Standard Ignition TH446 Throttle Position Sensor

Throttle Position Sensor for Mazda Applications

The Standard Ignition TH446 throttle position sensor provides direct throttle angle feedback to the engine management system. It is built with a female plug-in connector, three male blade terminals, and a sensor layout suited for precise signal transfer in Mazda throttle control systems.

Key Features

• Standard Ignition TH446 throttle position sensor
• Female connector with plug-in design
• 3-terminal configuration with male blade terminals
• Direct-fit style for listed Mazda applications
• Supports accurate throttle position signal input

Detailed Description

The TH446 is an emission control sensor used to report throttle plate movement to the vehicle control system. On Mazda 3, Mazda 6, Mazda 3 Sport, Mazda 5, and Mazda CX-7 applications, this sensor helps the engine computer interpret driver throttle input for proper fuel and air management. The Standard Ignition TH446 is a practical replacement choice when the original throttle position sensor shows signal irregularities or connector wear.

This part cross-references 2-60068 and TPS4268 for the same application. It is a fitment-based replacement for 2009-2014 Mazda 6, 2010-2015 Mazda 3, 2012-2013 Mazda 3 Sport, 2012-2013 Mazda 5, 2010 Mazda 5, and 2010-2012 Mazda CX-7.

What It Helps Address

• Throttle position signal errors
• Unstable idle caused by incorrect throttle feedback
• Delayed or inconsistent throttle response
• Check engine light conditions related to throttle sensor performance
• Driveability issues tied to worn sensor contacts or connector problems

Installation Notes and Tips

Verify connector style, terminal count, and vehicle application before installation. The TH446 uses a female plug-in connector with three male blade terminals, so matching the harness connection is important for proper fit. Confirm the sensor location on the throttle body and inspect the connector for corrosion or damaged terminals before replacing the unit.

Quality Assurance

Standard Ignition supplies replacement electrical and emission control components for service applications. The TH446 is built to meet the fitment and connection requirements listed for the specified Mazda models.
