My sundannce is putting out a 3 5 5 code what does it mean?

Question edited for clarity.
Question moved to model category.

The P0606 fault code means that there's an error with your power control module (PCM). Your PCM is the computer inside your car that monitors all the vital systems. Basically, it's the brain of your car. Every time you start the car, the PCM runs a series of checks to make sure everything is okay.

What the P0303 code means. The P0303 DTC is set when the ECU detects multiple misfires from cylinder 3. Misfires cause the ECU to set the Check Engine Light and put the vehicle into a failsafe mode to prevent damage. The Check Engine Light will remain until the code is repaired.

P0303 OBD-II Trouble Code: Cylinder 3 Misfire Detected

It means you need to replace the CD player.

that is the PCM, you are scanning,,, you never said .
it means the perminante memory in the controller is scrambled.
is this a 2004 libertry or a 1995 GC?
the 2004 the trans brain is inside the PCM now.
so what is 12? that is olden days codes, not 2004....
tell the full story,, (symptoms) so i wipped out my OBD2 scan tool
jacked in to the PCM and ......???????
that?
if you get checksome errors)
1: low battery voltage, parked key off is 12.6v, if not charging issues.
2: PCM bad, pull battery cable, minus, wait 5 min, then put back.
the memory can read corrupted for 3 reasons
1: low battery
2: memory is bad. (vast reasons inside)
3: PCM is bad.

Code 303 means cylinder number 3 is not producing power. If the spark is good on that cylinder, you could have a problem with the injector or something mechanical.

1-2-2 means the sensor in the air inlet duct is disconnected or open.
2-3-1 and 2-3-2 means your o2 sensor has probably failed or possibly is related to the first. If the air sensor fails on a Regina system (square ignition coil on driver's side) then the system, being as dumb as it is, will attempt to put a constant integer in there, computing solely on MAP readings and probably guessing poorly on what the A/F mixture should be. So fix the air sensor first, reset the system, either by disconnecting the battery negative cable and waiting 10 minutes or clearing the codes out by hand.

The P0102 means Mass or Volume Air Flow Circuit Low Input
The P0101 means Mass or Volume Air Flow Circuit Range/Performance Problem
The P0300 means Random/Multiple Cylinder Misfire Detected
The P0171 means System too Lean (Bank 1)

A code 82 error means that you may need to go for an oil change. However, if you want to reset this error, do the following:
1. Put the ignition to ON position to get all electronics to work, but the car does not crank up
2. The code 82 will flash, but you should wait till the display shows the mileage
3. Toggle across to where it says oil
4. Now put your foot on the break, and press and hold the trip button, and you will hear an alert.
5. Switch off the car, and then turn it back on-the error should have gone away.

Possible causes
1) open or shorted to ground
2) poor electrical connection
3) fuse
4) bad sensor
5) Engine Control Module maybe bad

Hope this helps Tim
