Detailed Description

Standard Ignition TH339 is a throttle position sensor used to report throttle movement to the vehicle control system. On 1995-2002 Mazda Millenia applications, this sensor helps the engine computer interpret throttle opening for fuel delivery, idle control, and drivability functions. The connector and terminal configuration are listed as female, plug-in, with 4 male blade terminals, which supports proper electrical matching during replacement. This part cross-references KJ0118911 for the same application.

What It Helps Address

• Throttle signal errors that affect acceleration response
• Rough or unstable idle caused by incorrect throttle input
• Check engine light conditions related to throttle position feedback
• Delayed or inconsistent throttle response on Mazda Millenia models
• Driveability complaints tied to worn sensor output

Installation Notes and Tips

Verify connector style, terminal count, and mounting location before installation. Compare the original sensor to Standard Ignition TH339 to confirm electrical and physical match. After installation, clear diagnostic trouble codes if present and confirm throttle signal operation with a scan tool.

Quality Assurance

Standard Ignition supplies replacement ignition and engine management components for service applications, including sensors used in emission control systems. Standard Ignition TH339 is listed for direct fitment on 1995-2002 Mazda Millenia models.
