anyone help out with engine codes on a 94 456GT. I counted the flaxhes and came up with 1,1,1,3 for cyl. 7 thought 12 and 1,1,2,1 for 1 thought 6. Are the codes two digit or four digit? I think they are two digit, and if so anyone know what codes are 11, 12, & 13? Thanks, John

Codes

I got the code list. There four didgits. They are the same for any car with a Bosch Motronic 2.7 system. code 1113 is the throttle potentiometer. 1121 is the RPM sensor. If any needs a code for the Bosch Motronic 2.7 system let me know. I locked the list in the safe :green:

I have a list here that shows 1121 as RPM sensor as well as Lambda regulation, i.e. both errors are listed wih code 1121
