I'm a newbe at the svx code thing, I would start by clearing the codes as per instructions and see if they both come back. then proceed from there, I have had a few codes show up and after clearing some came back (knock sensor) (maf)some did not, after replacing the ks and cleaning the maf no codes. This doesn't help your situation but gives some info to work with, I know little about the TCU ECU realationship.................G
