Standard Ignition TH297 Throttle Position Sensor

Throttle Position Sensor for OE-Style Output

Standard Ignition TH297 is a throttle position sensor built for direct replacement service on select Cadillac CTS and Chevrolet Corvette applications. It uses a fixed installed output to match OE calibration, helping maintain consistent throttle signal feedback for accurate engine management.

Compatible With 2004-2005 Cadillac CTS and 1997-2004 Chevrolet Corvette, this TH297 throttle position sensor is built around stable circuit materials, low-resistance contact alloys, and end-of-line voltage testing for dependable signal performance.

Key Features

• Female connector with plug-in connection style
• 6 male blade terminals for OE-style electrical interface
• Flexible polyimide film or ceramic-based circuit construction for dimensional stability
• Palladium, gold, and platinum alloy contacts for low resistance and extended service life
• Integral rotor bearings and return springs for easier installation
• End-of-line testing with thousands of data points to verify output voltage
• Standard Ignition TH297 throttle position sensor for emission control repair

Detailed Description

The TH297 throttle position sensor monitors throttle angle and sends the signal the engine control system uses to manage fuel delivery, idle behavior, and acceleration response. Standard Ignition builds this sensor with a fixed installed output rather than an adjustable consolidated design, which helps preserve OE-style calibration on the vehicle. The result is a direct-fit emission control sensor for 2004-2005 Cadillac CTS and 1997-2004 Chevrolet Corvette service work.

This part cross-references Delphi SS10468 for the same application. Standard Ignition TH297 is also referenced in aftermarket catalogs under related numbers such as 75458 for application matching.

What It Helps Address

• Throttle signal irregularities that affect acceleration response
• Idle instability caused by inaccurate throttle position feedback
• Check engine lights related to throttle position sensor faults
• Driveability concerns tied to worn sensor contacts or drifting output
• Emission control issues caused by inconsistent throttle input data

Installation Notes and Tips

Verify connector style, terminal count, and throttle body application before installation. The TH297 uses a female plug-in connector with 6 male blade terminals, so the mating harness and sensor orientation should match the original unit. After installation, clear diagnostic trouble codes and confirm throttle signal output with a scan tool or voltmeter.

Quality Assurance

Standard Ignition manufactures emission control components with process control from component selection through finished product testing. Each TH297 sensor is tested at the end of the line to confirm output voltage consistency before it leaves the factory.
