Hello (Hoping on correct forum now)

We have 2007 ML350
Got check engine light...ODB reader tells me:

P0012 - "A" Camshaft Position - Timing Over-Retarded (Bank 1)

So I searched and bough Standard Motor Products PC641 Camshaft Sensor

Installed it - Was piece of cake.

Start the car and its sluggish starting and needed couple extra crank.
Check engine light comes right back on and ODB now telling me:
P0335 – Crankshaft position (CKP) sensor -circuit malfunction

Do I have wrong Camshaft sensor ?
Or do I missed some kind of callibration after installing the PC641.

Thanks

Here are the directions to replace the CKP Sensor. I strongly suggest you buy the sensor from the dealer. Standard products are well known to be substandard unless the M/B logo is stamped on it.
