Product Features
williams 131040
High-Precision Signal Output
The 131040 sensor utilizes premium potentiometric technology to deliver a smooth, linear voltage signal to the Engine Control Unit (ECU). This ensures accurate throttle mapping and eliminates “dead spots” often found in worn mechanical sensors.
Rugged Environmental Sealing
Designed for floor-mounted or firewall applications, the unit features robust sealing to protect internal components from dust, dirt, and moisture. This IP-rated protection ensures long service life even in severe weather conditions.
FMVSS-124 Compliance
Safety is paramount in heavy-duty applications. This sensor is engineered to meet or exceed FMVSS-124 safety standards, ensuring that the throttle returns to idle promptly in the event of a mechanical failure or linkage disconnection.
Applications
131040 tps
- Commercial Heavy-Duty Trucks: Replacement sensor for International 4000/8000 series and Volvo Class 8 trucks.
- Engine Retrofits: Critical interface for pre-1998 Cummins engines requiring electronic throttle control.
- Transit & School Buses: Ensures safe operation and reliable acceleration for fleet passenger vehicles.
- Construction Machinery: Durable sensing for excavators and loaders operating in high-vibration environments.
- Utility Vehicles: Used in refuse trucks and fire apparatus where component reliability is non-negotiable.

FAQ
international 133313
What engines are compatible with the tps 131040?
The tps sensor 131040 is commonly used with Cummins, Detroit Diesel, and Mercedes engines found in International and Volvo chassis. Always verify the part number on your existing unit before ordering.
Is the 131040 interchangeable with other Williams part numbers?
when a 133313 sensor go bad? Common signs include erratic engine idling, lack of throttle response, “dead spots” during acceleration, or an active Check Engine Light with TPS-related error codes. See more about Throttle Position Sensor Symptoms
Is the 131040 interchangeable with other Williams part numbers?
While it looks similar to other sensors, the 131040 has specific resistance and output curves. It is generally not interchangeable with parts like 131973 unless specified by a cross-reference list.
How do I test the 131040 sensor?
You can test the sensor using a multimeter. Measure the resistance across the signal pins while actuating the pedal; it should change smoothly without open circuits. Ensure the 5V reference voltage is present from the harness.
Does this sensor kit include the wiring harness?
Some versions of the williams 131040 are sold as a kit including a short wire harness and mounting screws, while others are sensor-only. Check the specific product listing details of williams controls.
