Note:
For safety reasons, the instruction from the
accelerator pedal sensor (potentiometer) to the
ECM to open the throttle valve is suppressed
when brake is being operated. This requires the
brake light switch signal and also the brake pedal
switch signal in the control module. If brake pedal
is operated with accelerator pedal constantly
depressed, engine is immediately regulated
down to idle speed. A faulty switch can lead to
undesired regulation.
