Throttle Valve Potentiometer (Accelerator Sensor) Check - APRILIA Atlantic 500 Workshop Manual

Electrical Equipment
THROTTLE VALVE POTENTIOMETER
(ACCELERATOR SENSOR) CHECK
With motor off:
• Disconnect the three-way connector (black) (1).
CAUTION
During reassembly ensure correct coupling of the
electrical connector (1).
• Set the ignition switch to " ".
• With a multimeter (scale kΩ), measure the
resistance between the potentiometer terminals.
MEASUREMENT (A)
Resistance between the two terminals A and B, in any
position of the throttle valves:
Standard value: 5 kΩ Ω Ω Ω Ω ± 10%
MEASUREMENT (B)
Resistance between the terminals A and C:
From the value of the throttle completely closed,
accelerating progressively up to completely open, the
resistance will vary as follows:
Standard value: from 1 kΩ Ω Ω Ω Ω to 6 kΩ Ω Ω Ω Ω ± 10%
NOTE
To unscrew the two screws more easily, block
with LOCTITE ® 243, preheat with a blow of hot air.
• Unscrew and remove the screws.
• Remove the potentiometer.
If the resistance values are different from those
prescribed, replace the potentiometer.
