Camshaft sensor problem
I have a 2005 Neon that I bought back in early 2006, but very recently, it's been giving me a headache with a problem for the past few months now. What's been happening is my engine light keeps coming on and off and after scanning it a couple of times over a few weeks, it gives me the same code -P0340- Camshaft Position Sensor Bank A Circuit Malfunction. I bought a new cam sensor (a generic one) from Advance Auto Parts and had my friend install it for me, but after a few weeks of no problems, the light came back on again. When that light comes on, my driving is fine until I hit 2000-2400 RPMs causing my engine to sputter.
It seems to come on if I'm parked on an unlevel surface or if I drive up a hill. Could it be the timing of the engine? Or the timing belt? It only has about 58,000 miles on it.

P0340- Camshaft Position Sensor Bank A Circuit Malfunction
Not sure where you got the bank A stuff from?
My manual says -P0340- No Camshaft Position Sensor Signal at PCM
This could be a sensor or bad connection, check the connector for corrosion and wiring for faults.

That's exactly what it said when I scanned it with one of the scanners from Advance Auto. Maybe the codes are a little different with the older Neons? Anyway, I looked at the connector before the sensor was installed and it looked fine, no corrosion whatsoever. It could've very well been a bad connection, but I'm not too sure. My friend (he's not a pro mechanic but he still works on cars) also told me that the sensor itself looked like it might've already been used but I doubt that the store I bought it from would ever put a part back out after it's been returned.

??? All OBDII vehicles use the same codes.
Might be the wiring elsewhere. Might be the sensor. Sometimes vehicles will only accept factory parts.

it's about 2 inches by 2 inches square, located on the drivers side of the engine block, right below the valve cover. Best to remove the battery to get to the 4 bolts that hold it in... if you have A/C, you will also have to push some of the A/C tubing out of the way.
I did mine in 22 degree weather because I had to!... took me about 45 minutes, just cuz it was cold...
