P0102 on Nissan by model: symptoms, diagnosis and fix
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.
Common Symptoms
- Hesitation during acceleration
- Engine stalling at idle
- Poor fuel economy
- Check engine light with P0101 or P0102
- Rough idle
How to Fix
First attempt: Clean the MAF sensor with dedicated MAF sensor cleaner spray ($8-12). Do NOT use carburetor cleaner or brake cleaner as they can damage the sensor. If cleaning does not resolve the issue, replace the MAF sensor ($80-150 for aftermarket, $150-250 OEM). The sensor is located in the intake tube between the air filter and throttle body and takes 10 minutes to replace.

- CRC 05110 Mass Air Flow Sensor Cleaner 11 oz
Chemical cleaner, not a sensor and not vehicle-specific. Use only on a removed/cooled MAF element exactly as directed; never substitute carburetor or brake cleaner.
- Genuine Nissan MAF sensor 22680-7S000
Confirm VIN and connector; not B17.
- Genuine Nissan MRA8DE MAF sensor 22680-1MG0A
Confirm VIN/build date because 2015-2016 catalogs can overlap the 5RB0A branch.
- Genuine Nissan MAF sensor 22680-5RB0A
Confirm VIN/build date and connector.

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.
Common Symptoms
- Hesitation on acceleration
- Rough idle
- Poor fuel economy
- Check engine light with P0101
- Engine stalling
How to Fix
Clean the MAF sensor with CRC MAF Sensor Cleaner spray ($8-12). If cleaning does not resolve the issue, replace the MAF sensor. Aftermarket sensors cost $50-100; OEM Nissan sensors cost $120-200. The sensor is located in the air intake tube and takes 5-10 minutes to replace with basic tools. Ensure the air filter is clean and properly seated after MAF service.

Only diagnosis- and fitment-reviewed repair parts are linked here.
- CRC 05110 Mass Air Flow Sensor Cleaner 11 oz
Use only on the removed MAF element per label; do not use brake/carburetor cleaner or touch the element.
- Genuine Nissan early Versa MAF 22680-7S000
2007-2019 Versa catalog range across HR16DE/MR18DE, but later production may use 5RB0A; VIN/production-date confirmation required.
- Genuine Nissan later Versa MAF 22680-5RB0A
Confirm VIN because catalog overlap exists.

Frequently asked questions
What does P0102 mean on a Nissan?
P0102 stands for "Mass or Volume Air Flow Sensor Circuit Low Input." 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. On Nissan it is documented across 2 models: Sentra, Versa.
What are the most common causes of P0102?
The most common causes of P0102 are: 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. The specific cause varies by vehicle.
How much does it cost to fix P0102 on a Nissan?
Published repair estimates on Nissan range from $10 to $250 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
