If there are no set fault codes in the system this sis what you will get, to test the code gathering ability of the ECU and the reader. Induce a code, say unplug the TPI and start the engine and try to rev it, this should set a code to read.

What is a TPI?

TPI. Throttle position indicator, that is the sensor at the throttle body, I used that as an example as it is easily access to unplug to see if the reader will read any code.
