OBD 1147 code, any idea?

Hi, my Boxter 2.5 1998 has a trouble code 1147 present.
I could find what it means. Anybody knows?
Thanks

The Porsche OBD2 Manual for your car doesn't list P1147. Are you sure that's the code?

I have a OBD II program, and that was the code (together with 0140 and 1121) which it gave.

My problem is that the is a lot of white smoke coming out, NOT after starting the engine, but rather after 5 minutes.

I thought it is the oil separator, and I changed it, but the smoke continues to come out.

Regards

Kare

P0104 isn't in the manual either. P0101,0102, and 0103 are MAF related faults, if that helps.

P1121 - Oxygen sensor heating 1 ahead of catalytic converter - below lower threshold.

If you email me I can send you more details in an attachment.

edit:
There is a list of generic codes here: http://www.troublecodes.net/OBD2/Pcodes.shtml which shows P0104 as an intermittent MAF circuit, but still doesn't list P1147

I think it is 0140 not 0104, Richard -- O2 Sensor Circuit No Activity Detected (Bank 1 Sensor 2)
