W166 - CPS (Crankshaft Postion Sensor)
P03022 (Fault code is not found in database) and P030300 (misfiring of Cylinder 3). I have put in a new set of sparkplug swapped coil pack. The P030300 did not follow to another cylinder that I was hoping for. My next move is to replace the CPS sensor since I have around 84k miles. I have replace few of these on my old M113 motor around 80-90k miles timeframe. I only get these 2 codes only when I'm more then 1/2 on the throttle (half load). It feel like it skipping a beat then it goes into limp mode and feel like one of the cylinder is shut down (misfiring). Until I clear the code then it's back to normal. This is the same thing happen the first time I experience it on my M113 back over 14 years ago.
If anyone that done it on the M276 remind you my M276 is equipped with Bi-Turbo. Do you need to drop the catalytic converter to get access to the sensor? When I did it on the M113 motor I got access from the top (tight fit).

Aux battery was just replace couple of weeks ago or so. The main 2-3 years ago both are OEM from the dealer.
P03022 means the PCM received an unusual input signal from the distributor or crankshaft position sensor, due to their misalignment. I always see issue with a CPS between 80k-90k miles. I have seen multiples symptoms on the CPS issue. This typical symptom It's having now is identical the symptom I experienced before.
