Default Multiple Engine Codes

Starting to get random codes. Some not even listed in the code list.
Now every time I start the car up I will get a different code.
I turn it off and start it back up and I get a new code.
Is this the computer or ignition switch?
By the way, I named her Christine because she has a mind of her own.

Okay...

Let see what we have.

* Awesome red 2006 PT Cruiser GT Convertible with 69K original miles.

* Throwing "all kinds" of trouble codes.

Chances are there's one thing causing the randoms codes and maybe just one of the codes you get may indicate this real cause. Since you've already read the codes and maybe wrote them down? I'd first have the battery load tested. Low voltage could do this according to numerous reports. Then I'd use my nifty $17 code reader and clear the codes. Then I'd drive the PT and see which coded pop up. I'd like stop just as soon as the check engine light comes on. Then I'd read those codes because the first codes may be the ones that tell the story. Please report back what you find.

It's not usual for a 2006 PT to do weird things. We have another thread going right now where the dash lights are going crazy.

Make sure when you do the battery load check that you have the technician handling the battery load tester to make sure they input the correct battery amps that the battery is suppose to hold. Most of the time they will leave it at 400 amps for a 4 cylinder engine.

If the battery load test checks out good then I would suggest you check the group of ground wires going to the driver's side inner fender under the hood. The wires get corroded and not make good contacts after a period of time. You will need to separate the wires to make sure its good. These wires if not making good contact will trigger lots of different codes.

Okay, I have a scan gauge that will read and clear some codes.
It is hooked up at all times.

Another thing is that when I crank it up, I pull the gear shift to manual mode and if shows 1st gear, everything is great. No codes or problems and I can drive it anywhere until I restart the car.
But if it show 3rd and I drive it, it throws the P0882 code.
If I keep turning it off, then on until it shows 1st gear, all is good.
Sometimes it will show 1st gear, then go to 3rd.
Again if I start to drive it when it shows 3rd, code P0882 pops up.
Only way to reset is to pull the battery cable.
The battery is only a few months old.
Will check negative connectors tomorrow.

Thanks for all the help.

Probably a stupid question, but have you checked all of your grounds from the battery? Especially the one on the drivers side fender behind the battery? IF so, how about checking the insulation on your battery cables for signs of corrosion. After all, the car is ten years old and if they're the original cables, they could have the dreaded green killer hiding under the first inch or two of insulation on the cable.

Checking the ground wires and battery wires now.
When I cranked it up just now, the gauges were going crazy and it was running rough, but no codes.
Think I read that it would be the ignition switch.

I would suggest checking the group of ground wires as posted in post#3.

They looked good with no corrosion. But I took them off and cleaned them really good. I also scuffed up the panel that they bolt to and reinstalled them.
Still getting same issues when I cycle the ignition.
