Help!!! My OBC Showing THIS:(
Help.... My OBC started to shows this today while I was driving. I was driving 40mph. My engine doesn't make any weird sound nor has it reduced it's power. I've tried to open and close the gas cap properly.
Am I in big trouble?
My car model is Boxster 2000 2.7L Tiptronic. Thanks for your comments
Thanks for your help.

Taj,
Search the forum for CEL or Check Engine Light. There's a post where somebody provided all the codes and Porsche's summary (not the fix).
I've been driving with mine on for a month. Replaced AOS, was good for a few days, then it came on again. Now waiting for MAF.

I just did my alignment in Les Schwab 3 days back... I hope that this has nothing to do with my OBC issue....

An alignment can not give you a check engine light (CEL)
MAF stands for mass airflow sensor and AOS for air oil separator both of which are frequent causes for CELs
Post the error codes that you got and there are many helpful folks around here who can then give you further advise.

Gentlemen,
So I visited Autozone and here are the codes:
Troubleshooting: P1115
Definition:
HO2S sensor heater circuit short to ground bank 1
Sensor 1
Explanation:
Open or short circuit condition
Probable cause:
Failed HO2S11 (Heated Oxygen sensor- Bank 1 sensor).
The other code is P0455
This is a correct. The top cover of the fuel cap magnetic lock is not functioning. It doesn't lock. I bought a new fuel cap with a key that locks the cap to secure the gas tank.
What do I do now?
Also some questions:
1. Which code reader/engine scanner/Diagnostic Tool is the best? Autozone used an Actron.
2. Can I actually disconnect the battery while I work in Boxster? There is information that I can disconnect only for 20 secs.
Please help.
Thanks.

Put your old gas cap back on, replace the failed O2 sensor, and clear the codes. None of this requires the battery to be disconnected.

It really doesn't make a difference which OBDII scanner you're using they're all the same. If you want more (Porsche specific) info you need to get a Durametric scanner

My problem is the fuel flap and not the cap. The flap does not activate.

I think there's a servo (an electric motor- right?) that locks and unlocks the fuel filler door. Maybe just sticking from sitting or there's corrosion in the contacts?
Hey TAJ, do you know about Sunset Porsche in Portland? cheapest OEM parts on the planet!!!

Gentlemen.... so according to the scanner my problem code is P1115. Which oxygen sensor do I need to replace. How many oxygen sensors are there? Do I need to replace them all?
Is it possible that the scanner might have a faulty code because my fuel flap is broken?
Thanks for your help...I'm trying to get everything right before I buy the parts.

Hi... I just surfed their website. I don't know how their Boxster parts pricing would look like.
Thanks for sharing.

I'm guessing your fuel related code is being caused by the new cap leaking air.

Bank 1 is the passenger side of the car. Sensor 1 is the O2 sensor in front of the catalytic converter.
It's best if you purchase a sensor that includes the connector. Often, sensors with splices cause faults because the spliced electrical connection is weak.

Battery Disconnect

Hi Paul... Thanks. it's good to know that I won't fiddle with the electric line while I take care of my sensors and the fuel flap.
What if I have to disconnect the battery line for another job? Right now I've got three issues with my Boxster. It's drivable without taking care of these issues however I want to fix them all:
1. Glass not dropping while opening the passenger door. After getting help from our fellow Boxster owners I'm ready to work on this. There are threads where Boxster owner are saying battery needs to disconnected while dealing with the door. i.e. the entire panel will be taken out.
Is it okay to keep the battery disconnected for hours?
2. Fuel Flap. I still need more information. I've been browsing the net but I'm still not satisfied with the information. I may end up driving without fixing he fuel flap though CEL will always remain if I don't take care of this.
I can always buy a scanner and check regularly if my CEL is indicating anything more than my fuel flap.
3. Oxygen sensors. On the process of being fulfilled with information
To take care of all these 3 issues will be a whole day job for me
Once again your help is appreciated.

Hi Paul my Fuel Flap does not work. Will it trigger a troubleshooting code? The pin that locks the fuel flap is totally out of order.
I can still go back to my Porsche Fuel cap however the OBC might be activating this code about the fuel cap.
Thanks... I'll visit Autozone with my original fuel cap and see if the code is gone.
