•

sensor: on the right cylinder throttle

body

•

connector: on the potentiometer

Electrical characteristics:

PINS A-C: throttle closed approximately 1.7

kOhm; throttle open approximately 1.1 kOhm.

PINS A-B: approximately 1 kOhm.

Pin-out:

A: ground connection

B: supply voltage +5V

C: potentiometer signal (from 0.5 V with closed

throttle to 4 V with open throttle)

AXONE: PARAMETERS

Potentiometer on throttle / 0.5 (minimum) - 4 (full load)

Correct throttle position / 3.1 (minimum) - 85 (full load)

AXONE: STATUSES

Minimum/full load - ON/OFF

If the throttle is at minimum, it indicates ON, if the throttle is out of minimum, it indicates OFF

AXONE: ELECTRICAL ERRORS

Throttle - open circuit, shorted to positive / shorted to negative.

Error cause

•

If the circuit is open, shorted to positive: excessive voltage has been detected at PIN 11 of

the control unit connector.

•

If shorted to negative: voltage equal to zero has been detected.

Troubleshooting

•

Circuit is open, shorted to positive: check the injection control unit connector and the sensor

connector: if they are not OK, restore; if they are OK, check the continuity between PIN 11

of the control unit connector and PIN C of the sensor (brown/yellow cable): if there is not

continuity, restore the cable harness; if there is continuity, check continuity of the sensor

between PIN A and PIN C: if there is not continuity, replace the potentiometer; if there is

continuity, measure the resistance. If resistance is over 2 kOhm, it indicates the brown/yellow

cable is shorted to positive; therefore, it is necessary to restore cable harness

•

if shorted to negative: disconnect the sensor connector and check the ground insulation of

the brown/yellow cable (from throttle sensor connector or control unit connector): if there is

continuity with the ground connection, restore the cable harness; if earth insulated, the re-

sistance between PIN A and PIN C is below 1.3 kOhm; therefore, it is necessary to replace

the throttle body.
