Hi, at first sorry for my english... So, i've got vectra c Z18XE and this night on my way home blinked on me car with key and vectra fell into emergency mode (it was for third time, first time 10 days ago). Engine rpm were beetwen 1300 - 1500, max speed 20km/h.
Diagnostics says
P1500 - Throttle Control Motor Malfunction
(52) - Not present
P1550 - Electronic Throttle Control Power Management
(03) - Not present

Does anybody know, where is a problem? I read that it could be in ECU. I cleaned up throttle control, but still the same problem.

Thank you!
