4) and the throttle control unit (PIN 21) is a few tenths of an Ohm. If one of the two is different,
restore the wiring harness if ok replace the complete throttle body
Rear throttle valve Limp Home self-acquisition P1400
•
Test failed
Error cause
•
Position of the throttle valve, maintained by the springs, outside the specified range (at each
key ON). The instrument panel does not indicate the presence of this error even in the ATT
status
Troubleshooting
•
Check the cleanliness of the throttle body and the intake duct. If ok replace the throttle body
Rear throttle valve mechanical (re-closing) springs self-learning P1405
•
Test failed
Error cause
•
Throttle valve return time, in the position maintained by the springs, outside of the specified
limits: the causes can be a deterioration of spring performance or excessive throttle valve
friction (at each key ON)
Troubleshooting
•
Check the cleanliness of the throttle body and the intake duct. If ok replace the throttle body
Rear throttle valve minimum mechanical position self-learning P1402
•
Test failed
Error cause
•
Position of the throttle valve stopper outside of the specified range (at each key ON)
Troubleshooting
•
Check the cleanliness of the throttle body and the intake duct. If ok replace the throttle body
Rear throttle valve recovery conditions detection (Tair,Twater) P1403
•
Ice possibly present
Error cause
•
in conditions of low ambient temperature and engine temperature, a correct throttle valve
rotation was not detected: possible presence of ice in the duct (at each key ON). The in-
strument panel does not indicate the presence of this error even in the ATT status
Troubleshooting
•
Check the cleanliness of the throttle body and that there is no ice or condensate in the intake
duct. If ok replace the throttle body
