•

If shorted to positive: excessive voltage has been detected at PIN B6 of the throttle control

unit. If the circuit is open, shorted to negative: voltage equal to zero has been detected at

PIN B6 of the throttle control unit.

Troubleshooting

•

if shorted to positive: check the value shown by the parameter of the Front throttle Potenti-

ometer 1 (voltage): disconnect the left connector and see the value displayed by Axone: if

the voltage does not vary, there is a short circuit in the cable wiring; replace the throttle body

if the voltage drops to zero.

•

if the circuit is open, short circuit to negative: check the throttle body connector and the

throttle valve connector. If not OK, restore; if everything is OK, check circuit continuity be-

tween the two terminals. If not OK, restore the cable harness; if OK, check the circuit earth

insulation (from throttle sensor connector or control unit connector). If it is earth insulated,

check that there is power (+5 V) at the throttle body connector PIN 2, and that PIN 6 is

connected to ground. If both are correct, replace the throttle body.

Potentiometer 2 sensor, rear throttle position P0127

Example value:short circuit to positive/ open circuit, short circuit to negative
