Investigating the P0100 Code on Your 2024 Hyundai Kona
A P0100 code on your 2024 Hyundai Kona indicates the ECM has detected a malfunction in the Mass Air Flow (MAF) sensor circuit. The completely redesigned 2nd-generation Kona features a 2.0L Smartstream engine on a new platform. Under full factory warranty with Hyundai's industry-leading coverage, your dealer should handle this at no cost.
The MAF System on the 2024 Kona
The redesigned 2024 Kona uses a 2.0L Smartstream MPI engine (147 hp) with an IVT (CVT). The hot-wire MAF sensor measures incoming air for fuel injection, ignition timing, and transmission management. P0100 indicates the circuit signal is outside the ECM's expected range.
Symptoms
- Check engine light on with P0100
- Hesitation during acceleration
- Rough idle
- Fuel economy below expected ratings
- IVT may behave erratically
- Possible reduced power mode
Common Causes
- Contaminated MAF sensor element (30-35%) — PCV oil vapor contamination possible even on new vehicles.
- Intake system leak (20-25%) — Loose connection or improperly seated component.
- MAF sensor or circuit defect (20-25%) — Manufacturing defect on new platform—warranty claim.
- Software calibration issue (10-15%) — New platform may need ECM updates.
- Connector or wiring fault (5-10%) — Assembly-related issues.
