Thanks JFP, I will replace the battery. Should I just reset the the codes and see what happens from there or just take it to the local indy shop for in depth trouble shooting.. If the sensor is bad can it be replaced. Would anybody know a local shop in NJ or eastern PA who can work on the pdk if its sensor.

I would test both the battery (load test) and the charging system before replacing anything.  If either is weak, replacing it should clear the code.


It may be possible that the sensor can be replaced if it is a serviceable item (not all are) but you need to know if it is a ghost code caused by the battery/charging system before doing anything else.  If the sensor is not serviceable, the PDK has to come out and be replaced, they cannot always be serviced in the field, even by a dealer.

There are some parts available now for the PDK transmissions and there are a few vendors working on them (primarily for race cars). A good source of info is a longish thread on rebuilding them found at Rennlist:
