Standard Ignition TH374 Throttle Position Sensor

Throttle Position Sensor for Toyota and Geo

Standard Ignition TH374 is a throttle position sensor built for precise throttle angle feedback in older Toyota and Geo applications. It uses a female plug-in connector with three male blade terminals for direct electrical connection in the throttle body circuit.

Key Features

• Throttle position sensor for emission control and engine management systems
• Female connector with 1 plug-in connection point
• 3 male blade terminals for secure signal transfer
• Direct-fit replacement for select Toyota, Geo, and Chevrolet applications
• Standard Ignition TH374 for service and repair work

Detailed Description

Standard Ignition TH374 is a replacement throttle position sensor used to report throttle opening to the engine control system. Accurate throttle position input helps the vehicle manage fuel delivery, idle response, and drivability across a range of older Toyota Celica, Toyota Corolla, Toyota Van, Toyota Cressida, Geo Metro, and Chevrolet Sprint applications. This part cross-references 2-19297 and EC3099 for the same application.

Compatible With 1990-1993 Toyota Celica, 1989-1991 Geo Metro, 1990 Toyota Corolla, 1989 Chevrolet Sprint, 1984-1989 Toyota Van, and 1980-1984 Toyota Cressida. Standard Ignition TH374 is a practical choice when replacing a worn throttle position sensor on these vehicles.

Common Issues This Part May Address

• Erratic or delayed throttle response
• Rough idle caused by incorrect throttle signal input
• Hesitation during acceleration
• Check engine light related to throttle position sensor faults
• Inconsistent fuel control from a worn sensor

Installation Notes and Tips

Verify connector style, terminal count, and vehicle application before installation. Inspect the throttle body connector and wiring for corrosion, looseness, or damaged terminals before connecting the new sensor. After installation, confirm throttle signal output and idle behavior with the engine running.

Quality Assurance

Standard Ignition supplies replacement electrical components for service applications, and TH374 is built to match the connector and terminal configuration used on the listed vehicles. Confirm fitment by year, make, and model before ordering.
