The P1105 code typically indicates a problem with the MAP/BARO sensor solenoid, while P1400 points to an EGR valve malfunction. These are often related to vacuum leaks or faulty components. A thorough inspection of the vacuum lines and EGR system is recommended. Expect approximately one hour of labor and part costs depending on what needs replacement.
