My 2000 ford ranger (6 cyl. 3.0) has a squeeking noise when the engine is running. I removed the belt and it still squeeks. the noise is coming from the rear of the engine compartment on the passenger side. when i throttle it the noise speeds up. PLEASE HELP!
Yes, it is the camshaft positioning sensor. I just had this happen to me two months ago. Squeaked terribly. Buy from rockauto.com and I think it comes with the tool to re-ajust and put it in. It isn't too hard, just follow the directions

I was going to go with the idler pulley as well, but the engine codes threw me off. Try this.
Ohm all the injectors any that are way out of line replace. I've used a small screwdriver with a light bulb in the handle slide the tip along side the wire and check for spark on all cylinders. I've also used an ohm meter and checked the wires it normally runs appx. 1/2 scale. Take a compression test a bad lifter or valve can cause problems. Use a can of carb. cleaner and spray along the edges of the intake manifold. If the engine smooths out you have a leak at this point. Its always possible a gasket is pinched or you have a small crack. Bad injector wires also cause misfires.
The camshaft position sensor and syncro are located on the back of the engine and will sqeek. The syncronizer sits in the engine and is run by the camshaft. the camshaft position sensor sits on top of the syncro and is held down by 2 7/32" screws. If you remove the camshaft position sensor from the top of the syncro and put about 3-5 drops of motor oil in the syncro you may fix your squeek. The syncronizer shaft that goes into the engine will dry out and loose its lubrication causing a squeek/chirp.
I have done this to a few vehicles and had great success.
Hope this helps
The ABS light could be just a misaligned sensor on the wheel or even a dirty harness plug in, many times repaired by just cleaning.
You should I would check out the pulleys and belt tensioner very soon as when they began making noises they can swarm very quickly causing damage to several items.
Keith,it sounds like you may need to clean the grooved surfaces on your pulleys,you could remove the belt and use some aerosol brake cleaner and a stiff brush to remove any build-up on the pulleys.you could also try spraying the same on the pulleys while the car is running,just be sure and wear eye protection and don't get to close to any moving parts.
