Has anyone put O2 simulators on their OBD2 NSX? I just put headers an cat replacement pipes on my 2002 NSX and did not get a check engine light until 100+ miles on it. I have the simulators from Casper Electronics and will put them on this week. I just thought I would see if anyone else has solved the problem with OBD2 cars cat removal with the check engine light.
O2 Senors and simulators
- Thread starter AJKS
- Start date
I have the Comphtech test pipes. I have the 2nd O2 sensors in test pipes like they should be. I heard that the later cars 97 and up had a bit more tight emissons spec. That means the pre 96 NSX could have the 2nd set of O2 sensors in the test pipes and would not get a check light. The 2nd set of O2 senors only do one thing, check to see if the cat has worked.
