Investigating the P0100 Code on Your 2023 Dodge Charger
A P0100 code on your 2023 Dodge Charger — the final model year for the iconic Hemi-powered sedan — signals a PCM-detected mass airflow (MAF) sensor circuit malfunction. Whether your Charger runs the 3.6L Pentastar V6, 5.7L Hemi, 6.4L Hemi, or the supercharged 6.2L Hellcat, accurate MAF data is critical for engine management.
Understanding P0100
P0100 means the MAF sensor signal is erratic, intermittent, or outside expected parameters. On naturally aspirated Charger engines, the intake is straightforward. On the supercharged Hellcat, the MAF works alongside the supercharger boost control for an even more complex management system.
Common Symptoms
- Check engine light on
- Rough idle
- Reduced power
- Poor fuel economy
- Hesitation during acceleration
- MDS issues (Hemi)
- Hellcat: possible boost irregularities
Top Causes Ranked by Likelihood
- MAF sensor contamination (35-40%) — Oil vapor and debris
- Aftermarket modifications (15-20%) — Cold air intakes, oiled filters common on performance Chargers
- Air filter issue (15-20%) — Dirty or damaged filter
- Intake duct leak (10-15%) — Cracked boot or loose clamp
- Connector or wiring fault (10-15%) — Loose connection
- MAF sensor failure (5-10%) — Component defect
