While holding the throttle cable at cam rest position, lock the throttle cable adjuster (1).
Using a scan tool, check the throttle angle. When the accelerator is fully depressed the throttle angle should read 100 percent. When the accelerator is released the throttle angle should read 0 percent. If proper results are not obtained, check cables for kinks or damage and repeat the procedure.
