P0341 - Camshaft Hall Sensor Location?

Hello everyone. Today, because misfire codes/check engine light, I replaced right-side spark plugs and installed a new right-side coil pack (I believe the left side was done about 10K miles ago.) When I fired up the car, it cranked strong, but would only start after two attempts. I checked OBD codes which revealed a P0341 Camshaft Hall Sensor. This is the first time I’ve seen this code—that is, the P0341 code didn’t show prior to the misfire codes that I was getting before the new plugs and coil pack. My question is, where is the crank position sensor? I’ve been trying to find a diagram showing its location on the motor, but have had no luck. Does anyone have a photo or a good description that’ll point me in the right direction? I see an electrical connector adjacent to the oil filter; however, I’m not sure that’s it.

The link above didn't work for me, but for those who may encounter the same question, Cam position sensor highlighted at part #30 point to, I believe, the intercooler under which you'll see a connection for the Cam Position Sensor. My issue, which was on the opposite (passenger) side, was caused by a loose connection that occurred when I replaced the coil pack and spark plugs.

For those of you who are apprehensive about taking on coil packs and plugs, the job is very easy. A coil pack takes about 30 min to replace. Plugs probably take the same just because there are 12/side and one in the back can be a pain to reach. Also, if you're going to replace your coil pack, replace the plugs at the same time if not done recently and only use the correct NGK plug. Yes, they're expensive, but this is not the place to cheap it out.

In any event, after replacing the plugs, the coil pack, and testing the voltage transformer which is fine (I also purchased the one from V12CIPACK.com which moves the location to a cooler location off the motor), I still get misfires on the passent side. The car ran fine at first, but after < 100 miles, the misfire codes returned.

Does anyone have any thoughts on where to look next?
