P0102 on Nissan
Mass or Volume Air Flow Sensor Circuit Low Input
P0102 on Nissan vehicles indicates mass or volume air flow sensor circuit low input. Au7o has documented this code across 2 Nissan models — most commonly on Sentra, Versa. P0102 is a generic OBD-II code meaning the engine computer detected an abnormally low voltage or signal from the Mass Air Flow (MAF) sensor circuit. The MAF sensor measures how much air is entering the engine so the computer can deliver the correct amount of fuel. A low signal tells the computer it is reading less airflow than is actually present, which can cause poor running, stalling, or reduced power. While not usually an emergency, it can affect drivability and fuel economy and should be addressed. Typical repair costs on Nissan range from $10 to $250, depending on the specific model and root cause.
Common Causes of P0102
- •Dirty or contaminated MAF sensor element
- •Faulty MAF sensor
- •Damaged, corroded, or loose MAF connector/wiring
- •Open or short to ground in the signal or power circuit
- •Dirty or restricted air filter / intake blockage
- •Vacuum or intake air leak after the sensor
- •Poor power or ground supply to the sensor
P0102 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.
