An easy way to determine cylinder banks on any common engine is to find cylinder number 1, It is always in bank number one. On your Arcadia, cylinder one is in the head nearest the firewall. If you are standing on the passenger side and facing the engine. Bank one will be on the left side, bank two is on the right or nearest the radiator.
The cam sensor you are looking for would be between the 9&10 on the original picture. That said looking at the mileage and which code you have, the problem isn't the sensor, that code actually tells you the sensor is working. Instead you need to replace the timing chains in that engine.
Crank/Cam correlation is basically engineering talk for timing chain stretch. It uses the crank sensor and sensors on the cams to measure how far the crankshaft has moved in degrees when compared to how far the camshaft has moved. Then it compares that to the programmed table and will set a code if the difference is over a set amount. As the chains wear the angles change and the computer sets a code telling you there is a problem.
Now before you tear into anything there are a couple items to check first. One is to be 100% sure your engine is full of oil. The chain tensioners work off of oil pressure and low oil can let them get loose. Next would be to be sure you are using the proper oil. If it has been a while since the last oil change, do an oil and filter change with the correct oil and then see if the code is still there.
If the oil is good and clean and you still get that code, then it is more than likely that the chains are bad. VERY common on this engine unfortunately.
