is not engaged, at approximately ???? rpm the throttle valves opening s very small and the requested
torque is very low (approximately 5-7°)
Potentiometer 2 rear throttle valve (degrees)
•
Example value with key ON: 8.2°
•
Example value with engine on: 1.6°
With key set to ON, the throttle is kept in position by the springs (around 5 -7°). After the engine starts
up at idle, the throttle is kept close to the mechanical minimum (above or equal to 0.5°). When the gear
is not engaged, at approximately ???? rpm the throttle valves opening s very small and the requested
torque is very low (approximately 5-7°)
Front cylinder throttle valve Limp Home position
•
Example value with key ON: 878 mV
Voltage stored in the control unit corresponding to the Limp home position
Rear cylinder throttle valve Limp Home position
•
Example value with key ON: 888 mV
Voltage stored in the control unit corresponding to the Limp home position
Front throttle valve lower position
•
Example value with key ON: 502 mV
Voltage stored in the control unit corresponding to the throttle mechanical minimum position
Rear throttle valve lower position
•
Example value with key ON: 492 mV
Voltage stored in the control unit corresponding to the throttle mechanical minimum position
CAUTION
BEFORE CARRYING OUT ANY TROUBLESHOOTING, CAREFULLY READ THE GENERAL TROU-
