I know, another check engine/VSC/TRAC OFF thread, but here goes:

P0171
"System to Lean Bank"
P0012
"Cam Position Actuator A - Bnk 1 Timing Over-Retard"
P0441
"EVAP Cntrl System Purge Flow Fault"
P0455
"EVAP System Large Leak"

This appeared on an Actron AutoScanner Plus CP9180. Somehow he made them go away, but I'm afraid they will reappear when it's time to get a new sticker.

I'm new here and see there are other threads that address these things separately, but has anyone ever gotten all 4 at once? Anyone think all 4 can be resolved at the same time by doing one thing. Or at least 2 or 3 at once?

 

This should cover the two EVAP error codes.

Thanks go part. Now I just need to see the service manual to find out how to do something about it.

 

Just reporting back that a smoke test was done and it was found to be a bad purge valve. p0171/0441/0455 now all gone-to my pleasant surprise.

p0012 seems to have disappeared on its own though I know it's unrelated to the others.
