DTC 337 Crank Signal Loss - ECM detects CAM pulses without crank sensor activity. Possible open, short to ground, or short to battery power on the CKP (+) signal path. Also, possible short to battery power on the CKP (-) signal path. Verify wiring, connections at CKP and ECM - repair as required. Replace CKP (crankshaft position sensor). -

Had this issue with my 2015 210 with the PCM 343. The fix was simple; the hardest part was contorting myself into the passenger side ballast compartment to access the sensor. Took 1.5 hours in total.
Here are steps I took:
1) Remove passenger side engine divider
2) Remove rearward engine divider by removing 3 screws that go into the long end. I had to remove the a bracket holding a grease zerk and the fuel/water separator.
3) Emptied the fuel water separator while I had it off
4) Contort myself into the rear of the ballast locker and locate the Cam position sensor. It's towards the bottom of the motor, tucked behind the main crank pulley; the fuel cell is directly in your line of sight.
5) Unplug the wiring harness. Attempt to start the boat and confirm the same engine code is thrown.
6) Remove one bolt holding the bracket to the motor, then firmly twist out the sensor. There was a little dab of oil on it when I pulled it out.
7) Went to O'Reillys and got part # 213-3208, which is the crank sensor on GM V8 motors of that era. The cost was $65 (half the price of nautiqueparts).
8) Plug into the motor, screwed the retaining bolt in.
9) Motor fired right up, so I cracked a beer.
I wasn't able to find much info on my DTC 337 error code, so hopefully this will help somebody out in the future.
Happy boating!Comment
