What year is your eldo? and, Are you sure thats the way they are displayed?

Here's what I found (keep in mind these might not be the correct definitions);

P0139 - Heated Oxygen Sensor (HO2S) Slow Response Bank 1 Sensor 2
B1340 - Air Mix Door One Movement Fault
RS0020 - ?
RS0023 - ?

Man, I wish I still had All Data...

Can anybody with the program All Data, or the manual post the real definitions, please?
