There are two crankshaft sensors - one at junction of engine and transmission at bottom front of engine compartment; a second just above the crank pulley on pass side of engine compartment - both accessed from below after removing splash shields. Single camshaft sensor on front head on pass side. If you are having a crank but no start/delayed start issue - replacing the first crank sensor above fixed mine. Never threw a code and sensor ohmed out fine, but it was sending an erratic signal. BTW - if you are leaking oil around the cam sensor (another common issue), you can just replace the O ring to fix. Good luck.
