P0100 on Nissan
Mass or Volume Air Flow Circuit Malfunction
P0100 on Nissan vehicles indicates mass or volume air flow circuit malfunction. Au7o has documented this code across 2 Nissan models — most commonly on Sentra, Versa. This generic code means the PCM detected a problem in the mass air flow (MAF) sensor circuit. The MAF sensor measures how much air enters the engine so the computer can deliver the correct amount of fuel, and a circuit fault disrupts that measurement. The result can be poor performance, rough running, hesitation, or stalling, along with reduced fuel economy. Typical repair costs on Nissan range from $10 to $250, depending on the specific model and root cause.
Common Causes of P0100
- •Faulty or contaminated mass air flow sensor
- •Dirty MAF sensor element
- •Damaged wiring or connector at the MAF sensor
- •Vacuum or intake air leak
- •Dirty or restricted air filter
- •Loose or cracked intake ducting
- •Faulty PCM (rare)
P0100 on Nissan by Model
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.
