LN Engineering Spin On Adaptor Decision
JFP in PA replied to Spartan1-6's topic in 987-1 Series (Boxster, Boxster S)
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.......- 1 reply

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?

Serial number decode

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..........

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.

ABS Sensor problem
JFP in PA replied to SwedePete's topic in 9PA, 9PA1 (Cayenne, Cayenne S, Cayenne Turbo, Cayenne Turbo S)
The sensor should be showing a millivolt AC signal with the tire turning that varies with the wheel speed. -
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............

ABS Sensor problem
JFP in PA replied to SwedePete's topic in 9PA, 9PA1 (Cayenne, Cayenne S, Cayenne Turbo, Cayenne Turbo S)
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? -
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:

08 Boxster P00010 code.
JFP in PA replied to vza's topic in 987-1 Boxster Convertible Top Issues and Solutions
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?
