2013 ML350 - P0336 CEL
-My 2013 ML350 Bluetech 4Matic had a rough/noisy start this afternoon, and then threw a CEL.
-Engine smoothed out within a few seconds and then ran strong/smooth without issue. The vehicle ran fine for a 15min drive home. Once home, restarted it again twice without issue. CEL stayed on.
-Used the MBII ODB reader and read P0336 code. No other codes.
-Cleared CEL light with MBII tool
-Restarted a few more times without CEL and without rough start
-I've read that it could be starter going, cam shaft sensor, bad wiring, or possibly a battery issue.
Since there were several successful starts after the car ran for a while on my drive home I'm not focusing on the starter. In addition, if there was bad wiring I'd also assume a problem would persists.
Thinking now that the battery getting tired, or possibly a cam sensor starting to fail?
Question: How many cam shaft sensors are there, and were are they/it located? I've looked for schematics online without luck.
Question: Can a cam shaft sensor fault once and then be okay?
Is my logic sound? Any suggestions are welcome.

Thx a lot guys!!
When i get to the car i will follow suggestions...
I bought a reader some time ago. It is in the car so i don't even know which one it is right now as i am away from both (out of town)... the vendor of the reader said it could real the whole car -- but, it did not read the Blue Def heater failure we had!
Anyway -- point being -- which reader is best???
Thx again

When the P0336 diagnostic trouble code has been stored in the Engine Control Module (ECM), it is an indication that the “A” circuit of the crankshaft position sensor has a range/performance error
