possible, but would have to be an extended period in my estimation. grant - Wednesday, 18 May, 2011, at 4:22:40 pm |

Supply the error code. My WAG is it will be P0430 (or maybe P0420)... MarcW - Wednesday, 18 May, 2011, at 7:28:37 pm |

okay so i just went through replacing the oil separator and maf sensor to solve a bunch of running and smoking issues, but now ( after about 200 miles) i have another check engine light for the cat. The car runs great still, but does anyone have any suggestions on replacing this part and what it will cost ( auto zone couldnt even order it) I was thinking of getting a bypass but could that make me lose back pressure?

Mine are going bad... Watched it on the Porsche computer. Bruce In Philly (2000 S Boxster, now '09 C2S) - Sunday, 22 May, 2011, at 3:53:58 pm |
The way I understand it is the engine controller monitors the #2 sensor voltages.... MarcW - Sunday, 22 May, 2011, at 5:42:53 pm |

First, I did not understand what I saw so if anyone can fill in the blanks, please post.
My tech showed me some sort of output graph on the Porsche computer and what I saw was a sine wave in real time. The computer was attached to my running 2000S. The tech said that this sine wave was a failing cat but not to do anything until the check engine light came on. He said that a healthy cat would produce a straight line. At the time, the cat had about 150K miles on it.
Any ideas what I was looking at?
By the way, can't you get a used cat from a dismantler such as Parts Heaven? Gotta be a market for them when a low mileage Porsche meets a tree.
