Question about 1995 Plymouth Neon
People shouldn't guess - they should say "I don't know".
As I just replaced my head gasket on my 1995 Plymouth Neon - I have the standard engine common on most makes - manuf. in U.S. it has a single overhead cam in the head.
I took the head to a machine shop to have it inspected, pressure checked, cleaned. It was easier for me to have them replace the valve stem seals as you need special tools for the valve springs - better to let an experienced person do it plus it was cheaper than buying a gasket with seals * head bolts, etc. as the machine shop obtained the parts at a much lower price - so all I had to do was buy the head gasket for under $50. The machine shop charged me about $200.
Anyway when he milled the gasket mating surface of the head he removed the camshaft position sensor (square shape with 4 bolts, black, & on inside has a blue o-ring for sealing) . The camshaft position sensor has to be removed inorder to pull out the cam shaft from the head! The upper timing belt pulley mounts on the other end of the cam shaft.
So it is on the right side of the engine while you are facing the vehicle just under the valve cover on the side of the head. Your air intake amd other lines on the right side hide it from view so they have to be removed. To replace it your battery has to be removbed and the battery holder. Remove air intake tube. Drain freon. Disconnect coolant lines into fire wall. That should give you room to replace it - unless your throttle cable has to also be removed. You will have to look an see - as you need to access the four bolts holding it into place. There is a clip on the outside of it where it plugs into computer. Do not brake clip unplugging it - open clip gently before removing it. Chilton's Manual 20600 Chrysler Neon 1995-99 Repair Manual Section 3-42 Figure 156 shows the camshaft position sensor being removed from the right side of the head (facing the engine from front of vehicle). Before installing new one be sure to clean surface gently -dry no oil film and o-ring seated properly so it will seal properly. Tighten all four bolts gently - Torque is minimal. Over tightening can crack the plastic - so tighten with minimal torque to seal it evenly between all four bolts. Lightly lubricate bolts before reinstalling. Note: a faulty sensor code may indicate that the lobes on the head have become marred, worn below erviceable limits, especially if operated with low oil level & or low oil pressure - bad oil pump. So those conditions may need checked as well. Car may need a new cam shaft, head removed new head gasket, oil pan & oil pump removed/replaced. And to do that on a Neon since you have to remove the timing belt and other belts you might as well replace timing belt & other belts at the same time. Finally while all that is off change the water pump - unless you enjoy removing the harmonic balancer, etc. just to change it later on as it is behind the timing belt cover!
Note: The camshaft has a magnet that bolts into he end of the shaft with an allen head. It is a slim possibility that the magnet for some reason is not strong enough to break a field - send a signal through the sensor as the cam shaft rotates. So once the camshaft sensor cover is removed consider replacing the magnet bolted to the camshaft also. And make sure you do not have a short in the sensor wires going from sensor to your computer as that will trigger a faulty code also!
Good luck. I hope I have been helpful as well as specific enough.

I had the same problem. Another code which was set off was my knock sensor which was causing a timing problem. It sounds like that may be whats actually wrong with your car the other sensors tend to trip as a chain reaction because of the main problem. it will make your car difficult to start and it will run crappy and accelerate very slowly. it almost feels like it doesnt want to shift although the transmission is fine. I changed mine and after it had time to reset, the check engine light turned off and it drives great again. it only took about 50 miles to reset, and the sensor cost me $35.

Its on the back of the engine. it has a 3 wire plug and its kinda hard to see. Just remember its on the back of the engine on the head....

Why are you looking for a cam sensor (cmp). You can test the sensor for any and all diagnostics up above in the harness for the 5v reference signal that allows it to operate properly. You can also check the pulse/signal in the harness as well.
It's either on the front of the head or the back, however, your model, depending on the engine, may have a camshaft synchronizer, in whch case it would appear to take the place of where a distributor would have been. I think the cam sensors on the chryslers are on the front and the crank (ckp) sensor (engine speed sensor according to Chrysler) is in the back down low by the rear of the engine.
What's the problem you're trying to solve? A crank, no start? Surging?

SOURCE: Camshaft Position Sensor
On the drivers side of the head. Should be a 2 or 4 bolt sensor, with the plug at the bottom. Not a whole lot of room to get to it, but fairly easy.

REMOVAL & INSTALLATION The camshaft position sensor is located inside the distributor. On some distributors, the camshaft position sensor is not serviceable (replacement parts may not be available separately). If the camshaft position sensor is serviceable, use the following procedure.
