on my 2002 dakota, I was told to take out fuse 19 then turn to run not to start the truck...but i have no clue what fuse 19 is, nothing labled pcm either this is all to see if i can fix my p 0456 code that wont go away...

 

Fuse 19 is in the fuse block behind a panel on the driver side of the dash. I was told to reset the PCM all I can to do was disconnect the battery, play like your going to start the truck and then reconnect the battery.

 

too reset the pcm. disconnect the neg battery termanill, for 20 minutes. this will clear pcm. reconnect termanill, and start and stop truck 3 times. on the third time leave the truck running. let the computer learn the new peramiters that are being sent to it for about 5 minutes than take truck for a ride. should be all set. every time you put a different mod on the motor .intake, chip, injectors it is a good idea to reset pcm. if not it will take about 300 miles to learn the new peramiters

 

ok thank you worked gerat and the c/e light is not on!!
