I just replaced my cam in my 05 R53 but forgot to release the chain tensioner so when I started it chain jumped off and sheared the cam sensor. Bought a new chain and replaced and timed by the book. Got everything buttoned back up and excited to start but now it won’t. Checked the codes and came back as a po341 cam sensor. Pulled it back apart to check again and everything looks good. I checked the new cam sensor with another by a multimeter and both were the same. What has happened?

 

Did you make sure you put the cam gear back correctly. As in backwards?

 

the arrow is pointing outward unless there’s an arrow on both sides?

 

I had it in correctly but can these scratches cause a low input for the cam sensor?

 

Well put everything back together with a different new cam sensor and nothing no start. Comes back with the same po341 cam sensor measuring range??
