Newbie needs advice on OBD II codes
I recently acquired a 2001 Discovery II SE with 71,000 miles. It came from LA to Minnesota via truck. I have had it less than 48 hours and the service engine light came on and is amber. I plugged in the code reader and got the following:
0171
0174
0004
1100
It sounds like the first two are oxygen sensor issues. Any thoughts on the others? Any guesses on where to start to fix it? Could it have anything to do with the cold damp weather?

Ed,
I don't know what plugs and wires are in the truck. I have had it for 48 hours so I haven't had a chance to break into it. I did find another source that said it was probably the MAF and it could be due to a dirty air filter or simply a dirty MAF. It recommended cleaning it with electronics cleaner and putting it back in. Has anybody tried that?
Leadfoot, I have the RAVE CD. Any thoughts on how to use it with the codes? I found the page on replacing the MAF.

i suggest you do the 60k service to you truck found in the HOW TO section. if it is still throwing error codes i'm gonna say its your MAF sensor. you can't clean it, its super sensitive doesnt work. replace it with the Bosch MAF in the Land Rover box NOT an aftermarket one or a Bosch not in an LR box.

no just clear the codes and you should be OK i wouldnt let it go too long though. the computer will adjust the engine according to the O2 readings when its really the fault of the air intake. here is the part http://www.roverparts.com/Parts/ERR7171G.cfm

By the way, how is the truck running right now?

Mike,
Thanks for joining in.
To answer your question, the truck is running fine. It idles good, accelerates good, no knocking, etc. The only thing to suggest that something is wrong is the service light.
I found through a Google search that the 0004 code means fuel volume regulator circuit high and the 1100 means MAF intermittent. Who knows if the source is legit.
I checked the air filter yesterday and it looked pretty clean. Maybe I should change it anyway. Is there a thread or "How to" that shows how to check for vacuum leaks? I have the RAVE CD but am still getting used to navigating through it.
Thanks,
Greg
