Engine Code P3447 on 2006 Chrysler 300 Hemi: Meaning and Repair Cost
I'm new to diagnosing engine light codes, but I've learned how to read them. My vehicle shows a code P3447, which translates to 'Cylinder 16 Exhaust Valve Control Circuit Low'. Can anyone explain what this means in simple terms and provide an estimate of the repair cost? Any insights would be greatly appreciated!
What year is your vehicle? That information helps narrow down the diagnosis. P344x codes generally indicate a transition issue between 8 and 4-cylinder operation, where the Powertrain Control Module (PCM) detects a problem with the solenoid control circuit. The repair could involve either wiring issues or a faulty solenoid — both of which can vary in cost depending on labor and parts.
