Check oil level. If empty, your clicking maybe a bad engine bearing. It pays to get consistent, timely factory recommended service.

code p0320 refers to cam shaft position (CKP) sensor/engine speed (RPM) sensor--circuit malfunction=== causes --wiring--CKP/RPM sensor ---ECM
because the engine runs ok until it is on cruise control I would be investigating the RPM sensor for a fault
The cruise control takes its control from the RPM sensor and if that circuit is interminable the the cruise control doesn't know what rpms to maintain.

low voltage can cause the type of erratic symptoms you describe.. see if the alternator is putting out 13 to 15 volts with engine running. any autoparts chain will do this for you gratis

they could b referring to the vehicle speed sensor, which senses vehicle speed for input to ur ecm and not to ur speedometer. u most likely have 2 sensors with almost same name. their located on ur trans, an some sense input shaft speed an the others sense output shaft speed..... good luck hope this clarifies it for u a little bit

he told you to take it to a transmission specialist because that is where those sensors are located. The speed sensor is located in the transmission. It reads the speed by counting the number of teeth on a relucter wheel. (thats the simple explanation).
I sounds to me like there might be some debri in the transmission that could be affecting the reading.
The engine computer uses that information to control the engine and transmission. Without that information the transmission could go into limp home mode and or have erratic shiffting plus other problems.
I would really suggest you get it in for a test and evaluation asap. I do not consider this vehicle to be reliable or safe because the transmission could lockup and or otherwise fail.
As a side note, these minivans are notorious for having failing transmissions and most transmission shops find that the majority of their work is on this minivans. One of the reasons I have just kept my full size van.

Sounds like a faulty body control module, or the forward control module. Possibly the cluster is going bad. Is it still under warranty? Take it to the dealer, which you may have to do anyway.

Sounds like your sending unit sensor - if it was your pump going out, your engine would be history by now. Rule of thumb, if your oil check light ever comes on, it's usually too late to remedy the problem. You have a major issue, but since you've obviousely drove it quite a bit since then and it still hasn't seized up, I'm guessing you're ok...for now. Since you took it to a shop and they said you're ok, I'm assuming they checked your level and visually checked for leaks and found nothing. Either, you've got somethijng partially blocking your pick-up tube for the pump which is in your oil pan, or a electrical issue with the sensor. I would start by having someone check the sensor out and go from there...good luck.
