2607117C91 Non-Contact Throttle Position Sensor
The 2607117C91 is engineered to provide a dual ratiometric accelerator position sensor (APS) output, a design choice that fulfills the stringent safety and redundancy requirements of modern electronic engine control units (ECUs).
Williams Controls 2607117C91 Non-Contact Throttle Position Sensor
The Williams Controls 2607117C91 is a high-precision, dual-channel non-contact rotary position sensor designed for heavy-duty Cummins engines (2007+), providing IP66-rated durability and fail-safe dual APS output for superior throttle control reliability.
Product Features
Williams Controls 2607117C91 : High-Performance Dual APS Sensing Solution
Non-Contact Hall-Effect Technology
By utilizing solid-state Hall-effect sensing, the 2607117C91 eliminates mechanical wear caused by sliding contacts. This design provides an operational life of over 10 million full cycles and is immune to the signal degradation caused by road vibrations and engine dither.
Dual Isolated APS Channels
The sensor incorporates two completely independent, electrically isolated Accelerator Position Sensor (APS) circuits. This architecture ensures maximum fault tolerance, allowing the ECU to compare signals and enter a safety “limp mode” if a discrepancy is detected.
Extreme Environmental Resilience
Encased in a precision-molded ABS housing, the unit is IP66 rated for dust and water ingress protection. It is engineered to withstand the harsh thermal and chemical environments of heavy-duty engine compartments, operating from -40°C to +85°C.

FAQ
Common Technical Inquiries for Williams Controls 2607117C91
Is the 2607117C91 compatible with Detroit Diesel engines?
Generally, no. It is designed for Cummins Engines (2007+). Check your vehicle’s original part number before installation.
Why does it have two different voltage ranges?
This is a safety cross-check. APS1 (22-84%) and APS2 (11-42%) allow the ECU to detect signal shorts immediately.
How do I recalibrate the sensor?
Turn the ignition ON, then slowly and fully depress the accelerator pedal from idle to full stop three times.
What are symptoms of a failing sensor?
Symptoms include erratic idling, surging, lack of power, or the vehicle entering “limp home” mode.
What connector does it use?
The sensor uses an integral Metri-Pack 150 6-pin connector for a plug-and-play watertight interface.
