Product Details

Walker Products has supplied automotive fuel system and sensor components since 1946, with a focus on OE-style fit and specification control. Part number 200-1478 is part of the Walker Products engine sensor line and is intended for throttle position sensor replacement where precise throttle input reporting is required. For drivers and technicians servicing a throttle position sensor on a Honda Civic or similar application, this part supports accurate signal transfer to the engine control system.

This throttle position sensor is used in applications where the throttle body position must be communicated to the ECU for fuel delivery, idle strategy, and transmission response. Walker 200-1478 is a practical replacement choice when restoring throttle response and sensor output consistency.

Common Issues It May Solve

• Erratic or delayed throttle response
• Check engine light related to throttle position sensor faults
• Rough idle caused by incorrect throttle signal input
• Hesitation during acceleration
• Unstable fuel control from inaccurate throttle angle readings

Installation Notes and Tips

Verify connector style, mounting pattern, and calibration requirements before installation. After replacement, clear diagnostic trouble codes and confirm throttle signal output with a scan tool. For Honda Civic throttle position sensor service, confirm the sensor is indexed correctly and that the throttle body is clean before final testing.

Quality Assurance

Walker Products manufactures engine management components to meet or exceed OEM standards and specifications. The company supports production with its own engineering, product management, and technical teams to help maintain application accuracy and part quality. Walker 200-1478 reflects that OE-focused approach for throttle position sensor replacement.
