Bought the ML new in 2000

CEL came on at 50050 miles, dealer read the OBDII code that indicated the MAS was out of range. They reset it and said it may or may not fix it, it did not.

So I found a new MAS on Ebay motors for $165.00.

Just search Ebay motors and Nass Air Sensors and you should find some. Make sure it's the right part number!

Dealer wants $465,00 installed. Hope it fixes it.

Someone in this news group had 2 of them for sale. $100 each
