Drive Cycle for Emission test help

45110 Views 16 Replies 6 Participants Last post by  Noodles
So I replaced the MAF on the 01 ML430, and have to get ready for the Smog test here in Ca.
Running it through the code reader, in the I/M readiness, 3 are still not ready yet: EVAP, Sec Air and EGR Sys. If more than one is not ready it wont pass. This is my second week driving it to work and back, its 16+ Mile commute and 20-60min drive.
Can anyone provide any advice on having the EVAP, Sec Air and EGR Sys sensors set?

Assuming there are no codes you can start at:

5. EGR System.....
do you have the drive cycle directions for a 2001 ML320? It has been over a month of driving and the O2 sensor monitor and catalyst monitor still are not set and tags expired in Dec 2010.
