Investigating the P0100 Code on Your 2023 Kia Telluride
A P0100 code on your 2023 Kia Telluride indicates the ECM has detected a malfunction in the Mass Air Flow (MAF) sensor circuit. Your Telluride's 3.8L V6 (291 hp) depends on accurate airflow data for fuel delivery and performance. Under Kia's generous warranty, your dealer should resolve this at no cost.
The MAF System on the 2023 Telluride
The Telluride's 3.8L Lambda II GDI V6 uses a hot-wire MAF sensor to measure incoming air for fuel injection, ignition timing, and 8-speed automatic management. P0100 indicates the circuit signal is outside expected parameters.
Symptoms
- Check engine light on with P0100
- Reduced acceleration

Common Causes
- Contaminated MAF sensor element (30-35%) — GDI oil vapor deposits.
- Intake system leak (20-25%) — Loose connection or deteriorated seal.
- MAF sensor or circuit defect (20-25%) — Manufacturing defect—warranty claim.
