High idle is dictated by readings from the following sensors:
- IAT (Intake Air Temperature): High idle setpoint (up to 1300 RPM's) is determined by air temps.
- EOT (Engine Oil Temperature): Oil must be below 122* F to increase idle.
When you start your truck in the morning it is normal that is the EBP valve will start operating. It applies a light load to the engine to help it warm up quicker. it will deactivate when you hit brake or go pedal or when your truck gets to operating temperature.
