C-Tzu Mass Air Flow Sensor MAF 22680-5J000 / 22680-7B001 Direct-Fit for Nissan Infiniti (OEM-Equivalent)

The C-Tzu Mass Air Flow Sensor 22680-5J000 / 22680-7B001 is a direct-fit replacement MAF assembly engineered to restore accurate airflow readings and help your engine run more smoothly.

If your vehicle shows symptoms like rough idle, fluctuating RPMs, decreased fuel efficiency, or a Check Engine light tied to airflow measurement, a failing mass air flow (MAF) sensor is often the culprit. The C-Tzu MAF sensor provides an OEM-equivalent option that fits multiple Infiniti, Nissan, Mercury and Ford applications, matching factory dimensions and electrical connections so installation is straightforward for DIYers and technicians alike.

How will this MAF sensor affect engine performance?

Accurate airflow data is essential for the engine control unit (ECU) to deliver the correct fuel-to-air ratio. Replacing a faulty MAF sensor helps stabilize idle, reduce hesitation during acceleration, and can improve fuel economy when the sensor returns proper readings to the ECU.

• Restores correct air measurement to engine management systems
• Can reduce rough idling and stalling when readings were previously erratic
• Supports smoother throttle response and more consistent acceleration
• Helps vehicle reach optimal air-fuel mixture for combustion efficiency

Is this C-Tzu sensor compatible with my vehicle?

The C-Tzu assembly replaces several OEM numbers including 22680-5J000, 22680-7B001, 22680-7B000 and related equivalents found across Nissan, Infiniti, Mercury, and Ford models. Compatibility depends on year, engine and connector type—always compare part numbers or consult your service manual before ordering.

• Replaces listed OE numbers for easy cross-reference
• Fits models such as Infiniti QX4, Nissan Frontier/Pathfinder/Quest/Xterra, Mercury Villager, Ford Mustang
• Check vehicle year, engine code, and connector shape before purchase
• Direct-fit design minimizes modifications and wiring changes

What should I expect during installation and service life?

Installation is typically plug-and-play where the original sensor mounts and electrical connector are unchanged. The C-Tzu unit is built with quality materials for durability, and it comes backed by a one-year warranty to cover manufacturing defects.

• Direct replacement for factory location—no custom brackets required
• Standard electrical connector and mounting points for quick swap
• Durable housing and sensing element designed for long-term use
• 1-year warranty for peace of mind against defects

How can I tell if I need to replace the MAF sensor?

Signs of a failing MAF sensor include persistent Check Engine light codes related to airflow, noticeable fuel economy decline, or rough running that cleaning doesn’t fix. Use diagnostic trouble codes (DTCs) and visual inspection for dirt, damage, or connector corrosion to determine if replacement is necessary.

• Diagnostic codes like P0100–P0104 often indicate MAF issues
• Physical problems include cracked housing, contaminated sensing element, or corroded pins
• Intermittent drivability problems that cleaning won’t cure suggest replacement
• A new sensor helps the ECU recalibrate fueling accurately

Who this is for: The C-Tzu Mass Air Flow Sensor 22680-5J000 / 22680-7B001 is aimed at vehicle owners, independent mechanics, and fleet technicians who need a reliable, OEM-equivalent MAF replacement without the premium price of factory parts. It suits drivers of compatible Infiniti, Nissan, Mercury, and Ford vehicles who want a straightforward swap to address airflow-related drivability or emissions issues while maintaining long-term reliability.
