Investigating the P0100 Code on Your 2024 Kia Sorento
A P0100 code on your 2024 Kia Sorento indicates the ECM has detected a malfunction in the Mass Air Flow (MAF) sensor circuit. The 4th-generation Sorento offers either a 2.5L Smartstream or 2.5L turbocharged engine, and both depend on accurate airflow data. Under full factory warranty, your Kia dealer should resolve this at no cost.
The MAF System on the 2024 Sorento
The 2024 Sorento's 2.5L Smartstream MPI (191 hp) or 2.5L Smartstream Turbo GDI (281 hp) uses a hot-wire MAF sensor upstream of the throttle body (or turbo inlet on turbo models). The ECM uses MAF data for fuel injection, ignition timing, and 8-speed automatic or 8-speed DCT management. The turbo model's intake includes intercooler piping with additional connection points.
Symptoms
- Check engine light on with P0100
- Hesitation during acceleration
- Rough idle
- Fuel economy below expected ratings
- Transmission may shift harshly
- Turbo: reduced boost response
- Reduced three-row hauling capability
Common Causes
- Contaminated MAF sensor element (30-35%) — PCV oil vapor even on new vehicles.
- Intake system leak (20-25%) — Loose connection. Turbo: intercooler piping.
- MAF sensor or circuit defect (20-25%) — Manufacturing defect—warranty claim.
- Software calibration issue (10-15%) — ECM updates may be available.
- Connector or wiring fault (5-10%) — Assembly issues.
