Product Features
134734 williams control
Non-Contacting Hall Effect Technology
The 134734 sensor utilizes advanced magnetic sensing instead of traditional contact-based wipers, achieving a mechanical life of over 10,000,000 cycles.
Dual Redundant APS Signals
Safety is prioritized through a dual redundant APS architecture, allowing the vehicle’s ECM to perform real-time parity checks and safety routines.
IP67 Sealed Environmental Protection
Designed for the harshest industrial conditions, featuring an IP67-rated enclosure that ensures protection against dust and water immersion.
Applications
Wil 134734
- Heavy-Duty Commercial Trucking: The 134734 is a primary choice for Class 7 and 8 trucks, specifically serving as a direct replacement for Navistar International and Mack platforms. Its high reliability ensures consistent throttle response across millions of miles.
- Off-Highway and Construction Equipment: Due to its IP66 rating and non-contact design, this sensor is widely integrated into excavators and loaders. It resists the ingress of abrasive dust and maintains precision even during extreme chassis vibration.
- Agricultural Machinery: Used in modern tractors and harvesters, the 134734 provides the sensitive throttle feedback required for precision agricultural tasks while withstanding constant heat cycling in open-field environments.
- Marine Propulsion Systems: The hermetically sealed electronics make it suitable for marine engine controls where moisture and salt-spray corrosion would typically compromise contact-based sensors.
- Power Generation Sets: In stationary diesel generators, the dual-channel redundancy of the 134734 ensures stable engine governor control, which is vital for maintaining consistent frequency and voltage in critical power applications.

FAQ
williams controls 134030
Is the 134734 compatible with Detroit Diesel engines?
Generally, no. This sensor is calibrated specifically for Cummins Engines (2007+). While it physically fits some other models, you must verify the OEM part number to ensure the voltage slope matches your ECU requirements.
Why are there two different voltage ranges for APS1 and APS2?
This is a standard safety feature. APS1 (22-84%) and APS2 (11-42%) provide a “half-slope” redundancy. If the signals do not correlate correctly, the ECU identifies an electrical fault to prevent unintended acceleration.
How do I recalibrate the sensor after installation?
With the ignition in the ON position, slowly and fully depress the accelerator pedal from idle to full throttle. Repeat this procedure three times to allow the ECU to learn the new sensor’s operating range.
Does this kit include a mating connector?
The sensor features an integral Metri-Pack 150 6-pin interface. While the sensor kit (134734) is a direct replacement for the 134030, the mating harness is typically part of the vehicle’s original wiring loom.
