CHECKING THE THROTTLE POTENTIOMETER

(ACCELERATOR SENSOR)

With the engine off:

• Disconnect the three-way sensor (black) (1).

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 k

ΩΩ

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 k

ΩΩ

Ω - 6 k

ΩΩ

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.
