Default Cam Position Sensor

On my 2002 C5 corvette I have now in the last few days had to reset and clear a P0343 code that appeared in the last few days. I have read extensively for the last few days about the causes of why this happens. After the check engine light appears the cars runs a bit funny but not to terribly bad but it acts really difficult to start but it does start. Does anyone here have any experience with changing the Cam Positioning Sensor which is the sensor that is triggering this code. I would like to see some pictures and a video of where sensor is and how to access it. If I am to replace this sensor is after market one type suitable or should I get the original part? Any help/advice will be appreciated.

To replace the cam sensor you have to remove the intake manifold. There's lots of videos on YouTube on how to change it out. When I changed mine out I used the OEM one and it works fine. It's a good time to change the intake gaskets and do the the oil pressure sender extension.

For ANY sensor in the car stick with an OEM part..always a good idea to check the wiring before replacing !!

I am finding on youtube a lot of conflicting videos and responses of the procedure to remove the intake manifold some say that you just have to move it forward a bit and others are saying that you must drain the radiator and disconnect the fuel line. I can do a lot under the hood and have such as water pump radiator and the such. I am a bit intimidated at trying this

I put off doing my oil pressure sensor because it looked like a big job. it was not very hard. If you have done a water pump you should be able to do this job. You just have to take your time and don't rush it. To avoid having to drain the radiator all you have to do is remove air bridge, disconnect the electrical connector, unbolt the throttle body and move it forward out of the way. The fuel line comes off very easy you just have to follow the precautions for depressurization of the fuel system. I found that taking off and torquing the rear bolts on the intake manifold are the biggest pain There are some how to's on this website that are pretty good.

Absolutely no reason to drain the radiator. No coolant in intake. I'd disconnect the fuel line, and pull the thing completely outta my way. May need to unplug coil packs, too, but cant remember. Monte is right, great time for an oil sender relocation kit. IMPORTANT!!!! BEFORE pulling the intake, spray some water (garden hose pressure only-NOT pressure washer pressure!!) all around the edges of the intake. Then maybe blow excess water off with low pressure air, maybe 35-50lbs/Sq.". This will reduce the likelihood of dirt and junk from falling into an intake port, which the piston, rings, and cylinder wont like one bit!!!.....

No coolant in the intake but the throttle body is heated with a coolant line. Some internet instructions tell you to disconnect that coolant line so you may lose some coolant if you disconnect it. Some instructions tell you to remove the fuel rails which you don't have to do.
