VSC and CEL
Hey guys,
I think I might have fixed my evap leak (P0440 and P0442). Three fixes I believe caused this (loose fuel sending assembly, cracked vacuum hose and a unclamped fuel line), two of which were caused by an unprofessional fuel pump replacement. I cleared the CEL by disconnecting the negative terminal on the battery and have since driven 75-100 miles. The CEL has not come back on but the two VSC lights are still on. How can I get rid of these? A Zero Point Calibration maybe?
TIA

The CEL comes on along with the 2 VSC lights indicating a emissions issue/problem. I already fixed the issue and cleared the code by disconnecting the battery but the VSC lights stayed on. I cleared them by performing a zero point calibration already. Thanks though.
