Engine power is reduced
Don't have DPF system. It's cleaning the exhaust filter with injection diesel.
Why the message "engine power is reduced "?
If it doesn’t have the DPF, it will not have diesel injection into the exhaust. If it does have the diesel injection, it has to have the DPF. Only reason it wouldn’t have, is if someone has removed it. First thing is to pull the code as to what is causing the reduced power. Then you can diagnose from there. There are several things and failures that will cause the reduced power. We also need to know what, if anything, has been done to your truck. Is it deleted or stock, etc?
