Default Code 26? QDM Error? WTF

Anybody have any idea what the deal is?

I'm getting a code 26 (Quad Driver Error), and the car stumbles and misses.

I'm also getting a 41 (but I expected that seeing as how the cam magnet is M.i.A)...

I've researched and researched and found absolutely nothing of help on the code 26.

Oh yea its on the 90 Trofeo...


Thanks guys.

Default

I searched on "code 26 quad driver" and found a few threads. Here'* one of the better ones:

http://www.bonnevilleclub.com/forum/...e++quad+driver

Bottom line: Quad Driver Circuit error indicates that the PCM is using default mode to protect itself from a possible fault in a circuit somewhere.

Read the whole thread and then maybe do the same search did for more info.
