Investigating the P0100 Code on Your 2023 Dodge Challenger
A P0100 code on your 2023 Dodge Challenger — the final model year for the legendary Hemi-powered muscle car — indicates the PCM has detected a mass airflow (MAF) sensor circuit malfunction. Your Challenger is under warranty, making a dealer visit the straightforward solution.
Understanding P0100
P0100 means the MAF sensor signal is erratic, intermittent, or outside expected parameters. The Challenger's naturally aspirated V6 or V8 engines (and the supercharged Hellcat) need accurate airflow data for fuel delivery and performance management.
Common Symptoms
- Check engine light on
- Rough idle
- Reduced power
- Poor fuel economy
- Hesitation during acceleration
Top Causes Ranked by Likelihood
- MAF sensor contamination (35-40%) — Oil vapor, debris, or oiled filter residue
- Aftermarket modifications (15-20%) — Intakes and oiled filters common on performance Challengers
- Air filter issue (15-20%) — Dirty or damaged filter
- Intake duct leak (10-15%) — Cracked boot
- MAF sensor failure (10-15%) — Component defect
Warranty Coverage
Your 2023 Challenger is within Dodge's 3-year/36,000-mile warranty through 2026 and 5-year/60,000-mile powertrain warranty through 2028. Emissions warranty: 8yr/80k through 2031. Note: aftermarket modifications may affect warranty coverage if they caused the failure.
Collectibility Note
As the final Challenger model year, maintaining your vehicle with OEM parts and dealer service records may benefit long-term value. Consider having warranty work done at the dealer for proper documentation.
