Camshaft sensor check engine light

[Shehadehd]

Well, I swapped the two camshaft sensors and replaced the bad idler pulley on the car last weekend. My car still hasn't finished its readiness tests since the last code clear, but no CELs so far.

After removing the old idler pulley, it's evident it was bad. When I shake the pulley, It sounds like a bag of marbles comin from inside the bearing, I can't wait to open it up and see what the bearing internals look like.

I'm not sure if the sensor failure was a hiccup, or if a connection had gone bad, but unplugging it reconnecting it seems to have helped? I'm still keeping a watchful eye on the situation to see what happens.

Oh yeah, I pulled out the filter and ripped it apart like a madman. I ran a magnet over it but got no ferrous metal at all... I'm still planning on doing the retrofit, but my car is a 2000 year and the door jam says it was manufactured in January. Does that mean it's a duel row or single row bearing?
