Red engine light on and beeping

Same thing here but no codes popped up changed actuator sensor, still red light n beeping. Any ideas

 

Get a mechanic to hook up to your trucks ecm. It should tell him what is causing the problem.

 

I took it to cat dealer they hooked up to it but no codes showed fine

 

Is there a manual way to reset it

 

You might disconnect the battery cables, wait a few minutes and then reconnect.

 

How is your oil pressure?

 

Oil pressure good oil temp bout 200. Everything checks out. That's why I'm confused

 

Are you sure that it is your engine? You mentioned in an earlier post about your air pressure. Are you certain that it is your engine light and buzzer? Does the light and buzzer go off when the air builds?

 

Good air press. N light stays on. N yes it's the red engine light.
