04 kia optima 2.7l crankshaft position sensor

I am attempting to change the crankshaft position sensor in my 2.7L kia optima. I have located the sensor on the engine block close to the transmission just above the starter (which I just changes last week). I have small hands so I can actually feel the sensor from the top by removing the fans and the heat shield from the exhaust manifold (but can't see it). Now here is my problem I'm using a 1/4th inch drive with an extension and a 10mm socket, assuming correct size from other forums. There isn't enough clearance between the bolt and the side of the sensor to fit the socket onto the bolt.

You might have to use an open ended wrench, if it's possible.

SOURCE: need advise on removing the top mounting bolt on a starter of a 1998 ford explorer

Hi Jcetkt, Make sure the park brake is fully engaged. Chock the wheels and prepare a long extension with the correct size socket spanner, (A box wrench set onto a long extension) Slide under the vehicle and loosen it from the bottom. It may be a good idea to have a pal guiding the wrench from top side. Regards John

I have an 03 kia optima lx my car will cut off while I'm driving. Can you please tell me what the problem is. I would very much appreciate your input on this matter

this is caused by the crankshaft position sensor located behind the timing belt. this sensor cuts off the power to the spark plug so the car won't start. it happened with my kia and then everything went fine!

Where is the crank shaft sensor on a 2006 kia optima

Hi LIsa:
On 2001-2005 vehicles the crankshaft sensor is mounted on the front of the transmission case adjacent to the flywheel.

On 2006 vehicles the crankshaft position sensor is located next to the radiator hose inlet and outlet assembly.

I really hope this helps, and just keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Have a nice day and thanks for using FixYa.

Where is the crankshaft sensor located on a 2004 kia optima

I just replaced the crankshaft sensor back in November. It is a bit of work to access, but you will find it on the inner crankshaft sprocket. This is under the lower timing belt cover. It is just a black sensor that partially covers the sprocket. You will need to remove the serpentine belts and outer crankshaft sprocket to access it. At the time I needed to change it, I also happened to be changing the timing belts as well so if you need those done soon, this would be a good time to get them done.

Would a bad crank sensor cause car to loose power? I went over a speed bump and car just stopped

Actually, On 2006 vehicles the camshaft position sensor senses the TDC point of the number one cylinder, on its compression stroke. Its signal is relayed to the ECM to be used to determine the sequence of fuel injection. The Crank sensor is used to determine RPM ranges The crankshaft position sensor consists of a magnet and coil. The voltage signal from the sensor is relayed to the ECM to indicate engine rpm and the position of the crankshaft. This sensor wouldn't affect your performance but, the Cam sensor will if its damaged. To answer you question correctly, it would be the cam sensor i would check. it actually controls the injection system. if damaged, it will cause performance issues. On 2006 vehicles the crankshaft position sensor is located next to the radiator hose inlet and outlet assembly. On 2006 vehicles, the camshaft position sensor is located on top of the engine, on the engine head cover.
