Hi everyone. I need some help! I have a 2012 LR4 with about 119,000 miles. I can't get the CAT monitor past incomplete. I've tried a few different drive cycles. No luck. Can someone help a brother out? Thanks!

 

Where do you live? In a lot of states that require smog testing, you are allowed 1 monitor to still be incomplete as long as there are no codes.

 

Hi Hugh, I live CA

 

Ahh yeah, you're only allowed EVAP incomplete. Have you tried a good old fashioned 1.5 hour highway cruise? Not LA highway, i mean 50+ for extended time. Do you have a GAP tool? Any codes? If you do try to read the downstream O2 sensors as a graph and post that screen shot.
