Hi, driving his afternoon, the service engine light came on. My code scanner from ebay does not have Land Rover as a manufacture thus showing no description only the codes. P1412 and P1415

I have cleared the codes to wait if it comes back on again. I assume this has to deal with emissions? Would changing the mufflers caused these codes? After each drive, the truck would have a strong foul smell. I keep thinking is the welding fume or maybe the coating is breaking in.

 

They are Secondary Air Injection codes and you probably ought to let a mechanic tackle those.

 

Any chance you could elaborate on "secondary air injection" I like learning about cars lol sorry.

 

Sure, what year is your Disco?
This is an emmison device that pumps more fresh air into the exhaust to help the cats burn of the junk.

 

I went ahead and added it into my sig. 1996 Discovery I 4.0. Does that system have any other names, I remember talking about that in auto class, in highschool mind you, and I thought it had another name.

P.S. Mike this is Brian, I tried to talk to you last night twice, during the hail storm and right when you sat down to eat. I hope there isn't to much damage to your vehicle(s) or house. You can call me back whenever your done dealing with the damage and have some free time, I understand it will probably be a hetic day lol.

 

My P1412 was a hose a that came off.

 

So, I am confused, 96's didn't have secondary air.

 

I just wanted to know what they did mike, I had no idea what year model they came on. The only car I have that I work on alot (besides this one) is a 1992, so what little emissions it had have been removed. (Track only car, almost never drive it down the road).

 

So theres nothing I can inspect or change? Broken hose or vacuum tube?

But my concern is--is the muffler mod that caused the trouble codes? Had anyone else on this board experience the same codes before? How did you trouble shoot it?
