The frequency increases as the

ECU vehicle speed information.

Wide Open
Throttle (WOT)
The vehicle operating condition
brought about when the throttle
is completely (or nearly so)
open. The ECU typically
delivers extra fuel to the engine
at this time for acceleration
purposes. The ECU uses the
Throttle Position sensor, or a
switch, to identify the WOT
condition.
