Post PIDs - Zero read vs. "No Data"

This is admittedly a newbie question, but here goes anyway. Pls tell me if this is correct:

1. PID reads NO DATA, means the car does not supply any of the needed information to support the PID and therefore you get a NO DATA reading. Correct?

2. You set up a PID on your screen and it stays on Zero. But the little green light in the dial blinks every few seconds, and it DOES NOT SAY NO DATA. This means the system has the necessary data, but the result is a ZERO read?

Does this sound correct? I thank you. RV

Thank you Ford 150Torque!!!! Appreciate your kind and thoughtful response. I really wish TorquePro had a thorough manual. I don’t understand why they never put one together. This kind of simple stuff could be explained in a manual and I wouldn’t have to go online and ask you these kind of questions. This is puzzling to me.

Thank you again. Happy and Healthy and Successful New Year!!

i would say it depends

for standard pid i would say no issue since the standard is pretty clear

for advanced pid i personnaly saw some issue (that are not supported by the obdii standard)

advance pid you mostly request an adress and decipher the response …

in the hyundai package… i had knock per cylinder working
but total knock always showing zero

so i suspect that adress was responding ..but was always zero

just to be carefull
