Hey everyone, im hoping someone can help. My 02 f350 seems to lose power, while the engine seems to get louder. This happens towing and up hills. I have had engine scanned, and 1211 and 1617 codes come out. But check engine light comes on then turns off. I already changed ICP sensor about 3 months ago. Please help.

1211 looks like ICP sensor.
1617 looks like injector circuit / IDM


Where did you get the new ICP sensor from?


Unrelated, but check your up pipes for leaks. Can cause low power, and it's quite common on these trucks. Might as well check the intercooler boots too. I don't think it's the reason for the codes, but it might be part of the lost power.


And :ORG welcome:
