Dear Forum, I have a 2004 Cayenne Turbo with 87k miles on it. I purchased it used in February and encountered the P0130 code in late April. I replaced the bank 1, sensor 1 02 sensor (passenger side, in front of catalytic converter) in mid-May, cleared the code and all was well until now. The code has re-appeared after approximately 150 miles since replacement. Hs anyone experienced a similar issue of a P0130 code soon after the O2 sensor replacement? I welcome all suggestions. FYI - in an attempt to give back to this good community, I did post my replacement procedure in this forum. Some additional background: 1) vehicle was purchased with cat bypasses for both secondary cat's. 2) vehicle passed Illinois emissions before I purchased it 3) vehicle passed PPI before I purchased it 4) vehicle was purchased with an ECU tune from EP labs Thanks in advance!
Unfortunately, I am back with another problem or problems........ A couple of days ago a check engine light popped up on my 997.2s and because it is my daily driver, I was not able to immediately diagnose the issue. I went ahead and ordered a "Carsoft POR II" scanner off amazon as i thought it would help my understanding in what the problem was. (Getting to the point.....) Today while I was driving home from class, the car was running very rough. I decided to pull over and give the scanner a go... DME CODES; P0660 INTAKE PIPE SWITCHOVER FINAL STAGE P0153 02 SENSOR AHEAD OF CAT BANK 2 DYNAMISM P2099 A/F RATIO CORRECT. BEH. CAT. BANK 2 ABOVE RICH CONTROL UNIT P2198 02 SENSOR AHEAD OF CAT. BANK 2 TOO RICH SIGNAL P0174 BANK 2 TOO LEAN P0171 SYSTEM TOO LEAN P2196 02 SENSOR SIGNAL BIASED/ STUCK BANK 1 SENSOR 1 Being the person I am, I went ahead and cleared the codes dreaming my problems would magically go away. ? About 10 minutes into my commute the codes again popped up but this time, there was something a bit different....... THE NEW CODES INCLUDED; P0174 SYSTEM TOO LEAN BANK 2 P0171 SYSTEM TOO LEAN BANK 1 P0306 MISFIRE CYLINDER 6 P0305 MISFIRE CYLINDER 5 P0304 MISFIRE CYLINDER 4 P0300 MISFIRE - TOTAL ERROR P0660 INTAKE PIPE SWITCHOVER FINAL STAGE About 2 months ago I installed a new O2 sensor bank 1 sensor. While at it, I had a new AOS installed as well (OEM parts). There are some theories I have in mind but as for now, I am truly stumped on this issue. Does anyone have any experience with this madness?! Thanks for reading! ? This morning I started my car again and a puff of white smoke shot out of the tail pipes. The smoke did clear up really quick.

Hey guys, So I'm having this issue that is driving me crazy. My SAI (Secondary AIr Injection) and Oxygen Sensor are not reaching "Ready Status" A little background about my car. 2006 Boxster S 3.2L FVD Exhaust system GMS Headers with 200 cell cats - has all 4 O2 sensors attached. 996 throttle body and distribution hose ECU Tuning Group tune I had the car up in BC Canada since 2009 (although it is a US car) and had no problems passing the sniffer and obdII tests - both before and after all the mods except for the ECU tune. I went to get my emissions testing done last week in Texas and failed due to the 2 systems being in not-ready status. I figured it might have to do with the cat delete (ROW) configured in the tune. I sent my ECU back to ETG in California and had them re-flash my ECU in order to re-enable the O2 sensors. I cleared all codes and figured I would start fresh. I drove the car about 120 miles and attempted to follow the drive cycle mentioned in the forums but it was really tough with the roads out here. Everything is in ready status except for the SAI, and the O2 sensor. I can manually start the SAI using the Durametric system so I would believe the pump is not bad; however, I'm not sure that I"m hearing the SAI start up when I cold start the engine. For testing purposes I unplugged my O2 sensors from both bank1 and bank2 and they both threw fault codes which confirms that the ECU tune re-activated my sensors. I've uploaded a few pictures with the results from a OBDII app as well as the Durametric Software to my Google Drive. I'm not quite sure how to interpret the Durametric Voltage results - especially the negative 50 V and -127V - seems quite odd. https://drive.google.com/open?id=0B4ncE-o5M02DeUlLZVlxRV9hX3c Any help or guidance will be appreciated as I'm out of ideas. Thanks, Joel
I have a 98 Boxster that started showing the Check Engine Light. Check Engine Light came on and the codes for the Durametirc software were P1125 Oxygen sensing range 1 Cylinder (4-6) and P1123 Oxygen sensing range 1 Cylinder (1-3). I cleared the codes using Durametric Diagnostic Software and no check engine light appeared. The other day the check engine light came on so I decided to check the fuel pressure. I activated the fuel pump through the Durametric Software and the reading was 52 psi.Also, here is another caveat which may or may not have something to do with the Check Engine Light. When using the Durametric Software it only allows me to access the Engine Option for ME5.2.2 for 1997-1999 which is fine. However, it won't allow me to access any other options like the ABS/DSC/PSM 5.3 for 1997-2001 or the Instrument Cluster K01 for 1997-2000 and it always tells me the cable is unplugged (even though it is not and the green light is on) for the Airbag, Air Conditioning, Alarm, etc.I sent my cable back to Durametrics and they checked it and said it was something to do with my wiring. Any suggesstions about fixing the oxygen sensing issue or troubleshooting the other issue so I canuse the software?
motolz posted a topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)P1121 P0160 P1117 1999 996 I don't think there is an easy answer to this but I figure I would try before admitting defeat and taking my girl into the doctor. I recently had my CEL come on and it was throwing an MAF code along with a P0160. Since I sprayed out my MAF about a year ago, I decided to replace it, and got the above codes. I replaced my bank 2 post cat sensor, which was on the topside of the exhaust on the drivers side (pipes cross in the back)...let me tell you it was tough to get out, even with an 02 tool. But I got it and replaced it with a a Bosch O2 sensor, same number and all. Cleard the codes and still I get the same. Also, I can nearly watch my fuel gague moving, I burned about 1/3 tank on a 40 mile trip... (I know we can all do that when we try, but this time I wasn't trying, I was driving sensible!!) From all of the reading I have done, this seems to be an electrical issue. I am not very well versed in ohms, volts and amps I am afraid. Am I at the end of my DIY path on this one? Any suggestions...is it possible the new 02 sensor is bad? It was bought from Pelican. Thanks in advance for all of the help! T
