Investigating P0100 on Your 2020 Chevrolet Camaro
A P0100 code on your 2020 Chevrolet Camaro means the ECM has detected a malfunction in the mass air flow (MAF) sensor circuit. Your 6th-generation Camaro is available with the 2.0L turbo I4, 3.6L V6, or 6.2L LT1 V8 (SS)—all performance-oriented engines where MAF accuracy is critical.
Like the Mustang, Camaros are frequently modified with aftermarket intakes and oiled filters, which are a leading cause of MAF contamination.
Symptoms
- Check engine light on
- Rough or unstable idle
- Hesitation and sluggish throttle response
- Noticeable power loss—obvious on a performance car
- Poor fuel economy
- Possible stalling
Common Causes
- Contaminated MAF sensor (37%) — Aftermarket cold air intakes with oiled filters are the #1 cause on modified Camaros. Five years of contamination on stock setups is also common.
- Wiring or connector degradation (21%) — Heat from the engine bay, especially the V8.
- Faulty MAF sensor (17%) — Internal failure.
- Intake air leak (14%) — Aftermarket modifications or aging factory boots. The 2.0T has turbo piping to consider.
- Air filter issues (7%) — Oiled filter contamination or overdue standard filter.
- ECM issue (4%) — Rare.
Diagnostic Steps
- MAF sensor cleaning — Remove and clean with MAF cleaner spray. If you have an oiled filter, this is almost certainly the cause.
- Check aftermarket intake — Inspect all connections. Consider the oiled filter as contamination source.
- Connector inspection — Check for heat damage and corrosion.
- Intake inspection — Check all post-MAF connections. On the 2.0T, inspect turbo piping.
- Scan tool data — Verify MAF readings.
- MAF replacement — If cleaning doesn't resolve it.
Repair Costs
- MAF cleaning: $10–$15 (DIY)
- Air filter: $15–$30 (DIY)
- MAF sensor (2.0T): $125–$300
- MAF sensor (V6/V8): $140–$350
- Intake boot/piping: $80–$220
- Wiring repair: $90–$275
Warranty
Your 2020 Camaro's basic warranty has expired. The federal emissions warranty covers the MAF sensor for 8 years/80,000 miles through 2028.
