i haave a kpro v3 in a prb ecu when i turn the ignition on the fan automatically comes on and it will not read the o2 sensor. Borrowed a friends kpro v1 and everything works as it should. o2 reads and fan comes on only when it reaches the set temp. So is the Ecu damaged or is it the kpro?

Ecu or Kpro damaged
Re: Ecu or Kpro damaged
Have you uploaded the same calibration to both ECU's?
Re: Ecu or Kpro damaged
Yes sir ... same exact calibration
Re: Ecu or Kpro damaged
Are you swapping the K-Pro into your ECU when testing this?
Re: Ecu or Kpro damaged
No 2 completely different ecu
Re: Ecu or Kpro damaged
You need to try swapping the K-Pros to see where the issue is.
Re: Ecu or Kpro damaged
Swapped it ... same thing happens with my ecu , fan still comes on so I’m guessing there is a problem with the ecu and not the kpro.
Can it be fixed ?

Re: Ecu or Kpro damaged
If the ECU is damaged it will have to be replaced. You may have a dealer that can do K-Pro installs near you than can take care of this for you: https://www.hondata.com/us-dealers
