SOURCE: oil pressure light at low RPM
Before you have major repair done on your car because of the "oil pressure light", review the list and see if any of these might be the source. Some of the things on this list are things you can do yourself, some only done by a mechanic (inexpensively), and others require the aid of a mechanic.
1. Check to see if you have a leak. Low oil levels can make the oil sensor light come one. Check your oil level following the manufacturers recommended procedure or use the information listed here http://autorepair.about.com/od/regularmaintenance/a/checkoil.htm. If you do not have a low oil level, but still suspect a leak, place a drip pan under the oil plug overnight. If you have a leak, you'll see signs of it there. Then take the vehicle to a trustworthy mechanic and let them trace the leak. It is possible for your engine to only leak when it is hot, so make sure you get the engine nice and warm before you put the car away for the evening and place the drip pan under your vehicle. Other signs of an oil leak are listed below as well as an "oily" exhaust that leaves it mark on your bumper or "blue smoke" as you drive/idle.
2. Check the coolant levels. If the coolant is low, the oil will heat up faster and cause a viscosity breakdown. When the oil viscosity is low (= thin oil), the oil sensor light can come on. If the coolant is low, add more. Keep in mind that an engine running hot will heat the engine oil to the point that it thins out and burns off in the cylinders. If the coolant level is fine, have the coolant (water) pump checked. If the coolant is not circulating well through the engine, you'll probably have coolant boiling over, too.
3. If you can afford to do it, change your oil to a higher or lower viscosity. Refer to your maintenance manual and your trusted mechanic. I say this because, if your oil is thinning out too much because the viscosity is too low, your "check oil" light will come on. If your engine oil is too thick, you engine will need added internal pressure to get it to circulate. At lower RPM (just like thin oil), your engine oil light will come one.
4. Have the oil pressure checked by other than an electronic means. Your trusted mechanic can place an oil gage between your oil filter and the rest of the engine or on the oil fill cap of the engine. If you are having an oil pressure problem that is seal-related, that should narrow it down. If you can't afford to do that, when you get your next oil change, replace: the oil fill cap, PCV valve, and air filter. All these contribute to the measurement of engine oil pressure by that picky little oil pressure sensor.
5. Have the oil pressure sensor checked. You may need some weird add-on to make it behave. Do a search for the following part and read and you should have a better understanding: "part # 05017800AA a terminal/wire/vent to the oil pressure switch connector". Never forget that sensor are usually engineered to report a problem well before a catastrophic failure can occur.
6. If you're driving a high-milege car, make sure you are up to date on all of the engine-specific services. For some vehicles, it is recommended that the head gaskets are replaced. If you have internal engine leaks because of it, this will solve most of those issues. Signs of this include: coolant visible in the crankshaft area (you can see this with the oil cap off), oil fouling your coolant (you can see this in the coolant reservoir), or smokey exhaust. Expect your trusted mechanic to recommend that you change your spark plugs, timing belt, and cam shaft gasket at the same time.
7. See if the oil pump needs to be replaced. A faulty oil pump can contribute to low oil pressure as it fails (but hasn't failed, yet).
8. Do all of the above BEFORE you take to recommendation to have your engine replaced.
I have a 1998 Chrysler Cirrus (I know it's not a minivan, but hear me out). I've been the single owner and have learned more about how engineering oversights or over-cautiousness can send you to the mechanic for just about everything.
Hope this helps!

If you're on the smallish side and pretty limber, you might avoid removing the rear wheel. If not, you will likely need to remove the rear wheel and put the van on jack stands securely. I would remove the underside splash shield and gain access from underneath. It looks like you will need to unscrew the plastic insert that surrounds the filler neck inside the area that is exposed when you open the fuel door. Make sure you get the vent hooked up correctly when you are done.

I recently had the same issue, but my airbag warning lights also turned on. If this is the case, it might be the clockspring. There is a recall on clocksprings for Caravans 1998 - 2000 I believe. I got it replaced for free in the dealership. Enter your VIN in this site and it will tell you if you are covered in the free replacement warranty.
Hope this helps.

yes it will swap and you have to remove it from the bottom of the van remove the screw/clips from inside the filler door and then from underneth disconect the filler tube ti tank and the vent hose to the tank i belive there is a bracket also holding the filler tube to the body with one bolt then it snakes out of the va r insalating is just reverse

OBD-II Trouble Code Technical Description
A P0020-023 code refers to the VVT (variable valve timing) or VCT (variable camshaft timing) components and the car's PCM (powertrain control module). That consists of an oil control valve (OCV), also called a solenoid valve and other components. Basically the check engine light and associated P0020-023 trouble code means that the voltage in the circuit has fallen below a set limit for a specific amount of time (varies by make/model/engine). Bank 2 is the side of the engine that doesn't contain cylinder #1.
A code P0020-023 may mean that one or more of the following has happened:
Some recommended troubleshooting and repair steps are:
