Standard Ignition TH4 Throttle Position Sensor

Throttle Position Sensor for OE-Style Output

The Standard Ignition TH4 throttle position sensor is built for precise throttle signal control on select GM applications. It uses a fixed installed output to match OE specifications, helping maintain consistent voltage feedback for the engine control system.

Key Features

• Female connector gender with 1 connector and 3 female terminals
• Flexible polyimide film or ceramic-based circuit substrate for dimensional stability
• Noble metal contact materials for low resistance and extended service life
• Integral rotor bearings and return springs for straightforward installation
• End-of-line testing with thousands of data points to verify output voltage
• Standard Ignition TH4 coverage for service applications across multiple GM models

Detailed Description

Standard Ignition TH4 is a throttle position sensor designed for direct OE-style signal output rather than an adjustable consolidated design. That approach helps preserve the correct throttle angle feedback expected by the vehicle computer. This sensor is a strong match for 1982-1984 Chevrolet Corvette, 1982-1983 Chevrolet Camaro, 1982-1983 Pontiac Firebird, 1983-1984 Buick Skyhawk, and other listed GM applications.

The internal circuit construction uses stable substrate materials to reduce electrical drift over time, while noble metal contact alloys support consistent conductivity. Standard Ignition also validates each sensor during end-of-line testing to confirm output voltage performance before it leaves the factory. If you are replacing a worn throttle position sensor on a Chevrolet Cavalier, Cadillac Cimarron, or Pontiac J2000, the TH4 provides a direct-fit service solution.

This part cross-references Walker Products 200-1036 for the same application.

What It Helps Fix

• Erratic throttle signal readings
• Hesitation during acceleration
• Rough idle caused by incorrect throttle feedback
• Check engine light concerns related to throttle position input
• Driveability issues on GM throttle body and fuel-injected applications

Installation Notes and Tips

Verify connector style and terminal count before installation. The TH4 uses a female connector with 3 female terminals, so the harness side must match. Confirm the vehicle application against the listed fitment before replacing the sensor, and inspect the throttle shaft area for wear or contamination that could affect sensor operation.

Quality Assurance

Standard Ignition maintains quality control throughout manufacturing, from component selection to finished product testing. Each TH4 throttle position sensor is tested at the end of the line to validate voltage output and support trouble-free operation.
