Im having a problem with my 2000 beetle 2.0 .It tries to start but won't, my obd2 reader shows a code and says weak signal to angle sensor in throttle body. I measured the pins on my volt meter and had one with 11.95. And 2 pins with 4.85. I purchased another used throttle body with no luck.just ordered a an ancel vd500 scanner thinking the throttle Position adaption ?

The basics, are you getting spark, is the immobilizer light blinking and do you have adequate fuel pressure? Have you had any charging issues? A dead or disconnected battery; can cause the throttle body alignment setting to be lost and cause a hard or non-start issue. Please post all the trouble codes; not just the description of them. Thanks.

If your battery is reading 11.95 it will not start your car. A fully charged battery without your car running should read from 12.6-12.8. Charge your battery and try again.

If your battery won’t keep a charge then it’s either dead or your alternator is not working properly. With a multimeter you can determine all that out in about 10 minutes.

When the car is running the battery should be reading about 14.1-14.3. If it’s reading less than 13.5 or so you will need to fix the alternator.

If the battery has been disconnected for a longer period of time, or it has lost chrge, bc a faulty alternator, the ecu will forget the the throttle body position sensor. The only way you can get it to start, is to take it tot he dealership so they re-write software. It costs about $90. Or you can try to change the battery in the key fob. That may a problem as well, since it would not recognize the key, therefore, it would not e gage the fuel pump. I had these similar issues on my beetle

I had codes p1580 and p1543. I can’t find a Schrader valve on the fuel rail. It will fire and run for just a second. I can feel the pedal move on it’s own trying to keep it running. Yes the car has set for a year battery was so dead it would not hold a charge so it has a new battery now. Also I pulled the fuel pump and emptied the fuel and replaced with new and new fuel filter. I can hear the pump run. Well this is where I’m at now

We have seen wiring issues @ the throttle body be a issue (plugs, terminal ends, bad wiring harnesses); you could also clean the throttle body and run the alignment procedure with a vw scan tool like vcds by ross tech.

Check out this thread for throttle body testing and possible electrical issues:
