Example value:
short circuit to positive / open circuit, short circuit to negative
Error cause
•
If shorted to positive: excessive voltage has been detected at PIN A5 of the throttle control
unit. If the circuit is open, shorted to negative: voltage equal to zero has been detected at
PIN A5 of the throttle control unit.
Troubleshooting
•
shorted to positive: check the value shown by the parameter of the front throttle Potentiom-
eter 2 (voltage): disconnect the left connector and see the value displayed by Navigator: 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, shorted to negative: check the throttle body connector and the throttle
valve connector. If not OK, restore; if everything is OK, check circuit continuity between the
two terminals. If not OK, restore the cable harness; if OK, check the circuit ground insulation
(from throttle sensor connector or control unit connector). If it is ground 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.

Example value:
short circuit to positive / open circuit, short circuit to negative
Error cause
•
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.
