Complementary Modification:

Clean throttle body

Most modern cars these days no longer use a mechanical link from the gas pedal to the throttle body. What is commonly used is an electronic device that measures the position of the pedal and then sends a signal to the throttle body. This signal causes the motor in the throttle body to open and close. This is commonly referred to as "drive by wire". Over time, these modules can fail, leaving you stranded on the side of the road.

The good news is that the module is easily replaced in under an hour. In this article, I'll go over the steps involved with changing the module. I recommend disconnecting the battery before you begin. This is a safety factor that you should follow whenever unplugging a control module from the car. Please see our article on battery replacement for more information. You'll also need to remove the lower dashboard panel to gain access. See our article on Lower Dashboard Panel Removal for more information.

The accelerator pedal module is held in place by three 10mm nuts.
Figure 1

The accelerator pedal module is held in place by three 10mm nuts. Loosen and remove the bottom-mounting nut (green arrow) near the physical gas pedal.

The two upper mounting nuts can be a little difficult to see (green arrows).
Figure 2

The two upper mounting nuts can be a little difficult to see (green arrows). You'll need to use a long extension with a 10mm socket to loosen and remove the upper fasteners.

Once the mounting nuts are removed, lower the pedal assembly down from the firewall.
Figure 3

Once the mounting nuts are removed, lower the pedal assembly down from the firewall. Squeeze the two plastic tabs (green arrows) on the electrical connector and pull it out of the pedal assembly.

The last step is to remove the dashboard panel locator piece from the old pedal assembly and transfer it to the new one.
Figure 4

The last step is to remove the dashboard panel locator piece from the old pedal assembly and transfer it to the new one. Squeeze the two locking pins (green arrows) together and slide the locator out of the pedal assembly. Now transfer the locator to the new pedal assembly and snap it in place. The remainder of the job is the reverse of removal.
