    We have used them here in the US for years at MUCH colder temperature's than you get without ANY issues. Put on the adaptor, add external magnets such as the Filter Mag, and enjoy both better filtration and peace of mind.......

    You should be comparing the voltages for the O2 sensor ahead of the TWC to those after the TWC: The voltage curve for the senor after the TWC should be a relatively straight line, the one ahead the should be a sine wave like pulse; if the voltage curves are both sine waves, the cat is toast.............

    No. Look at the other sensor code, P0341, the code for cam position sensor #1 showing an open circuit due either to harness issues (shorts, broken wires). If the sensor has an open circuit, a harness issue or possibly the sensor itself, the DME may be seeing confusing data. I would start with the open circuit code first...........

    For future reference, RennTech discourages the sharing of materials Porsch label's as intellectual property, and forbids the sharing of such information on this website, which you had agreed not to do when you became a member. You can obtain the information you seek from legitimate sources such as Bentley.

    P0341 is the code for cam position sensor #1 showing an open circuit due either to harness issues (shorts, broken wires). P1340 if for the timing chain on the same bank being out of position. Everything else are simple misfires.

    What does the central locking/alarm/immobilizer unit under the seat look like internally, are their any signs of corrosion or water damage?

    That is correct, and not the cause of your problems...........

    Your alternator is not functioning, running you should have 14.5V DC. Pull the alternator, check the wiring connections to be sure they are tight and seated, if they are you are in the market for a voltage regulator..........
  10. JFP in PA
    I'd start with checking the alternator, is it putting out 14.5 V DC at idle? If not, I would check to make sure you properly reconnected the wiring.
  11. JFP in PA
    The sensor should be showing a millivolt AC signal with the tire turning that varies with the wheel speed.
  12. JFP in PA
    Yes, there is a rear manual release, just like the front. We see cars all the time that are stored in climate controlled, secure garages with rodent related wire damage. Time to start looking at the wire harnesses, particularly where you said it was warm or smelled like burning............

    1. Are you sure the sides harness has not be switched? 2. Have you tested the harness for continuity to be sure it isn't damaged? 3. Using a multimeter, have you tested the sides for signal generation by spinning the tire with the meter connected to the sensor?
  14. JFP in PA
    Welcom to RennTech Yes, the Tip fluid level needs to be checked from underneath and with the trans warmed up. I am always concerned about sudden onset electrical problems in these cars after they have been sitting for a while. The wiring harnesses are capable of attracting rodents that seem to love to chew on the insulation, resulting in all sorts of problems up to and including burning the car to the ground. You need to do a search for the manual front hood release cable (video here:

    The diagram I posted is a simplistic one from the Porsche factory OBD II diagnostics manual. The wire colors and pin numbering changed on different model years, but the principles were still the same: the sensor has three wires, one for power, one for signal to the DME, and one for ground. Where did you get your diagram from?
  16. JFP in PA
    Pin 53 is power, common for most sensors Pin 21 is the signal (incoming to the DME) Pin 34 is ground, common tor most sensors It concerns me that you are not seeing a 5 volt reference signal between pins 1 and 3 when back probing the sensor connector.
  17. JFP in PA
    Questionable. Lot of people have tried various "fixes" for similar damage, only to find their efforts resulted in only a temporary repair that ultimately failed again.
  18. JFP in PA
    I'd start with that new plenum installation.
  19. JFP in PA
    Disconnecting the battery will clear codes and reset some modules to their default profiles (Disconnecting the battery will still erase the "adaptive" or "learned" driving style settings, but it will not fully reset the DME to factory defaults.) but does not reboot anything in the DME, the system is purposely designed that way.
  20. JFP in PA
    Then I would say put the car back to the way it was, clear all the codes and see what happens. This is strange.........
  21. JFP in PA
    Sorry for the delay getting back to you, took a couple days off over the holiday. From the sound of it, you missed somewhere when you tried replacing the cam sensor wiring with jumpers. Are you absolutely sure you traced the correct harness wires for cam sensor #1? Did you check to see if the wires from the sensor pass thru something else (another device) on the way to the DME? Using the axiom to always go back to where you were before the problem, can you go back to the original wires or were they cut away?
  22. JFP in PA
    The EU mandates using only non metallic anti seize compounds for environmental reasons, so the compounds available there tend to act as electrical insulators, which can cause plugs to misfire. Here, anti seize compounds are metallic and therefore both electrically and thermally conductive and work fine on spark plugs. We put a small dab of a high quality anti seize compound on all spark plugs, new or old, and have never had any issues.
  23. JFP in PA
    Get the battery load tested, if you don't have the tools, take it to an auto parts store as most will test it for free. Voltage doesn't start the car, amperage does.........
  24. JFP in PA
    Probably. Three things to check: Check each wire for continuity from the sensor to the DME, check each wire for resistance, and check each wire for voltage drop. As harnesses age, the wire can develop internal resistance over the length, or even breaks which continuity would catch. Resistance may not change much, but any increase in resistance can lead to voltage drop, and as most sensor are running at low or even factional voltages, the voltage at one end is different than that at the other (voltage drop), which drives these systems nuts.

    You will need access to the wiring diagrams for your car. Either a Bentley manual or the factory wiring diagrams.
