The 2023 Dodge Charger triggering P0101 indicates the mass air flow sensor readings are outside expected range for the current operating conditions. This performance sedan's V6 or V8 engine depends on accurate MAF data for proper fuel delivery.
Understanding P0101
P0101 sets when MAF sensor readings don't correlate with other data like throttle position, RPM, and load. The readings may be too high, too low, or erratic. This code indicates a performance problem rather than complete sensor failure.
Charger Engine Options
The 2023 Charger offers 3.6L Pentastar V6 and 5.7L/6.4L HEMI V8 engines. Each uses a MAF sensor in the intake tract. Sensor location varies slightly but diagnosis procedures are similar.
Common MAF Causes
Contaminated MAF sensor elements from dirty air filters or oil from aftermarket filters. Air leaks between the MAF and throttle body. Damaged sensing element from physical contact. Wiring issues affecting sensor signals.
MAF Cleaning
MAF sensors can often be restored by cleaning with MAF-specific cleaner. Never touch the sensing element. Spray the cleaner on the element and allow to dry completely before reinstalling.
Air Leak Detection
Air entering after the MAF isn't measured, causing incorrect fuel calculations. Check for cracks in the air intake tube, loose clamps, or gasket leaks at the throttle body.
Repair Costs
MAF sensor cleaning costs $50-100 if DIY. MAF sensor replacement runs $150-350. Air intake tube replacement costs $100-300. Throttle body gasket replacement runs $100-200.
