I am trying to locate a resource for a list of the ECM codes in which you
can pull up on this vehicle after On Board Dignostics are run.
The system here is a OBD I On Board, I believe.
After depressing the OFF -WARMER buttons (Climate Control panel) , Diagnostics Run.
Then you depress OUTSIDE TEMP button and you enter Monitor or Sensor reading mode. Depressing HI / LO Fan buttons increment / decrement the Pointer from E020 thru E031, then the corresponding VALUE is displayed of these sensors. E020 - E031 : I am interested in obtaining a list of what each is actually reading (monitoring).

Thanks for any help !
