Location of crank position sensor on your 2003 hyundai accent?

Take into consideration that the left side of the car/engine is the drivers side. With that in mind, it's on the left front of the engine, slightly to the left of the exhaust manifold. The sensor is held in place with a 10mm bolt. It's almost impossible to see at first glance. You have to get eye level with the top of the radiator the look towards the engine with a flashlight. I followed the wiring harness to finally find it. I used a deepwell socket with a swivel and 2) 6" extensions to reach it. If only fingers could see because it's a "feel" to get the socket on. Once the sensor retaining bolt is removed just wiggle the sensor and it will come out. Take the clip off the wiring connector and unplug old unit. Make sure the "O" ring comes out as the new sensor comes with a new "O" ring. A tiny screwdriver works fine for that. One last thing, the "O" ring needs to go all the way up to the bottom of the sensor, not just on the shaft.
