  1. 1 - Permanent magnet 2 - Sensor housing 3 - Engine case 4 - Soft iron core 5 - Inductor coil 6 - Reference mark Could be the sensor connection, bad sensor, magnet has fallen out of the flywheel or even a bad DME (but not likely). Test the sensor as follows: Remove connector. Connect ohmmeter to sensor connector, pins 1 and 2. Display at 20 °C: 0.8 - 1.0 k ohms Connect ohmmeter to sensor connector, pins 1 and 3. Display: 00 infinite ohms Voltage output at the sensor should be 0 and 7V or so at DME terminal 20.
  2. The CPS is a simple Hall effect sensor that generates a low AC voltage signal when ferrous metal passes by the sensor head. You can test the sensor still in place by using a digital multimeter set on low AC voltage, then spin the motor over to read the signal strength which should be consistent pulses. You can do the same thing with a scope.
  3. Long before I would replace the sensor, I would be running diagnostics to see if it is working or not.
  4. Check your crank position sensor; if the DME does not see the engine turning over (CPS), it shuts off the fuel supply.
  5. When you spin the engine over and the car doesn't start, what is the tachometer doing, is it bouncing or not moving?
  6. In the relay panel above the fuse panel.
  7. I would try an LED compatible replacement flasher and see what happens.
  8. Do not double post, it is against the forum rules you agreed to when you joined.
  9. Nothing.
  10. Whirring. You need to check for fuel pressure and delivery rates; otherwise, you are groping in the dark..................
  11. This photo shows the relay panel under the driver's side foot well. The fuel pump is not normally turned on unless the engine is running, but you can remove the relay and bypass it using a simple jumper wire as shown here. Remove the fuel pump relay (shown in the inset) and then jumper pins 30 and 87 (typically labeled 3 and 5 on the relay panel). This will cause the fuel pump to turn on automatically when you turn the key in the ignition.
  12. Techron works with working systems, systems with old fuel problems won't be helped at all. If you do not have the testing equipment, you may be able to rent or borrow it from an auto parts store. If you are uncomfortable running the tests, find someone in your area that is and can help you. A good starting point would be to contact your local Porsche Club of America chapter and see who they recommend.
  13. What currently passes for gasoline these days deteriorates fairly quickly if not stabilized with an additive. That un-stabilized fuel can gum up injectors and just about everything else in the fuel system if it is allowed to sit for too long. Probably your best plan of action is to see if the fuel system is functional; to do that, you need to check both the fuel pressure and delivery rate using the test port on the fuel rail and an appropriate fuel pressure test rig.
  14. P1673, according to the factory OBD II diagnostic manual for your car, it a cooling fan fault at the front of the car, not the purge fan, which is P1671. If you have the Durametric system, you should be able to trigger the front fans to run and both speeds from the Durametric, might be worth checking to make sure they are both working. I would also consider getting a "second opinion" scan with another system as the Durametric indication may have the code description wrong.
  15. Just realized something while looking for resistance values: P1673 is the code for an engine cooling fan, not the engine compartment purge fan; are you sure about that P code value? The code for the purge fan should be P1671........
  16. I do not, but perhaps another board member can chime in that has done this.
  17. P1673 is thrown because the fan is not there (open circuit), you would need to find the internal resistance of a working fan and install a resistor of that rating and install that instead of the fan. The relay(s) will also need to be in place as well. An easier "out" would be to put the fan back in.
  18. I'd check the brake rotors for run out, you may have one or more that is slightly out.
  19. I would try running it in the driveway for a few min to see what happens; if nothing goes wrong, you should be able to drive the car a few miles gently to the shop.
  20. Four functions of the coolant warning light: 1. Engine coolant level too low — light flashes slowly (0.5 Hz) 2. Engine compartment temperature too high — light flashes slowly (0.5 Hz) (engine compartment blower might be faulty) 3. Engine coolant temperature too high — light is lit; pointer on the right 4. Temperature sensor at water outlet faulty — light flashes rapidly (1 Hz); pointer on the right Note The temperature warning in point three is indicated if the conditions "engine coolant temperature too high" and "engine coolant level too low" are present simultaneously (1Hz = 1 flash per second. 0.5Hz = 2 seconds per flash) __________________
  21. Try posting in the correct forum section and you will get the answer: Lost Radio Code - post your request here
  22. You can lease a PIWIS for around $20,000 first year and get full access to it, and Porsche was offering a subscription service called PIWIS TSI where you can license access to the information system only without leasing the PIWIS system as well. Bentley was never available electronically, only as a book.
  23. Welcome to RennTech The beauty of the Porsche sports exhaust system is that if you leave the vacuum connections disconnected, it is in the loud position at all times, giving you max flow. I would simply remove the wire the previous owner installed which decreases both sound and performance and enjoy the ride.............and the sound.
