Swapped Plugs and Wires, got lots of codes

[OkieRover]

2003 Discovery 4.6, 81000 miles.
I swapped the plugs and wires and this is the list of codes I got today.
Is there a list on the internet anywhere?

Lets just start the list.
p1884
P1451
P0414
P1482
P0445
P0448
P0102
P1590
P0340
P1451 (again)
P0134
P0154
most of them have to do with the "pre heater" crap, which I had to remove to get to the plugs and wires.
One of these codes is the wheel sensor which I knew was bad I think it's 1590 but I can't remember exactly.

I have all the plugs back in the right places and I checked all of the hoses, and there was a bunch of them.

There is a MAF code in there.
Lots of pre heater crap
A position sensor for a cam shaft.

If you can shed any light on to any of these codes I would appreciate it.

Thanks.

oh and the web link to the list....

You didn't get these codes from changing out plugs and wires, how long has your check engine light been on?
There is not one code here for plugs or wires and what is this preheater crap you keep talking about?

I've got pictures and I'll post them up later.
Basically it's a device that takes pre heated air and helps reduce emissions by injecting it or something.
When you see the picture you'll realize its function.
There is usually a sound, loud humm, from the heater and it runs for 35 seconds or so on startup each day. It shuts off. It didn't start up at all yesterday.
I'm going to look at the fuses and see if it is popped.
The major concern I have now is all the stuff reporting shorted to ground! I didn't touch anything that would do that. The only thing dependent on ground are the coil packs, distributor stuff the plug wire go into at the back of the engine.
This is very disappointing.
I'll have more data later today when I get back under there.

Okay just got home and checked the fuses.
Under the hood. Fuse number 2, 15 amp (blue) is popped. I put a second in, and it popped.
The Owner's Manual says it is Engine management system.

So with the codes telling me about a direct short and this fuse popping.... what ever that fuse is in line with is shorted to ground most likely.

I guess I'll start looking in the Rave.

OMG!
okay the brackets for the secondary air what-cha-ma-call-its mount to the intake.
And when you accidentally get a wire mashed between the bracket and the intake it sort of shorts to ground!
So I went to the schematic. And it had the fuse going directly to the mass air flow. So I got to thinking the wires all in there didn't have their plastic protector sleeve any longer because it decentigrated. Well I wasn't watching and got one of the wire caught back there.
I cleared the codes and WA-LA! No more codes.

Thanks Disco Mike and Army for chiming in.

Don't know that I actually helped but glad you got it sorted out
