how do i reset the ob2 monitors on a 2001 360

i am having trouble getting them to reset, is there a certain drive cycle that needs to be used?

 

There is a drive cycle and it has been posted a few times but it isn't clear how well it works. As I recall, the last time I saw it posted was a few months ago so you can probably find it with a search.

 

Thank you, i will take another look and see if I can find it

 

Look at post #19 in this thread:

wow, thank you very much. Im going to try it tonight

 

is it a typo to go from 2500 rpms down to 4500? or do they want you to speed baqck up to 4500 and then back down to 2000?

 

Yeah that is a bit silly isn't it? If you check Taz's attached word doc he's added a bit in there about speeding up before slowing down!

 

thank you very much

 

Fáilte! Hope it sorts the issue for you. I understand from various other member's posts that trying to achieve "readiness" state can be a very frustrating even when following those instructions to the letter.

 

yes, i just need to find a place i can drive at the rpm's for the miles they state, the 2 that are not set are the cats and the 2a (secondary air)

 

I went through all this with a customers car recently and what I learned after spending @ 20 days on it trying to do all the drive cycles and replacing all (4) o2 sensors that you have 2 options and that is either going to the referee or pull the ecus and have ferrari send them to NJ to be reprogrammed to eliminate the additional rediness indicators that will never reset... I did the latter and then it passed...

Guys,

I just got back from the 3.5 mile drive and followed taz post instructions to a T and it looks like all the monitors have reset. I can finally get it smoged!!!!! Lol. Thanks to everybody for all the help today. I will let you know after it's smoged.

 

Congratulations!

You'll have noted the response by sclja above. His is not the fist time I've read a similar comment.

Sound's like you got lucky!

Nice one.

 

If anybody does fit the excellent Interstate MTP-91, make sure you use Interstate's vent kit. The OEM vent tube does not fit. At most $5.
