Electrical system
CHECKING THE THROTTLE POTENTIOMETER
(ACCELERATOR SENSOR)
With the engine off:
• Disconnect the three-way sensor (black) (1).
CAUTION
On reassembly, make sure that the electric con-
nector (1) is correctly coupled.
• Set the ignition switch to " ".
• Use a tester (scale kΩ) to measure the resistance
between the potentiometer terminals.
READING (A)
Resistance between the two terminals, A and B,
whatever the position of the throttle:
Standard value: 5 kΩ Ω Ω Ω Ω ± 10%
READING (B)
Resistance between the terminals A and C:
From the reading with the throttle completely closed,
progressively accelerating until it is fully open, resis-
tance will vary as follows:
Standard value: from 1 kΩ Ω Ω Ω Ω - 6 kΩ Ω Ω Ω Ω ± 10%
NOTE
To make unscrewing the two screws easier,
lock with LOCTITE ® 243 and heat first with a jet of
warm air.
• Unscrew and remove the screws.
• Remove the potentiometer.
If the resistance values are different from those
prescribed, replace the potentiometer.
