P0100 on Your 2022 Chevrolet Silverado
A P0100 code on your 2022 Chevrolet Silverado means the ECM has detected a malfunction in the mass air flow (MAF) sensor circuit. Your Silverado uses the 2.7L turbo, 5.3L V8, 6.2L V8, or 3.0L Duramax diesel, all depending on accurate MAF readings for fuel control.
Symptoms
- Check engine light on
- Rough or unstable idle
- Hesitation during acceleration
- Reduced power and towing capability
- Poor fuel economy
- Possible stalling
Common Causes
- Contaminated MAF sensor (34%) — Three-plus years of dust, oil, and debris. Work truck conditions accelerate this.
- Wiring or connector issues (22%) — Heat and vibration from the engine bay.
- Faulty MAF sensor (18%) — Internal failure.
- Intake assembly leak (14%) — Loose boot or clamp. The 2.7T has turbo piping connections.
- Air filter restriction (7%) — Overdue change.
- ECM issue (5%) — Rare.
Diagnostic Steps
- MAF sensor cleaning — Remove and clean with dedicated MAF cleaner spray.
- Intake inspection — Check all post-MAF connections. On the 2.7T, inspect turbo piping.
- Air filter check — Replace if dirty.
- Connector inspection — Check for corrosion or looseness.
- Scan tool data — Read MAF values with GDS2 or compatible scanner.
- MAF replacement — If cleaning doesn't resolve the code.
Repair Costs
- MAF cleaning: $10–$15 (DIY)
- Air filter: $18–$35 (DIY)
- MAF sensor: $145–$360
- Intake boot/piping: $80–$220
- Wiring repair: $95–$280
