Investigating the P0101 Code on Your 2022 Honda Accord
The P0101 code on your 2022 Honda Accord indicates the MAF sensor is reading outside expected performance parameters in the 1.5L turbocharged (or 2.0T, depending on trim) engine. The sensor circuit functions, but the readings don't match the ECM's expectations based on throttle position, RPM, and load data.
2022 Accord Context
The 10th-generation 2022 Accord primarily uses the 1.5T engine (most trims) or the 2.0T (Sport 2.0T and Touring). Both are turbocharged, adding charge piping as a diagnostic consideration. At this age, both contamination and connector issues are realistic causes. The warranty may still be active.
Prime Suspects in This Investigation
- Contaminated MAF sensor element (35%) — Oil film and dust accumulation causing readings to drift outside the expected range.
- Intake or charge piping air leak (25%) — Unmetered air bypassing the MAF sensor creates the range/performance mismatch the ECM detects.
- MAF sensor connector issue (18%) — Partially corroded or loose connector causing intermittent signal variation.
- Dirty air filter (12%) — Excessive restriction reducing airflow below expected range.
- Failed MAF sensor (10%) — Calibration drift or element degradation.
Diagnostic Steps
- Connect Honda HDS or a quality OBD-II scanner and confirm P0101.
- Compare MAF vs MAP sensor data for discrepancies indicating a leak.
- Check air filter condition.
- Inspect intake ducting and charge piping for air leaks.
- Remove and clean the MAF sensor element.
Repair Costs and Options
The 2022 Accord may still be under Honda's 3-year/36,000-mile warranty. It falls within the 5-year/60,000-mile powertrain warranty and federal emissions warranty (8 years/80,000 miles).
- MAF sensor cleaning: $10–$15 (DIY)
- Air filter: $15–$30 (DIY)
- MAF sensor replacement: $90–$220 OEM, $160–$340 installed
- Intake duct repair: $25–$90 parts, $70–$180 installed
DIY Feasibility
The Accord is DIY-friendly with good engine bay access. MAF cleaning and air filter replacement are basic tasks. Check warranty status first.
