    I thought I would post this because I didn't find anything related to it on this forum. After changing my spark plugs I had a check engine light and a trac light on. After scanning it with my Mac tool scanner p0393 code comes up. Camshaft position sensor b bank 2. Driver's side in between the first and second cylinder closest to the radiator. I changed the sensor and tried to clear the code but it popped right back up. After further inspection the solid green wire had become loose. I was able to push it back in and put gorilla glue on the back housing and all is good. I hope this helps others

    Shoving the wire back in the hole with glue is not an acceptable repair. You need to remove the old contact from the plug, crimp on a new contact on the green wire and reinsert into the plug. This will require getting a new contact and a proper crimping tool.

    Correct (slopemaster) this was just a quick fix. AutoZone or any parts company has the plug with wires. It's a thing now, like it's a regular occurrence. It's on order and I will install it when it arrives. Until then I'm running with no codes and a healthy engine.
