I'm not sure why you would come into a topic about radio auxiliary
& ask a question about fault codes ???

here is your answer , & if you have any more questions the search
feature is your friend , Or you can make your own topic .

This topic has nothing to do with fault codes
So please keep your questions out of this topic !!!

P1890 trans control usually caused by low or unusual voltage ,
Also Speed change control linear solenoid valve failure &
Transmission failure .
