I bought an LS1 Scanmaster today and found I had codes P0 171, P0 174, and P0 740. My instructions don't say what these are. I think the instructions I got were meant for a GN.

I did some searching and couldn't find a list, can anybody help me out?

Thanks.

7__ is a tranny code.

Helm's manuals also have the trouble codes in back with explanations.

I want to add an FAQ with all that info good idea?

Thanks John.

Trans code huh...crappola. I just got this trans last spring.

A code list in the FAQ would definitely be a good idea.

EDIT: P0740 is the convertor clutch circuit...probably from my lockup switch.

I have the lean codes 171 and 174 with a 100% stock maf now...I don't get it.

Yeah Jim I get PO740 from my lockup switch too!

You have a vacuum leak of some sort? airbox/intake not sealing properly?
