Standard Ignition TH386 Throttle Position Sensor

Throttle Position Sensor for Saturn SC1 SC2 SL

Standard Ignition TH386 is a throttle position sensor built for direct OE-style output on select Saturn applications. It is engineered for 1998-1999 Saturn SC1, SC2, SL, SL1, SL2, SW1, and SW2 models, with a female plug-in connector and 3 male blade terminals for a straightforward electrical connection.

Key Features

• Direct replacement throttle position sensor for select Saturn vehicles
• Female connector with 1 plug-in connection
• 3 male blade terminals for OE-style interface
• Flexible polyimide film or ceramic-based circuit construction for dimensional stability
• Noble metal contact materials for low resistance and long service life
• Integral rotor bearings and return springs for easier installation
• End-of-line testing with thousands of data points to verify output voltage

Detailed Description

Standard Ignition TH386 is designed to maintain a specific installed output that matches OE requirements rather than using an adjustable consolidated design. That matters on throttle position sensor applications where accurate voltage feedback is needed for proper engine management. This part cross-references 5S5317 and TPS153 for the same application. Compatible With 1998-1999 Saturn SC1, 1998-1999 Saturn SC2, and 1998-1999 Saturn SL family vehicles, TH386 supports consistent throttle signal delivery for drivability-focused repairs. It is also a direct service option for 1998-1999 Saturn SW1 and SW2 models.

What It Helps Address

• Throttle signal irregularities that can affect acceleration response
• Rough or inconsistent idle caused by incorrect throttle feedback
• Check engine light concerns related to throttle position sensor output
• Driveability issues tied to worn sensor contacts or unstable voltage readings
• Service replacement needs on Saturn SC1, SC2, SL, SL1, SL2, SW1, and SW2 models

Installation Notes and Tips

Verify connector style and terminal count before installation: TH386 uses a female connector, one plug-in connection, and 3 male blade terminals. Confirm the sensor is indexed correctly on the throttle body and follow the vehicle service procedure for throttle position adjustment or relearn steps if required by the application. For best results, inspect the connector terminals and wiring for corrosion or damage before installing the new sensor.

Quality Assurance

Standard Ignition manufactures emission control components with process control from component selection through finished product. TH386 is tested at the end of the line using thousands of data points to validate output voltage and help ensure stable operation in service.
