How in the world do I tell if my engine has Advance Evaporative Loss or not? Need to order new 02 sensors and I see this option. I found some 02's at partsgeek.com for $81 Each. Has anyone used these or is this a disaster waiting to happen. I noticed Land Rover OEM sensors are $399 Each. I think that is crazy. AB sells them for $129 Each. But I do need to know if my engine is Advance Evaporative Loss or not.

 

Pre 97 is non ael post 97 is ael. Theres a vin change mid97 Atlantic British has the vin break down on there tech pages. I would be safe to say your 99 is ael

 

I have NTK 25044 in my 99 they have the corect plug and can be found under $70

Amazon.com: Online Shopping for Electronics, Apparel, Computers, Books, DVDs & more, NTK, about $50 each.

 

So NTK is alright to use. Good. The prices are alot better. Thanks.

 

You couldnt have POSSIBLY searched for that answer before you created that thread. There are like a THOUSAND threads on that same topic. Lets try and be a bit more judicious of our thread creation

 

My momma taught me that higher thread count is always better.

 

Then cdl, o2 sensor, and tdi conversion threads beat the **** out of Egyptian cotton

 

Open the hood. Look past the battery. Is the charcoal cannister round or rectangular?

Round = Non advanced

Rectangular = Advanced

1997 was a mixed year. It is not safe to assume if it's a '97 it's AES.

Phew!
