THROTTLE VALVE POTENTIOMETER

(ACCELERATOR SENSOR) CHECK

With motor off:

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

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 k

ΩΩ

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 k

ΩΩ

Ω to 6 k

ΩΩ

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.
