionality of pedals, that way you can invert the input so 0input=full throttle and 100input=no throttle. If you cant do this through software, you could swap the 5v and ground connections which are the connections not in the middle. This will reverse the voltage reading for the potentiometer, then the throttle will be wide open by default, and decelerate when you press the pedal.

Thank you Jeremy so much I will try to do this.
