P0101 on Nissan
Mass or Volume Air Flow Sensor Circuit Range/Performance
P0101 on Nissan vehicles indicates mass or volume air flow sensor circuit range/performance. Au7o has documented this code across 3 Nissan models — most commonly on Kicks, Sentra, Versa. This powertrain code means the mass air flow (MAF) sensor's reading is out of the expected range or not changing as it should compared to other engine data. The MAF sensor measures how much air enters the engine so the computer can calculate the correct fuel amount. When the reported airflow doesn't match expectations, the air-fuel mixture can be off, causing rough running, hesitation, stalling, or poor fuel economy. It is usually not an emergency but should be fixed for proper performance and emissions. Typical repair costs on Nissan range from $10 to $250, depending on the specific model and root cause.
Common Causes of P0101
- •Dirty or contaminated MAF sensor element
- •Vacuum/intake air leak (unmetered air after the sensor)
- •Loose, cracked, or torn intake air ducting
- •Dirty or clogged air filter
- •Faulty MAF sensor
- •Wiring or connector problems at the MAF sensor
P0101 on Nissan by Model
Nissan Kicks(1 issue)
- Engine Stalling / Shutting Off While Driving (Throttle Body, MAF Sensor, ECM Software)2018-2020
Many 2018-2020 Kicks owners report the engine stalling or shutting off, often when slowing to a stop and in some cases at speed, sometimes with a delayed restart. Dealers and forums commonly trace it to the throttle body, a contaminated mass airflow (MAF) sensor, or outdated ECM software; throttle-body replacement and ECM reprogramming have resolved repeat cases. RepairPal documents engine-stalling as a recognized Kicks complaint, frequently alongside DTC P0101.
Nissan Sentra(1 issue)
- Mass Air Flow Sensor Contamination and Failure2007-2019
The Sentra MAF sensor is prone to contamination and failure, causing driveability issues. Oil from aftermarket air filters (especially oiled cotton filters) or crankcase ventilation can coat the hot wire element, causing incorrect air flow readings. This leads to poor fuel mixture calculations, hesitation, and stalling. Even with stock air filters, the MAF sensor can fail due to age and heat cycling.
Nissan Versa(1 issue)
- Mass Air Flow Sensor Failure2007-2019
The Nissan Versa MAF sensor is prone to contamination and failure, particularly on the HR16DE 1.6L engine. The hot wire element becomes contaminated with oil vapors from the PCV system and dirt that passes through the air filter. This causes incorrect air flow readings, leading to poor engine performance, hesitation, and increased emissions. The issue often presents intermittently before becoming a constant problem.
