Today I got a CEL and the codes are:

P0130 Oxygen Sensor Ahead of Catalytic Converter (Cylinders 1 - 3) - Intercore Short Circuit or Limited

P0150 Oxygen Sensor Ahead of Catalytic Converter (Cylinders 4 - 6) - Intercore Short Circuit or Limited

P1313 Misfire, Cylinder 1, Emission Relevant

P1314 Misfire, Cylinder 2, Emission Relevant

P1315 Misfire, Cylinder 3, Emission Relevant

P1316 Misfire, Cylinder 4, Emission Relevant

P1318 Misfire, Cylinder 6, Emission Relevant

P1319 Misfire, Emission Relevant

My question is, will the O2 sensors throw these codes? And will changing the sensors correct the problems?

Has anything recently been changed on the car - very odd to have both banks and all cylinders with faults at one time.

The only thing that has been done is a throttle body cleaning. Last week, I got a 1124 and 1126 code and they cleared. They pop up occasionally and clear and are random. I have been waiting for a hard fail to replace the sensors. This is the first time that I have gotten these. The CEL triggered after about an hour of fairly constant speed highway driving while I was idleing at a stop light. I just got back from running some errands and the car is running fine except for a slightly high RPM on start up..about 2000 and then down to normal. Kinda baffeling...no lights...Tomorrows commute will tell I guess...

As I said it would be really unusual for two O2 sensors to go at the same time. Perhaps you should double check the connectors and wiring.

I'll go back tomorrow and double check my work from the TB cleaning ad make sure there are no air leaks. I'll update tomorrow. Hopefully, it will be something tha simple.

Threw a CEL on the way home last night and checked it this morning. Same codes as above. So, I took a look and some how one of the bolts for the TB is gone. I have taken everything apart again and I have a new bolt and a new ICV gasket ordered (it was cracked). They will be in tomorrow. I hope after I put everything back together this episode will go away.

Any one think this could be the problem thowing codes on both banks at the same time?

P0130 Oxygen Sensor Ahead of Catalytic Converter (Cylinders 1 - 3) - Intercore Short Circuit or Limited

P0150 Oxygen Sensor Ahead of Catalytic Converter (Cylinders 4 - 6) - Intercore Short Circuit or Limited

P0304 Misfire, Cylinder 4, Damaging to Catalytic Converter

P0305 Misfire, Cylinder 5, Damaging to Catalytic Converter

P0306 Misfire, Cylinder 6, Damaging to Catalytic Converter

P1313 Misfire, Cylinder 1, Emission Relevant

P1314 Misfire, Cylinder 2, Emission Relevant

P1315 Misfire, Cylinder 3, Emission Relevant

I recleaned and put every thing back together, taking time to triple check all of my work. I cleand the miniscule amount of oil residue frome the "j-tube". I ensured that all electrical connections were tight. Then I took it out for a test drive. So far, no CEL and it is ideling smoother. I had to replace the gasket for the ICV and I now have all 4 bolts in the TB. I hope that this cures the P-codes I have been throwing. I will keep ya'll posted...

Hello did you ever find out what was throwing all these codes?  My 1999 Boxster came up with the exact same code readings and I wanted to know what you did to fix it and what it was.  Hopefully you are still active on this board and will get this.  Thanks!

If you read the post from 2009 directly above yours, he tells you what he did...………………………………..

Hi I understand that but there was no follow up as to if it worked or not.
