FAQ
Detailed Electromechanical Parameters
What is the primary advantage of the 132431W1L over the 134169 model?
The 132431W1L utilizes non-contact Hall Effect technology, which provides a virtually infinite mechanical life and better resistance to dither wear compared to older contact-based versions like the Throttle Position Sensor 134169 Williams variants.
Is the WCS 132431W1L interchangeable with WCS-134221W1L?
While they share similar mounting footprints, you must verify the output voltage slope and connector pinout, as different suffixes denote specific calibration curves required by different ECM manufacturers.
How do I calibrate the idle and full-throttle voltage?
The sensor is factory-calibrated; however, most industrial ECMs require a “throttle relearn” procedure via diagnostic software to sync the 0% and 100% duty cycles after installation.
What is the environmental sealing rating?
The unit is typically rated at IP67, meaning it is fully protected against dust ingress and can withstand temporary immersion in water, making it ideal for exposed chassis mounting.
Can this sensor be used in 24V systems?
The sensor itself typically operates on a regulated 5V reference from the ECU. Direct connection to 24V battery power will result in immediate component failure.
