Product Features
williams controls 134030
Dual APS Signal Output
The 134030 sensor provides two independent analog voltage signals (APS1/APS2). This redundancy allows the Engine Control Unit (ECU) to cross-check throttle position data, ensuring fail-safe operation and preventing unintended acceleration events.
IP67 Environmental Protection
Designed for floor-mounted pedals exposed to the elements, the unit features advanced sealing to resist water intrusion, road salt, and dust. This ensures the will 134030 maintains signal integrity even in severe weather conditions.
Complete Replacement Kit
Unlike standalone sensors, the williams controls 134030 is typically supplied as a comprehensive kit. It includes the sensor module, necessary mounting hardware, and often a wiring adapter, streamlining the retrofit process for technicians.

FAQ
williams controls 134030
Is this sensor interchangeable with the 133313 TPS?
No, they are different parts. While both are made by Williams Controls, the 133313 TPS and 134030 have different output calibrations and connector configurations. Always install the specific part number required by your ECU.
Does the 134030 kit come with a harness?
Yes, the 134030 is often sold as a service kit that includes the sensor module and a short jumper harness or mounting bolts to facilitate installation on existing pedal assemblies.
How do I troubleshoot a 134030 sensor fault?
Check for 5V reference voltage at the connector and verify the ground. Using a multimeter or scan tool, observe the APS1 and APS2 voltages; they should move linearly without dropouts as the pedal is depressed.
What are the signs of failure for this sensor?
Symptoms include a Check Engine Light, “Limp Mode” (reduced power), or lack of throttle response. The ECU will often set specific voltage correlation codes if the 134030 signal drifts out of range.
