• Female connector with plug-in style connection
• 3 male blade terminals for the electrical circuit
• Single connector design for straightforward harness matching
• Standard Ignition TH405 reference for catalog and cross-check use

Detailed Description

The Standard Ignition TH405 throttle position sensor reports throttle opening to the engine control system so fuel delivery, idle control, and shift strategy can respond to driver input. Its connector layout includes one female plug-in connector and three male blade terminals, which helps match the original electrical interface on supported applications. When replacing a worn throttle position sensor on Nissan or Suzuki models, TH405 is a direct part number to verify against the original unit.

This part cross-references 2-60027 and TPS4189 for the same application.

What It Helps Address

• Erratic throttle signal readings
• Delayed or inconsistent throttle response
• Idle instability related to throttle position feedback
• Check engine light concerns tied to throttle sensor output
• Driveability issues caused by a failing TPS

Installation Notes and Tips

Before installation, compare the connector style, terminal count, and terminal type to the original sensor. Confirm the throttle body mounting and electrical indexing match the vehicle’s OE configuration. After installation, clear diagnostic trouble codes and verify throttle signal output with a scan tool or multimeter.

Quality Assurance

Standard Ignition is a long-established aftermarket brand known for electrical and engine management components. TH405 should be verified against the original part number and connector layout before installation to confirm application match.
