I am sure that this is due to the NHP headers.

When I checked the motor status the catalytic was pass but the 2 fails were for the oxygen sensors and fuel tank ventilation.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1Original post

Hi everyone, I just flashed my 987 Boxster . CEL light was on last year due to the installation of NHP catless headers. The problem I have is I diagnosed the CEL with Durametrics. There were numerous codes but all that I am sure I can fix. When I checked the motor status the catalytic was pass but the 2 fails were for the oxygen sensors and fuel tank ventilation. I am sure that this is due to the NHP headers. Does anyone have any idea what could be wrong? Is it that the o2 sensors were not connected to the header when installed? The header was installed at a Porsche dealership. Thanks Miles

POST 2Original post

Are these stored codes or active codes? From discription, it sounds like they are not active anymore and you just need to clear them.

POST 3Original post

How can I tell the difference? My big problem is that I have the o2 sensor and fuel tank as a fail. Do you think it is because of the install of the header? Thanks

POST 4Original post

Simplest way to tell the difference is to clear them. If they come back, then the condition is ongoing. BTW, Durametric logs the codes, and allows you to print them out. So you don't really loose them if you are worried. When I run a scan (even with no check engine light), I get weird stuff once in a while. It was probably just a fluke that didn't repeat - so the ECU didn't display any problem with the light. Your fuel tank code may be one like that. Maybe you started the engine with the gas cap loose.

POST 5Original post

it looks like you are not looking at fault codes but readiness.

POST 6Original post

Hi Jhoffman, I was looking at the readiness as it is the basis of passing an emissions test. Thanks Miles

POST 7Original post

When are you checking readiness? Your car should be nice and warm.

POST 8Original post

Thanks Jhoffman. I tested it for readiness after 3 months of no driving. I will,check again after driving her to the dealership. I am concerned that the dealership did not install NHP headers properly. I checked the max speed motors site and found this O2 Oxygen Sensor "Check Engine Light Fix" I wonder if this will solve the problem. Do you know if anyone has not used this and haven't had a problem? Thanks Miles

POST 9Original post

If you have catless headers and dont have a flash that codes out o2 sensors than you will have a check engine light. You can try those simulators but they dont always work.

POST 10Original post

I told softronics about the catless headers. So I have cleared the codes now so I hope this works. I will update the post when I get the car back on Thursday.

POST 11Original post

Headers won't cause a fuel tank vent code. Typically it's from a vacuum leak.

POST 12Original post

Thanks diver dog. I will relay that message to the service manager. Miles

POST 13Original post

Thanks for all the advice. Passed emissions today :dance: Miles

POST 14Original post

I had the same problem, O2 sensor not ready due to softronics tune. It was solved by returning to the original tune files.

POST 15Original post

This is not caused by the Softronic flash yet changes to CA emissions changed in May of 2015. Softronic includes the original file to flash back for any reason and CA has changed standards that are outside of the federal regulations since 2000. CA and a few have decided that the only non ready status will now be the "Tank Vent" in which is their own defining of Fed law. You may contact Softronic for an update for this or simply flash to the original file we have provided in all files.

POST 16Original post

Can i disable/program/raise with durametric pro o2 sensor? I want to remove all cats.. But at the moment i don't want to flash with softronic. Thanks
