Where is the camshaft position sensor located on a 1999 chevrolet blazer? Is it visible from the top of the engine or under something?

In this wonderful vehicle, its under your distributor rotor. I suppose it could be worse, seems like nothing in these blazers is easy to get to! I've considered blowing mine up on more than 1I occasion. That's a part that rarely fails on these blazers though. What do you have going in?

I am trying to make it through inspection, but I have a code (P1345 - manufacture specific code) that I looked up online. It said that it could be 1 of 3 things: 1 - crankshaft position sensor (already replaced), 2 - loose camshaft position sensor or 3 - bad timing chain; getting ready to break. So I'm doing a process of elimination. What do you recommend.

Was the service engine light reset after you did the crank sensor? Generally these things don't reset. I would go for the cam sensor next, because the timing is no less than a huge pain in the butt. If you have an Autozone near you, they will shut that light off, free of charge, unless you live in California.

Thanks. That was my next step. Hopefully that will do the trick. I appreciate your help.
