ISSUE
Some Vehicles may exhibit an inability to reach Wide Open Throttle Mode (WOT). This inability to reach WOT can cause a lack of power condition. This may be caused by the Dash Panel Insulator under the carpet at the accelerator pedal.

ACTION
Use the New Generation Star Tester (NGS) or Worldwide Diagnostic System (WDS) to check for Wide Open Throttle mode. In the KOEO (Key On, Engine Off) mode, depress the accelerator pedal fully and monitor the Throttle Mode PID. If excessive force on the throttle pedal is needed to reach WOT, the Dash Panel Insulator under the carpet may be the cause. Refer to the following Service Procedure for details.

SERVICE PROCEDURE

1. Position carpet to gain access to the area below the throttle pedal.








2. Make a "u-shaped" cut in the insulator below the throttle pedal bracket, 140 mm wide and 100 mm down +/- 20 mm (5.5" wide by 4" down +/- .75"), as seen in Figure 1. Make sure to line up the bottom/center of the "U" cut with the throttle pedal bracket, as seen in Figure 2. This will help relieve any tautness in the insulator, so it will sit flush with the floor panel.

3. Reposition the carpet.

4. Using NGS or WDS, verify that WOT mode can be reached without excessive force on the throttle pedal.
