FAQ
international 133313
Is the 133313 TPS compatible with all Williams Controls pedals?
The 133313 TPS is designed for specific Williams Controls pedal assemblies commonly used in Volvo, Freightliner, and Kenworth trucks. Always verify the part number stamped on your existing sensor before replacement.
What are the symptoms of a failing 133313 sensor?
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
Does this sensor require calibration after installation?
Generally, the 133313 williams controls is plug-and-play for supported ECUs. However, some engine management systems may require a key-cycle calibration or a “learn” procedure to recognize the new voltage limits. See here to learn more about Throttle Position Sensor Calibration
Can I use a multimeter to test the williams controls133313 TPS
Yes. You can back-probe the connector to verify the 5V reference voltage and check that the signal wire voltage changes smoothly from approximately 0.5V (idle) to 4.5V (wide open throttle) without dropouts.
