Lost line 4, now cam sensor code
 

I sprang a leak on injector line 4 (holy crap does a lot of fuel spray out at those pressures). I got the line replaced no problem. 2 days later (today) I get a cam sensor error code. I'm thinking it is diesel getting into the connector given what I've read on the forum.

My question is, which connector is the most likely culprit? On the sensor, or on the ECM? (I'll be pulling the sensor connector tomorrow... Engine was too hot tonight). They don't really make all those connections accessable, so... hints would be great.
