Where is the crankshaft position sensor located in the 2007 Camry 2.4?

The crankshaft position sensor on Your 2007 Camry 2.4 is located along the right side of Your engine block, mounted to the cylinder head nearest the intake manifold. As You're looking down at the cylinder head, You'll see the wire going from the top of the block to underneath the crankshaft. Since it can be a bit difficult to remove the crank sensor due to its long stem, You might consider paying someone to do this: Labor costs are usually around $100, with the sensor replacement part itself running about $200. Before You shell out the money for replacements, do inspect the wiring for both of the pigtails going into the sensors; critters sometimes gnaw on these, and it's much cheaper to solder these than it is to replace the sensor!
