Electronic Accelerator System Schematic
Warm-up Control Function
The warm-up control is effective at all engine temperatures. After each start-up (accelerator pedal in idle position) the engine increases the idle
speed for approx 20 seconds. Below 20 °C (68 °F) the engine speed is 900 - 1000 RPM.
A/C engagement Control Function
When the A/C compressor is turned on, the throttle valve opening is increased before the A/C compressor engages. This keeps the engine idle
speed at a nearly constant RPM.
