Performed/Not performed
Indicates if the self-learning with the diagnostic tool was performed/not performed: if it was performed
one time, it will always remain performed unless a control unit EEPROM reset is carried out
DIAGNOSTIC TOOL: ELECTRICAL ERRORS
CAUTION
IF ERRORS ARE DETECTED ON BOTH THROTTLE BODIES, CHECK ALSO THE CORRECT SUP-
PLY OF THE CONTROL UNIT TO PIN 42.
Rear bank throttle valve position potentiometer sensor P0120
•
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 shown by the parameter of the Rear throttle Po-
tentiometer 1 (voltage): disconnect the connector and read the value indicated in the
diagnostic tool: if the voltage does not vary, there is a short circuit of the cable, if the voltage
goes to zero, replace the throttle body
•
If open circuit, short circuit to negative: check the throttle body connector and the control
unit connector, if not ok restore, if everything is ok check the continuity of the circuit between
the two terminals, if not ok restore the wiring harness, if ok check the ground insulation of
the circuit (from the throttle valve sensor connector or control unit connector), if ground
insulated, check that the power supply (+5 V) is present at PIN 2 of the throttle body con-
nector and that ground is present at PIN 6, if present correctly replace the throttle body
Rear bank throttle valve position potentiometer sensor CF2 P2120
•
short circuit to positive / open circuit, short circuit to negative
Error cause
•
Short-circuit to positive: excessive voltage has been detected on PIN 50. If open circuit, short
circuit to negative: voltage equal to zero detected at PIN 50
Troubleshooting
•
Short-circuit to positive: check the value shown by the parameter of the Front throttle Po-
tentiometer 2 (voltage): disconnect the connector and read the value indicated in the
diagnostic tool: if the voltage does not vary, there is a short circuit of the cable, if the voltage
goes to zero, replace the throttle body
•
If open circuit, short circuit to negative: check the throttle body connector and the control
unit connector, if not ok restore, if everything is ok check the continuity of the circuit between
the two terminals, if not ok restore the wiring harness, if ok check the ground insulation of
the circuit (from the throttle valve sensor connector or control unit connector), if ground
