Firstly Hi,

Right I have a ST170 was driving home last night when the EML came on just as i pulled into the drive, I am used to this however as the car has a full exhaust system on it and no CAT.

Plugged my scanner in expecting it to be about a lambda sensor like normal but no a P1581 came bk unknown fault so googled the code somthing to do with a electronic throttle or something but when i looked under the bonnet my throttle is a cable.

So any help would be greatly appreciated
Thanks James
