check for physical damage
checking for nominal resistance
Measure resistance between terminals T and U.
Nominal resistance:
Measuring of resistance across turning range of fitted throttle.
To check the function of the throttle position potentiometer over operating
range take the following readings:
Resistance between the terminals Y and U:
Throttle closed (throttle lever pos. 0%): 3,4 ÷ 4,6 kΩ
Throttle open (throttle lever pos. 115%): 0,8 ÷ 2,0 kΩ
closed
Resistance between the terminals T and Y:
Throttle open (throttle lever pos. 115%):
Throttle closed (throttle lever pos. 0%):
ATTENTION: Parts physically damaged or of not correct function have to
be exchanged without delay.
Reference
3,2 ÷ 4,8 kΩ
Check complete operating range
as per diagram (Pic. 179) for lin-
ear resistance progress.
