Looking for Known Good CMP - CKP - 2017 MBZ
I'm sure the timing marks are off with these codes, long crank, and rattle on start-up, but want to gain experience - check using the scope, Thank you in advance!
This is the only one I could find in my files. Hope it helps.
Be careful with the camshaft trigger wheel, I had one that moved. i kept getting a correlation code.
We also had a 17 Metris at a sister store that had a shifted reluctor Nathan. More and more common on many makes anymore it seems.
I have also had the reluctor wheel shift on the camshaft before. I have seen it in metros vans as well as a GLC before which is the same engine as this C class.
2013 Mercedes B250 2.0 The first capture is known good. The second capture has a P0016 and a cam reluctor had turned on the cam.
So for y'all that have run across the shifted reluctors , is there a way to determine whether the issue is base cam timing versus a shifted reluctor without disassembly ?
Yes, just need a known good in cylinder waveform to check valve timing against the vehicle in question. This applies to any make. Or if the reluctor has shifted so far that its out like say 100 degrees on your cam/crank waveform but the car still runs okay then common sense/logic would tell you the mechanical timing is okay.
Thank you all for the waveforms and additional tips. I have also had a 6cyl. MB with a reluctor slipped, setting a P0016 or P0011. I’ll be inspecting everything on this one once it’s apart. I just haven’t had much experience/ success getting a known good for comparison. I’ve also never done a chain on the MB 2.0L yet. So, thank you all again. I’ll try to save some data (very clunky with my…
FWIW, our Dealer stocked the camshaft…Requires special tools to do job… William, to reply to your question, it's been a while since I did one, but I do seem to remember if you set to TDC and remove the cam sensors (easy) you can look down the hole and see if they're off. HTH
