Detailed Description

NTK AU0161 is an automatic transmission speed sensor engineered for vehicles that require input-speed feedback to the transmission control system. The connector and terminal layout are specified for the listed Ford Freestar, Mercury Monterey, Ford Taurus, Mercury Sable, and Ford Windstar applications, including the noted stamping requirements on certain Taurus and Sable models. As part of the NTK Sensor Specialist line, AU0161 reflects OE-focused sensor development and testing practices used across NTK technical sensors.

This part cross-references Dorman - OE Solutions 917-663 and Standard Ignition SC212 for the same application.

What It Helps Address

• Erratic or missing transmission input speed signal
• Transmission shifting concerns tied to sensor feedback
• Illuminated transmission or powertrain fault codes related to speed sensing
• Incorrect sensor readings caused by connector or terminal mismatch
• Fitment issues on applications requiring the listed stamping-specific sensor

Installation Notes and Tips

Verify the vehicle year, make, model, and input position before ordering. Confirm the connector shape, connector gender, and terminal count match the original sensor, and check the stamping number on 2001-2003 Taurus and Sable applications. Wiring harness and mounting hardware are not included.

Quality Assurance

NTK draws on more than 80 years of automotive experience and OE sensor development. This sensor is manufactured to meet or exceed OE specifications and is tested under thermal shock, vibration, and OBD verification conditions.
