Function and Application

The Standard Ignition TH50 throttle position sensor monitors the position of the throttle valve and sends this data to the engine control unit (ECU). This information is critical for fuel injection timing, ignition timing, and transmission shifting. It helps address issues such as:

• Erratic or unstable idle speed
• Poor acceleration response
• Engine stalling or hesitation
• Check engine light related to throttle position sensor faults
• Transmission shifting problems in compatible models

Installation Notes and Tips

When installing the TH50 throttle position sensor, ensure the vehicle’s ignition is off and the battery is disconnected to prevent electrical shorts. Carefully disconnect the existing sensor’s wiring harness, noting the connector orientation. The male connector with one connection point and three female terminals should align precisely with the vehicle’s wiring. Avoid forcing the connector to prevent damage to terminals. After installation, clear any diagnostic trouble codes and verify sensor operation with a scan tool.
