Standard Ignition TH345 Throttle Position Sensor

Throttle Position Sensor for Volkswagen Applications

Standard Ignition TH345 is a throttle position sensor built for direct-fit service on select Volkswagen models. It uses a female plug-in connector with three male blade terminals to support a straightforward electrical connection at the throttle body.

Compatible With 2003 Volkswagen Derby, 1993-1997 Volkswagen Golf, 1995-1996 Volkswagen Cabrio to VIN 1ES040000, 1993-1995 Volkswagen Jetta, and 1995 Volkswagen Passat. This Standard Ignition TH345 throttle position sensor is a practical replacement when diagnosing throttle signal issues on Volkswagen Golf, Jetta, and Passat applications.

Key Features

• Throttle position sensor for emission control and engine management systems
• Female connector with plug-in design for a direct electrical interface
• Three male blade terminals for the specified vehicle connection
• Built for select Volkswagen fitments, including Golf, Jetta, Cabrio, Passat, and Derby
• Cross-reference part numbers include 2-16713 and EC3246 for the same application

Detailed Description

The Standard Ignition TH345 monitors throttle angle and sends the signal needed by the engine control system to interpret driver input. Accurate throttle position feedback is important for fuel delivery, idle control, and overall drivability on compatible Volkswagen models. If you are replacing a worn sensor on a 1993-1997 Volkswagen Golf or a 1993-1995 Volkswagen Jetta, TH345 provides the specified connector and terminal configuration for the application.

This part cross-references 2-16713 and EC3246 for the same application. Use TH345 when servicing throttle position sensor concerns on Volkswagen Cabrio, Passat, and Derby vehicles listed in the fitment data.

What It Helps Address

• Erratic or unstable idle speed
• Throttle response that feels delayed or inconsistent
• Check engine light related to throttle position signal faults
• Poor fuel metering caused by incorrect throttle input data
• Driveability issues during acceleration or deceleration

Installation Notes and Tips

Verify connector style, terminal layout, and vehicle fitment before installation. Inspect the throttle body connector and wiring for corrosion, bent terminals, or damaged locking tabs before connecting the new sensor. After installation, clear diagnostic trouble codes and confirm throttle signal operation with a scan tool if required by the vehicle service procedure.

Quality Assurance

Standard Ignition is a recognized aftermarket brand for electrical and engine management components. TH345 is specified for the listed Volkswagen applications and built to match the required connector and terminal configuration.
