Standard Ignition TH445 Throttle Position Sensor

Throttle Position Sensor for GM Applications

Restore accurate throttle input to the ECU with this direct-fit throttle position sensor from Standard Ignition. The TH445 is built for reliable signal transfer, helping maintain smooth engine response and efficient fuel delivery on a wide range of Chevrolet, GMC, Cadillac, and related GM vehicles.

Standard Ignition TH445 is a direct replacement for vehicles that use a 6-terminal, plug-in sensor with a female connector and male blade terminals. It is engineered to replace the damaged sensor only, which can save time compared with replacing the entire throttle body assembly.

Key Features

• Direct-fit throttle position sensor replacement
• Female connector with plug-in design
• 6 terminal blade-style connection
• Built to communicate throttle valve angle to the vehicle computer
• Quality construction for consistent electrical signal transfer
• Standard Ignition TH445 for GM throttle position sensor applications

Detailed Description

This throttle position sensor monitors throttle valve angle and sends that information to the ECU so the engine can respond correctly to driver input. When the signal becomes inaccurate or intermittent, drivability and fuel control can suffer. The TH445 is made to restore proper communication between the throttle assembly and the vehicle computer on many Chevrolet Silverado, GMC Sierra, Cadillac Escalade, and related models. This part cross-references ACDelco 19259452 for the same application.

Standard Ignition TH445 is a practical replacement when the original sensor is worn or damaged but the throttle body itself remains serviceable. It is also a strong match for long-tail searches such as throttle position sensor for 2007-2013 Chevrolet Silverado 1500, 2009-2014 GMC Yukon, and 2007-2014 Cadillac Escalade.

What It Helps Solve

• Erratic throttle response
• Incorrect throttle angle signal to the ECU
• Reduced fuel economy caused by poor throttle input data
• Driveability concerns related to sensor wear or failure
• Need to replace only the sensor instead of the full throttle body

Installation Notes and Tips

Verify connector style, terminal count, and vehicle application before installation. This sensor uses a female plug-in connector with 6 male blade terminals. Confirm the throttle body and electrical connection match the original part before replacing the unit. For fitment, this part is used on applications such as Fits 2007-2013 Chevrolet Silverado 1500, N/A; Fits 2009-2014 GMC Yukon, N/A; and Fits 2007-2014 Cadillac Escalade, N/A.
