Yes, it does.

Heated Oxygen Sensors (HO2S)

OPERATION

The oxygen sensors supply the computer with a signal that indicates a rich or lean condition during engine operation. This input information assists the computer in determining the proper air/fuel ratio. A low voltage signal from one or more sensors indicates too much oxygen in the exhaust (lean condition) and, conversely, a high voltage signal indicates too little oxygen in the exhaust (rich condition). The oxygen sensors are threaded into the exhaust manifold and/or exhaust pipes on all vehicles. Heated oxygen sensors are used on all models to allow the engine to reach the closed loop faster.

A faulty oxygen sensor due to loose connections, bad grounds, high resistance in the circuit, or opens in the circuit can cause the following symptoms.

It may help a little, but do not hang too much hope on that. If the sensor were completely shot versus just degreded from being old are two different things. Try it.

I had this same problem with our 1997 Grand Voyager. Check your spark plug wires that attach to the electronic distributor. I believe you may find that one of the pins on the distributor is corroded. Use a small wire brush or some steel wool, and see if that fixes your problem.

Check the park light fuse under the dash with a 12volt test light or simply remove the fuse and check to see if its popped. If so replace it with the same amperage fuse. IF the fuse pops again once the park lights have been switched on there is a short circuit somewhere in the park light circuit and a further inspection is required. The dash lights and exterior park lights run on the same circuit. If the fuse is OK i would be looking at the park light switch itself.

Replace the blower motor resistor.

Blower motor resistors divert power or ground through resistors to control blower motor speed
When not replaced, blower will either not function or will not run at all speeds

12.5 volts isn't good enough in my opinion. Any applicable charging system trouble codes? You should be able to check codes, yourself. Also, you could have too much battery drain with the key off, if that is the case, you can pull/replace fuses one at a time. When you pull the fuse on the problem circuit, the excess drain goes away. Check the vehicle in the dark, see if any lites are on, anywhere?

My 1998 Neon is doing the same thing. There are about 20 soder points on the back of the instrument cluster circuit board that need re-sodered. There is a video on how to do this on youtube. Just type in Neon Instrument Cluster Repair.

I'm rather to do both, fluid and filter. Make sure to use the fluid ( ATF+ 4 ) recommended by Chrysler.

Personnally I would do a partial first to see how it reacted. Some of the internal seals are most likely hardened and sometimes a fluid change will blow seals. If you change my suggestion is to drive very gingerly for a while to keep fluid pressure at a minimum while old parts adjust to it. There probably is as many mechanics that would say no to a fluid change as saying it's ok, make sure whatever mechanics advice you take doesn't have a vested interest in doing the repairs if something does go wrong.

On 4-cylinder engines, the camshaft position sensor mounts to the rear of the cylinder head. The sensor also serves as a thrust plate to control end-play of the camshaft.

yes, this could very well be a transmission issue
