Investigating the P0100 Code on Your 2022 Dodge Challenger
When your 2022 Dodge Challenger triggers a P0100 code, the PCM has detected a malfunction in the mass airflow (MAF) sensor circuit. Your Challenger's engine — V6 or Hemi V8 — 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 Challenger's naturally aspirated engines have relatively simple intake systems, making contamination and modification-related issues the primary concerns.
Common Symptoms
- Check engine light on
- Rough 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
- Aftermarket modifications (15-20%) — Cold air intakes, oiled filters
- Air filter issue (15-20%) — Dirty or damaged filter
- Intake duct leak (10-15%) — Cracked boot
- Connector or wiring fault (10-15%) — Loose connection
Diagnostic Steps
Check for aftermarket intake modifications first. Clean the MAF sensor ($10-15). Inspect the air filter and intake ducting. Use wiTECH or compatible tools for live data.
Warranty Status
Basic warranty (3yr/36k) through 2025. Powertrain (5yr/60k) through 2027. Emissions: 8yr/80k through 2030.
Estimated Repair Costs
- MAF sensor cleaning: $10-15 (DIY)
- MAF sensor replacement: $100-260 (OEM) + $80-150 (labor)
