Can you still check for the same check engine error codes with the same method (grounding TEN to GND in the Diagnosis Box) with a Power FC?

 

Has no one ever tried this?

 

The only error code function the PFC does is for the injector duty cycle and knock sensor, it will flash the exhaust overheat light or the check engine on depending on which one it is, I can't remeber of the top of my head. It does this after a certain threshold, which can be set with the datalogit

The other thing it does is highlight malfuntioning sensors in the sensor check screen.

Other than that I am pretty sure that it does not do the check engine codes.
