Chasing SAS Emission Codes?

DJKapeesh · 10-11-2019, 08:15 AM

Hoping maybe someone can assist me while I attempt to home mechanic the hell out of this thing before my emissions is due in a month!

Long story short
Replaced my DMTL pump on Z4M because I originally got:
p1447 Diagnostic Module Tank Leakage (DM-TL) Pump Too High During Switching
p1449 DMTL voltage high

Reset codes and now getting p1434 (secondary air injection pump relay circuit short to positive) and p1447

Is it actually the air pump this time or fuse?
Or is this me not connecting something properly on DMTL
Or is this OTHER?
