Engine/Transmission (1998.5 - 2002) code p0602

[rrab1]

ok, Here is what it say's (M) ecm fueling calibration error,ecm internal fault condition detectedm What can cause this? My truck is slow to spool up if it was a gasser I would say it is loading up the carbarator and while towing it was like I could floor it and it would take for ever to kick down and get moving and it would smoke so bad that the people behind me would stop. Thanks Don

Do a search of the titles on this forum for '0602'.



My guess is your EZ is causing this code...

Over boost due to the elbow. Is a normal code when running with smarty.

I have a new stock beta stock that fixes the P0602 code, This will fix it in all cr trucks.



If you want the beta fix please send me an email request via your email since it will be a compressed file.



Thanks
