Standard Ignition TH333 Throttle Position Sensor

Throttle Position Sensor for Isuzu Applications

The Standard Ignition TH333 throttle position sensor is built for direct replacement service on select Isuzu vehicles. It uses a female connector with a plug-in design, 2 connector cavities, and 6 male blade terminals to match the original electrical interface.

Compatible With 1988-1991 Isuzu Trooper, 1989-1990 Isuzu Pickup with Federal Emissions, 1988-1989 Isuzu Impulse, and 1988 Isuzu Pickup. This TH333 throttle position sensor supports accurate throttle signal input for drivability-focused repairs on these Isuzu models.

Key Features

• Standard Ignition TH333 throttle position sensor
• Female connector with plug-in style connection
• 2 connector cavities and 6 male blade terminals
• Direct-fit electrical layout for select Isuzu throttle bodies
• Cross-reference part numbers include 2-16685 and EC3218 for the same application

Detailed Description

The TH333 is an emission control sensor used to report throttle position to the engine management system. On the Isuzu Trooper, Isuzu Pickup, and Isuzu Impulse applications listed here, the sensor helps the vehicle computer interpret throttle movement for fuel and idle control. Standard Ignition TH333 is specified with a female plug-in connector and blade terminals to align with the original harness connection.

This part is a practical replacement choice when servicing throttle response concerns on 1988-1991 Isuzu Trooper and related Isuzu models. The TH333 part number is also useful when searching for a direct replacement throttle position sensor for Federal Emissions-equipped 1989-1990 Isuzu Pickup applications.

Common Issues This Part May Address

• Erratic throttle signal output
• Hesitation during acceleration
• Unstable idle behavior related to throttle input
• Check engine light concerns tied to throttle position sensing
• Poor drivability caused by worn sensor contacts

Installation Notes and Tips

Verify connector style, terminal layout, and throttle body mounting before installation. Confirm vehicle application by year, make, model, and emissions configuration, especially for 1989-1990 Isuzu Pickup Federal Emissions vehicles. After installation, clear diagnostic codes if needed and confirm throttle signal response with a scan tool or multimeter.

Quality Assurance

Standard Ignition parts are built for service replacement use in emission control and engine management systems. The TH333 is listed with application-specific fitment for select Isuzu vehicles, including Trooper, Pickup, and Impulse models.
