•
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 OK, replace the throttle body
Rear throttle power supply voltage during self-learning P0164
•
low supply voltage
Error cause
•
The throttle power supply voltage is too low to carry out the self-acquisition test correctly (at
each key ON). The instrument panel does not indicate the presence of this error even in the
ATT status
Troubleshooting
•
Delete errors hindering throttle self-learning.
Rear throttle position error P0167
•
misalignment between control and activation
Error cause
•
The throttle mechanical control may be damaged
Troubleshooting
•
Replace the throttle body
Front throttle Limp Home self-acquisition P0180
•
failed test
Error cause
•
Throttle position, kept by the springs, not within the expected field (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 OK, replace the throttle body
Front throttle mechanical springs self-acquisition P0181
•
failed test
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)
