MAF Air Flow Meter Sensor For Nissan Navara 1985 - 2018 D21 D22 D23 D40 reliable replace to determine the Flow Mass rate of Air entering a fuel-injected internal combustion engine. Compatible with OEM 22680-7S000, MF21058N, 336-60644. The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine.  It is an important part of reducing exhaust and air supply. Used to measure the amount of air entering the engine so that the engine control module can determine the amount of fuel to be injected.

What does a mass flow sensor do?

• What Does it Do? Mass air flow sensors measure the air mass flowing into the engine intake

 

How do I know if I need a new AFM sensor?

• The engine is very hard to start or turn over. The engine stalls shortly after starting. The engine hesitates or drags while under load or idle. Hesitation and jerking during acceleration

 

What are the symptoms of a failing mass air flow sensor? Seven Signs Your Mass Airflow Sensor Is Dirty Or Going Bad

• Black Exhaust. One sign that your vehicle's MAF is going bad is black exhaust from excess fuel
• Check Engine. A faulty mass airflow sensor is a common reason why a check engine light comes on
• Hard Starts
• Hesitation
• Poor Gas Economy
• Rough Idle
• Trouble Accelerating

 

What happens when a mass flow sensor fails?

• A bad MAF sensor can cause your vehicle to experience poor drivability issues such as engine stalling, jerking or hesitation during acceleration. This could happen while speeding up on the highway on-ramp or cruising down a city street. These issues can create dangerous situations causing accidents and injury.

 

How to replace MAF sensor?

• Step 1: Disconnect the electrical connector from the mass air flow sensor
• Step 2: Disconnect the mass air flow sensor
• Step 3: Connect the new mass airflow sensor
• Step 4: Reconnect the electrical connector
