hi. my 03 f550 with the 6.0 runs rough on cold start. it sounds like it is running on three cylinders for a few minutes. it will even do this in the summer. i have just recently gotten a code p02285, for icp sensor circuit low. it has never had codes but always ran rough. any suggestions would be appreciated.,

thanks.
Ron

 

How many miles on the truck? How long since your last oil change and fuel filter change?

When's the last time the truck was re-flashed? Do your injectors buzz before start up or after shut down.

You may just need a newer flash (inductive heating flash), or you could have injectors/FICM going out... hard to tell.

had all this done and put and icp sensor on it and it fix it

 

60,000 miles..fresh oil and filters... no buzzing before start up or after shutdown.

 

so the problems fixed?

 

not yet.. i was going to change the icp sensor until i saw where it was. now it will have to go to the dealer.

 

if im not mistaken, if the icp sensor fails i think the ecu gives out a set pressure so it will stay running, sort of a limp home mode. it should still start and run though.

 

What's an "ICP"? I'm crosstraining in Ford for a job interview on Monday.

 

Yeah, i would like to know what ICP is to. And curious of how often the trucks need to be re-flash.
