Crankshaft Position Sensor

Code: P0335
Symptoms: Lots of cranking to start. Acceleration and engine breaking are jerky and slow. Seeing jerking in tach.

I have searched and found only one other thread that mentions this code. What is "crankshaft position sensor A circuit malfunction" exactly? Most threads I found, people were showing P0339 and replaced the sensor to fix it. Is my code something other than the sensor itself? Bad connection elsewhere??

I had a bad oil leak and this fault happened and DSC and BRAKE light have also came on.

Same thing is happening to me, DSC and brake light came on but disappeared after 2 days.

Had the codes read and mechanic told me CPS malfunction.

Do you have misfire codes too ?

No, only code it is showing is P0335.

Also, do I need to get the DME and adaptions reset? Or can this just be fixed and driven?

Could be intake side camshaft sensor

Thought that was a possibility, so I replaced that part about a week and a half ago. No change in symptoms.

Maybe you have a vacuum leak somewhere.

So, after tracing wires, checking voltages, and replacing sensors, the problem persists. Hard starts, slow acceleration, bad fuel consumption, etc. OBDII still throws P0335 upon startup, even with fresh sensor. How often are these after market sensors bad? Could that be the problem?
After visiting two local indy shops today, I have reaffirmed my disdain for them. Both told me they wouldn't just read my DME and that resetting the adaptions would do nothing. And basically said I'm barking up the wrong tree....

The more research I do on my problem, the more I find of people having the same symptoms, ie hard starts, poor engine power, DSC and orange brake light...all with no explanation of a working remedy. Anyone have any other ideas?

"How often are these after market sensors bad?" Where did you buy your part? Buy sensors such as the crankshaft position sensor from the dealer only.
