Dorman 645-183 Mass Air Flow Sensor Connector

Dorman 645-183 is a female mass air flow sensor connector built for electrical repair work on Ford, Lincoln, and Mercury applications that use a 6-cavity MAF plug. It provides a direct service solution for damaged connector bodies, broken terminals, and intermittent sensor connections on vehicles such as the Ford F-150, Ford Focus, and Lincoln MKZ.

Key Features

• Female 6-cavity mass air flow sensor connector for emission control electrical repair
• Black, green, and red wire color identification for organized circuit work
• 18-gauge wiring with an 11.18-inch harness length
• Rectangular oval connector shape with blade-style terminals
• Engineered for quick circuit disconnection during service
• Direct replacement style for common Ford, Lincoln, and Mercury MAF connector repairs

Detailed Description

This Dorman pigtail connector is designed for repairing the electrical side of the mass air flow sensor circuit when the original connector is heat-damaged, corroded, or physically worn. The female terminal design and 6-wire layout support a clean connection at the sensor, while the rectangular oval housing helps match the OE-style interface used across many Ford platforms. Part number 645-183 is a practical choice for restoring signal integrity on vehicles including the Ford F-150, Ford Explorer, and Lincoln MKZ.

This part cross-references Standard Ignition S2371 for the same application.

Common Repair Uses

• Broken or loose MAF sensor connector terminals
• Heat damage at the connector body near the air intake system
• Corrosion or contamination causing unstable sensor readings
• Intermittent check engine light concerns tied to MAF circuit faults
• Wiring repairs after harness damage during service or diagnosis

Installation Notes and Tips

Verify the vehicle uses a 6-cavity mass air flow sensor connector before installation. Match each wire position carefully to the original harness layout, and confirm secure terminal engagement after crimping and splicing. For best results, inspect the sensor side of the connector and surrounding harness for heat damage, broken locks, or corrosion before completing the repair. Compatible With 2004-2019 Ford F-150, 2004-2018 Ford Focus, and 2013-2017 Lincoln MKZ when the application calls for a 6-cavity connector.
