Investigating the P0100 Code on Your 2022 Dodge Charger
When your 2022 Dodge Charger triggers a P0100 code, the PCM has detected a malfunction in the mass airflow (MAF) sensor circuit. Your Charger — whether V6 or Hemi V8 powered — needs reliable MAF data for fuel delivery and engine management.
What P0100 Means
P0100 indicates erratic, intermittent, or out-of-range MAF sensor signals. The Charger's naturally aspirated engines use a straightforward intake system where contamination is the leading cause of MAF issues.
Common Symptoms
- Check engine light on
- Rough or hunting idle
- Reduced power
- Poor fuel economy
- Hesitation during acceleration
- MDS issues (Hemi)
Top Causes Ranked by Likelihood
- MAF sensor contamination (35-40%) — Oil vapor and debris on the sensing element
- Air filter issue (20-25%) — Dirty or improperly installed filter
- Intake duct leak (15-20%) — Cracked boot or loose clamp
- Connector or wiring fault (10-15%) — Corroded or loose connection
- MAF sensor failure (10-15%) — Internal degradation
Diagnostic Steps
Inspect air filter and MAF connector. Clean the MAF with dedicated cleaner ($10-15). Check intake ducting for cracks. If modified with aftermarket intake, check for oiled filter contamination. Use wiTECH or compatible tools for live data.
Warranty Status
Your 2022 Charger's basic warranty (3yr/36k) runs through 2025. Powertrain warranty (5yr/60k) through 2027. Emissions warranty: 8yr/80k through 2030.
Estimated Repair Costs
- MAF sensor cleaning: $10-15 (DIY)
- MAF sensor replacement: $100-260 (OEM) + $80-150 (labor)
