Service engine soon light illuminates at start but will not pass emissions because it doesn't come on with problems. Emissions says faulty check engine light. I have 2000 disco 2

 

Have you had the codes read and then cleared? Either doing it yourself or having the guys at your local Napa/Autozone/AdvanceAuto doing it for you?

If there are truly no codes behind it all then that might clear up the SES light for you.

 

I've not had them cleared. I will do that. Also the wire is broke above my transfer case box and from a different post it may have something to Do with it

 

It might (and also might not), we would need to know what the wire was...

I'd go have the codes read, write them down, and then have them cleared. Report back here with the codes and we can help. Also, if there are any codes, they might stay gone long enough to pass emissions and then you can deal with whatever is wrong.

 

oh..ok. Well my maf code is on. So I'm going to replace that. I just did all 4 o2 sensors which cleared 4 if my codes. I have 2 left. The mag and the one that is a ghost but. Also they say my service engine light is malfunctioned. So I have one? Or just service engine soon

 

I ment maf

 

just took it to oreillys the code reading is p0102

 

Cleaning or replacing your MAF should take care of that code. Never heard of a code for a bad SES light. Hopefully taking care of the last code you have (p0102) would clear up your system and allow you to pass your emissions test.
