tinuity of the circuit between the two ends; if not ok, restore the wiring harness, if ok, check
the ground insulation of the circuit (from the throttle body connector or control unit connec-
tor); if ground insulated, check that at PIN 2of the throttle boy connector there is power supply
(+5 V) and that at PIN 6 there is ground; if they are correct, replace the throttle body.
P0220 Front throttle valve position potentiometer sensor
Electrical diagnosis:
•
Short circuit to positive / open circuit, short circuit to negative.
Error cause:
•
Short-circuit to positive: excessive voltage has been detected on PIN 48. If open circuit, short
circuit to negative: voltage equal to zero detected at PIN 48.
Troubleshooting:
•
Short-circuit to positive: check the value indicated by the Potentiometer 1 front Throttle valve
parameter (voltage): disconnect the left side connector and read the value indicated in the
diagnostic tool: 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 open circuit, short circuit to negative: perform the check procedure for the throttle body
connector and control unit connector; if not ok, restore, if everything is ok, check the con-
tinuity of the circuit between the two ends; if not ok, restore the wiring harness, if ok, check
the ground insulation of the circuit (from the throttle body connector or control unit connec-
tor); if ground insulated, check that at PIN 2of the throttle boy connector there is power supply
(+5 V) and that at PIN 6 there is ground; if they are correct, replace the throttle body.
P2125 Rear throttle valve position potentiometer 2 sensor
Electrical diagnosis:
•
short circuit to positive / open circuit, short circuit to negative.
Error cause:
•
Short-circuit to positive: excessive voltage has been detected on PIN 21. If open circuit, short
circuit to negative: voltage equal to zero detected at PIN 21.
Troubleshooting:
•
Short-circuit to positive: check the value indicated by the Potentiometer 2 rear Throttle valve
parameter (voltage): disconnect the left side connector and read the value indicated in the
diagnostic tool: 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 open circuit, short circuit to negative: perform the check procedure for the throttle body
connector and control unit connector; if not ok, restore, if everything is ok, check the con-
tinuity of the circuit between the two ends; if not ok, restore the wiring harness, if ok, check
