What Does P0100 Mean on Your 2024 Honda CR-V?
A P0100 code on your 2024 Honda CR-V indicates the ECM has detected a malfunction in the mass air flow (MAF) sensor circuit. On a new CR-V, this is uncommon and most likely points to a factory defect, loose connection, or contamination introduced during assembly or early service.
The 6th-generation CR-V (2023+) is available with a 1.5L turbocharged engine or a 2.0L hybrid powertrain. Both use precise airflow measurement for engine management and emissions control.
Symptoms
- Check engine light on
- Rough or unstable idle
- Hesitation during acceleration
- Reduced engine power
- Poor fuel economy
- Possible stalling
Likely Causes on a New CR-V
- MAF sensor connector issue (30%) — A factory connection not fully seated or vibrated loose.
- Contaminated MAF sensor (25%) — Oil or debris from manufacturing, PDI, or an early service. An aftermarket oiled filter installed at purchase is another source.
- Faulty MAF sensor (20%) — Factory-defective sensor.
- Software calibration (12%) — ECM may need a software update to refine sensor thresholds.
- Intake assembly issue (8%) — Loose clamp or improperly seated boot from the factory.
- Wiring defect (5%) — Manufacturing wiring issue.
