My wife was roaming around in the Disco II today and the SES light came on. I just pulled the codes and I got:

P1412 - Aux Emmission Controls
P1415 - ???
P0455 - EVAP Emmission Control System Leak (Large)

Any ideas on what the problem(s) might be and how to fix them?

Thanks,

 

Check your gas cap first, those are common codes for a loose cap.
If that checks out, are there any visable leaks?
Oh yeah, sometimes after you get the gas cap put on better the code will go off after a certain amount of mile, i threw P0455 and found my gas cap was on bad, and after I fixed it they went off after driving a bit.
That may not be it, but its worth a check.

 

I reset the SES light, drove 140 miles without the light coming on, and then this morning it came on during the initial check and stayed on. I just checked the codes and reset the light and got:

P1412
P1415
P1668

I haven't checked the gas cap yet, but will do so ASAP.

Thanks, and I would be interested in any other thoughts.

 

pop your hood. on your exhaust youll see your secondary air valves, shiny metal valves, there will be a black plastic tube comming off of each. follow this, itll go into a sheathing, and then to the intake on the pass side, a black solenoid valve, and the last stop is what you need, a black plastic cylinder that is your vacuum reservoir, one of those connections is almost deffinitly not connected right now, probably the one at the reservoir... if its not this, take it in, could be alost of other things, but gas cap isnt one of them, at least until your 455 code comes back
