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.http://986forum.com/forums/uploads01...1368828464.jpg

first off all U got to scan for trouble codes to c why U have MIL
go to autozone and ask for it
then post codes here

Thanks for the tip... I called Autozone and I'm vising them tomorrow in the morning...said they will provide me all the trouble codes:)

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....

You guys use a lot of acronyms:) I'm a new bie in Porsche forum and it's challenging:)

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

Fuel Flap
 

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

alignment
 

Thanks for the info.

Scanner
 

Thanks... I've decided to go for a more inexpensive one... Actron.

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.

Porsche 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.

Fuel Flap
 

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.

Your car has 4 O2 sensors, bank 1 is the passenger side. The sensor in question is on the passenger's side nearest to the head (before the cat). Check the wiring, if it's good the sensor needs to be replaced.

Hi thom4782 thanks for being specific. Do you have any suggestion where I should buy or which brand I should buy? It seems like 02 Sensor have a wide price range between $50 to $250 starting from ebay to local stores (Autozone $ Orielly's).

The code you are seeing is not related to the locking fuel door. It is caused when the tank is venting fumes to the planet.

Access
 

Hi Paul ... and I believe I can access the 02 Sensor (Passenger side) from the floor by lifting up the car and not through the main engine (from behind the seat).

Thanks.

Awesome.
 

Thankssssss. Now my aftermarket fuel cap goes to the thrash.

You said:
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.

The door has an air bag, disconnect the battery for a few minutes before doing anything with the door.

After hooking up the battery:

enter your radio code into the radio

One at a time, roll the windows the whole way up, then release the button, then hold it down for a few seconds to program the up position.

without touching the gas pedal, turn the key until the idiot lights come on, wait a full minute, turn off for at least 20 seconds to program the off throttle position of the gas pedal.

Must be done from under the car, removing rear tire helps.

Radio Code
 

Do we have a generic RADIO CODE for every Porsche car or it's a universal code? Where do I get the code.

Thanks.

BTW it is very difficult to siphon fuel from your car, just try getting a hose down the filler tube.

Radio codes are unique, original owners are given a card with the number. Sometimes owners write it in the owners manual or the options sticker on the front hood. Or call your dealer or see one of us that have the factory computer that can read it. Its a four digit number.

Thanks
 

Thanks Paul. I'll call the dealer tomorrow and see if they would retrieve the radio code... FOR FREE...LOL:)

Only if they know you or if you can prove to their satisfaction that you own the car.

Or join Renntech and perhaps you can get it here:

Dol
 

Well if Porsche has problem with my ownership they need to deal with DOL/DMV:D

Accout Failure with RennTech
 

I tried a dozen time to join RennTech but couldn't create a new account. Bummer!

Gentlemen... so I worked with my FUEL FLAP today. I did pulled the hook on the passenger side door. Sprayed some lubricants from both sides; from the door side and the fuel flap side. The actuator is active and the lock is working flawlessly.

The only issue... which I believe that it's a poor Porsche's mechanical system; I have to lock the doors every time I want to open the fuel flap to put fuel/gas:(

Ramps To lift Boxster
 

I've order 02 Sensor today from Autozone (Bosch brand). I'm excited to replace the oxygen sensor by myself.

Is there any idea to lift the car apart from using jacks. I've come across ramps. Seems like the ramps will work to lift up the rear tires. It lift's up 8."

RhinoGear is inexpensive, light and safe:
