• Signal not within the expected value drawn according to 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 as well as the throttle control unit connector. Check that cable resistance between the throttle body connector (PIN 4) and the throttle control unit (PIN 5B) is a few tenths of an Ohm. If this is not the case, restore the cable harness. If the value is correct, replace the complete throttle body.
Rear throttle position sensors P0129 - illogical signal.
Error cause
• Potentiometer 1 and potentiometer 2 do not show a logical value: the sum of the two voltages should be constant. The cause may be a malfunction in one of the two sensors or an ab-normal resistance in one of the two circuits.
Troubleshooting
• Check the throttle body connector as well as the throttle control unit connector. Check that cable resistance between the throttle body connector (PIN 1) and the throttle control unit (PIN 6B) is a few tenths of an Ohm. Check that cable resistance between the throttle body connector (PIN 4) and the throttle control unit (PIN 5B) is a few tenths of an Ohm. If one of the two is different, restore the cable harness. If correct, replace the complete throttle body.
Front throttle Limp Home autodetection P0160 - test failed.
Error cause
• Throttle position, kept by the springs, not within the expected range (at each key ON). The instrument panel does not indicate the presence of this error even in the ATT status.
Troubleshooting
• Check if the throttle body and the intake duct are clean. If they are, replace the throttle body.
Front throttle mechanical springs autodetection P0161 - test failed.
Error cause
• Return time of the throttle, kept in position by the springs, not within the expected limits: the causes can be a deterioration of the performance of the springs or excessive throttle friction (at each key ON).
Troubleshooting.
• Check if the throttle body and the intake duct are clean. If they are, replace the throttle body.
Front throttle minimum mechanical position autodetection P0162 - test failed.
Error cause
• Position of the throttle stop not within the expected range (at each key ON).
Troubleshooting.

• Check if the throttle body and the intake duct are clean. If they are, replace the throttle body.
Detection of front throttle valve Recovery conditions (air Tº,water Tº) P0163 - possible presence of ice.
Error cause
• A correct throttle rotation cannot be detected given low ambient and engine temperatures:
some ice may have formed in the duct (at each key ON). The instrument panel does not indicate the presence of this error even in the ATT status.
Troubleshooting
• Check that the throttle body is clean and that there is no ice or condensation in the intake duct. If they are, replace the throttle body.
Front throttle first self-learning NOT performed P0165 - test not carried out.
Error cause
• The first throttle self-learning process has not been successful or has not been carried out.
The instrument panel does not indicate the presence of this error even in the ATT status.
Troubleshooting.
• Delete errors hindering throttle self-learning.
Front throttle position error P0167 - misalignment between control and activation.
Error cause
• The throttle mechanical control may be damaged.
Troubleshooting.
• Replace the throttle body.
Rear throttle Limp Home autodetection P0180 - test failed.
Error cause
• Throttle position, kept by the springs, not within the expected range (at each key ON). The instrument panel does not indicate the presence of this error even in the ATT status.
Troubleshooting
• Check if the throttle body and the intake duct are clean. If they are, replace the throttle body.
Rear throttle mechanical spring autodetection P0181 - test failed.
Error cause
• Return time of the throttle, kept in position by the springs, not within the expected limits: the causes can be a deterioration of the performance of the springs or excessive throttle friction (at each key ON).
