1. 134030 Throttle Position Sensor Fit for International & Williams & Mack Auto Parts Throttle Position Sensor Replaces 134734 134143 1697269C91 1697269C92

Buyers frequently appreciate the ability to use this single part number across different engine brands.
The wide compatibility list helps reduce the time spent searching for niche components.

Choosing Between Them
I recommend the Williams Controls 131973 as your primary choice for any serious maintenance project. For those managing a diverse fleet, the 134030 Multi-Brand Sensor provides necessary flexibility, while the 133284 Budget-Friendly Sensor remains the go-to for low-cost repairs. My top pick is the Williams Controls 131973 because I value the reliability that comes with using a genuine part.
Always verify your engine serial number before finalizing your purchase, as even minor production updates can change fitment requirements. While aftermarket options provide a functional alternative, using the correct factory-specified sensor ensures your throttle response remains sharp and predictable. Choosing the right component today will likely save you from an unexpected headache on the road later.
