Chrysler Repair: 02 T & C: no spark, throttle position sensor, 4 digit numbers

Question
QUESTION: Roland
 I wanted to answer your question. I am getting these readings by holding the trip button in and then turn the key on and off eight times and it just starts giving these codes.

Hi David,
The 0122 is an alternative to the 0123: the first says the voltage is too low, the second that it is too high on the throttle position sensor signal wire. The 0118 and 01193 are earlier codes that I already described. The 0508 says the idle air control motor circut input is below acceptable current.
Again, I don't understand why any of these codes would cause a no spark.
On the idle air control there are two wires from that plog on the side of the throttle body:
violet/dark green goes to pin 49 and violet/light green to pin 57 of the pcm. So check those wires.
The way your codes are reading out (three digit and a decimal point) is new to me.  I hope I am interpreting them correctly. Was there any 'history' to this situation that might be relevant? I don't understand why so many sensor codes would occur at once without some sort of common cause.
By what means are you getting these codes?

ANSWER: Hi David,
You are getting then some sort of codes related to the instrument cluster not to the engine! Turn the key only, and as follows:"on-off-on-off-on and leave on" doing that in 5 seconds or less elapsed time. Then watch the odometer window to see 4-digit numbers preseced by a P.

QUESTION: I get the same results, exact same numbers or codes. Do you think my computer went bad. The one under the hood by the battery.

Answer
Hi David,
You didn't push the 'trip' button, and you still got the unusual codes? I don't know what to say as I haven't heard of the sort or numbers you are showing if you just use the ignition key and don't push any buttons on the cluster while you are turning the key. Could the trip button perhaps be stuck in the' pushed in' position? If not. then I wonder about the computer but I wouldn't go and buy one without first trying a code readout via a plug-in reader. If the vehicle is stuck in place then see if you can borrow a reader from a friend. There is a socket under the dash next to the steering column which is where you plug it.
