NTK AD0451 Accelerator Pedal Sensor

Accelerator Pedal Sensor Overview

NTK Accelerator Pedal Sensor AD0451 is a technical sensor built for direct replacement applications where pedal position input must be read accurately and consistently. It is engineered with OE-focused testing and coverage for import and domestic vehicles, including Buick Allure, Buick LaCrosse, and Chevrolet Impala applications.

As part of the NTK sensor line, AD0451 reflects the brand’s OE experience and its focus on expanding full-line sensor coverage under one product family. The sensor uses a 6-terminal blade connection with an oblong female connector for a precise electrical interface.

• 6-terminal blade design for secure electrical connection
• Oblong female connector shape for proper harness interface
• Built as an accelerator pedal sensor for throttle input signal reading
• OE-focused testing includes thermal shock, vibration, and OBD verification
• NTK technical sensor coverage for import and domestic applications

Detailed Product Information

AD0451 is an accelerator pedal sensor that translates pedal movement into an electrical signal used by the vehicle control system. NTK manufactures this sensor to meet or exceed OE specifications, using validation methods that reflect real-world electrical and environmental stress. For buyers searching for a Buick Allure accelerator pedal sensor, Buick LaCrosse accelerator pedal sensor, or Chevrolet Impala accelerator pedal sensor, this part number provides a direct replacement option backed by NTK’s sensor specialization. This part cross-references Dorman - OE Solutions 699-104 and Standard Ignition APS128 for the same application.

Common Replacement Issues

• Unstable or inconsistent accelerator pedal signal
• Throttle response problems caused by sensor wear
• Fault codes related to pedal position input
• Driveability concerns tied to inaccurate pedal feedback

Installation Notes

Verify connector shape, terminal count, and harness style before installation. This sensor uses a female oblong connector with blade terminals, so matching the electrical interface is important for proper fitment. Confirm vehicle application by year, make, and model before ordering.

Quality Assurance

NTK draws on more than 80 years of automotive experience and OE sensor development. AD0451 is tested under thermal shock, vibration, and OBD verification conditions to support OE-level performance expectations.
