Check the throttle body connector and the control unit connector. Check that the resistance
of the cable between the throttle body connector (PIN 1) and the control unit (PIN 48) is a
few tenths of ohm. Check that the resistance of the cable between the throttle body con-
nector (PIN 4) and the control unit (PIN 50) is a few tenths of ohm. If one of the two is different,
restore the wiring harness if ok replace the complete throttle body
Front bank throttle valve position potentiometer sensor P0221
•
Signal not plausible
Error cause
•
Signal outside the specified value determined based on the values of the intake pressure
Troubleshooting
•
Check the parameter of the Potentiometer 1 rear throttle (voltage) to get which signal the
control unit receives and to compare it to the Potentiometer 1 front throttle (voltage). Check
the throttle body connector and the control unit connector. Check that the resistance of the
cable between the throttle body connector (PIN 1) and the control unit (PIN 36) is a few
tenths of an ohm. Otherwise, restore the wiring harness if ok replace the complete throttle

•
Signal not plausible
Error cause
•
Signal outside the specified value determined based on the values of the intake pressure
Troubleshooting
•
Check the parameter of the Potentiometer 2 rear throttle (voltage) to get which signal the
control unit receives and to compare it to the Potentiometer 2 front throttle (voltage). Check
the throttle body connector and the control unit connector. Check that cable resistance be-
tween the throttle body connector (PIN 4) and the throttle control unit (PIN 21) is a few tenths
of an Ohm. Otherwise, restore the wiring harness if ok replace the complete throttle body
Throttle valve position sensors CF2 P2138
•
Signal not congruent
Error cause
•
Potentiometer 1 and potentiometer 2 do not provide a congruent value: the sum of the two
voltages must be constant. The cause could be the malfunction of one of the two sensors
or an abnormal resistance in one of the two circuits
Troubleshooting
•
Check the throttle body connector and the control unit connector. Check that the resistance
of the cable between the throttle body connector (PIN 1) and the control unit (PIN 36) is a
few tenths of an ohm. Check that cable resistance between the throttle body connector (PIN
