Williams Controls 134168 | Throttle Position Sensor Kit for Paccar & Cummins
The 134168 williams control Throttle Position Sensor is a professional-grade 134168 TPS Sensor kit designed specifically for Kenworth, Peterbilt, and Cummins-powered commercial vehicles, featuring IP66 sealing and an integrated USA-made wire harness for ultimate reliability.
Product Features
Engineering Data: High-Performance williams control 134168
Comprehensive APP Sensor Kit
The 134168 is more than a sensor; it is a full 134168 TPS replacement solution. The kit includes the sensor, high-quality mounting screws, and a custom wire harness assembled in the USA, eliminating common failure points at the electrical connection interface.
Ratiometric Precision and Redundancy
Utilizing a dual-channel output, the sensor provides independent APS and IVS signals. This WCS 134168 design allows the vehicle ECM to perform safety cross-checks, preventing unintended acceleration and ensuring the engine returns to idle reliably when the pedal is released.
Industrial Durability
With an IP66 rating and a specialized ABS/thermoplastic housing, the 134168 is built to endure millions of “dither” cycles caused by road vibrations and heat cycling in heavy-duty commercial environments.

Industrial Applications
Class 8 Logistics (Paccar)
The 134168 is the gold standard for Kenworth and Peterbilt long-haul rigs. It maintains precise throttle management over millions of miles, resisting the signal “noise” common in heavy-duty tractor electrical systems.
Vocational & Construction
Found in refuse trucks and heavy vocational vehicles, the sensor’s IP66 rating and chemical resistance make it ideal for environments where high-pressure cleaning and caustic debris are present.
Public Transit
Reliability in bus systems is critical. The 134168 ensures that transit buses with Cummins powerplants operate with smooth, predictable acceleration, reducing drivetrain wear and increasing passenger safety.

FAQ
Common Technical Questions for Williams Controls 134168
How do I know if I need the 134168 or the 134169?
While electronically similar, these sensors often differ by harness orientation. Check your OEM part number; if the 134169 is specified, the harness in the 134168 may not reach or fit the mounting bracket properly.
Is this a genuine Williams Controls part?
Yes, this kit features the genuine 134168 sensor manufactured to Curtiss-Wright’s rigorous quality standards, ensuring compatibility with factory ECM programming.
Can I install this on a Detroit Diesel engine?
No, the 134168 kit is specifically designed for Paccar and Cummins engine platforms. Detroit Diesel systems typically require a different pin configuration and harness connector.
What tools are needed for the swap?
Standard hand tools are sufficient for the physical mounting. However, a scan tool is recommended to clear existing “Throttle Position Sensor Performance” codes from the ECM memory.
