Electrical Actuated Throttle error P1689 FATAL
"P1689 Electrical Actuated Throttle (self compensate) Invalid Signal store FATAL Light On".
That's the message Multiecuscan throws up after I investigate the 'Motor Control System Failure - Go To Dealer' message.
It also showed P1688 Electrical Actuated Throttle (idle learn2) but that one went away after I hit 'Clear Errors'. P1689 remains however.
The car runs perfectly but I would like to get rid of the nag light and message if possible.
If anyone knows to what these errors refer and how to fix them, I would, as always, be grateful for the help.
ps I've done a Forum Search for these two error codes but have drawn a blank.
