Help Needed Installing CPS on a 2012 E350 M276 engine
Hello:
I have a 2012 e350 m276 with 123000 miles on it. One day, it started running rough and the CEL came on. I took it to autozone to have it diagnosed and it returned with p0300, p0302 and other misfire codes.
The recommendation was to change the crankshaft position sensor.
From all the blogs that I've read, they say the cps should be on the driver side on the bell housing; but lo and behold I have looked above and below the engine and I have no idea where it is.
Does anyone have experience changing their cps? Any help will be appreciated.
Thanks

I don't think changing CKP will help solve misfire... where did you gather that info?
Misfire can involve bad timings but CKP readily stops the engine... unlikely here, right?
Look towards these in that order :
- ignition parts (plugs/boots/coils) or
- low fuel pressure (filter/HPFP) or
- lean Lambda trims (2x upstreams) or
- PCV, VVT, CPS, Tensioners...
Mercedes M276 engine failures and performance issues are non-trivial. You'll need your own scanner to help doctor this without a parts-canon.
🤞

Folks, crank position sensor failures usually result in no-start, not misfire.
Cam position sensor failures due to oil penetration result in misfire.
@mangyan open the cam position sensors and cam magnet harness connectors and look for signs of oil. Report back with the results.
