Standard Ignition TH240 Throttle Position Sensor

SKU CH-85WJ-CA2EN

A throttle position sensor monitors engine throttle angle for precise fuel management

  • Precise throttle response from Standard Ignition engineering
  • Direct manufacturer shipment ensures authentic component quality
  • Free shipping on orders over $75 adds value
  • New condition guarantees reliable out-of-box performance
  • TH240 model designed for engine and chassis systems

Vehicle Fit & Purpose

The Standard Ignition TH240 is a throttle position sensor designed for engine management systems in recreational vehicles. It monitors throttle valve angle and sends voltage signals to the electronic control unit for precise fuel delivery and ignition timing. This replacement part suits owners and technicians servicing compatible RV powertrains.

Signal Specification

The sensor outputs a variable voltage signal proportional to throttle opening, allowing the ECU to calculate engine load and adjust injector pulse width accordingly. Correct voltage sweep and resistance values are the single specification that determines whether this unit will function properly in a given application.

Capacity & Limits

The TH240 handles the full range of throttle movement from idle to wide-open positions within its calibrated voltage window. It runs out of headroom if the mounting geometry or connector pin-out differs from the original equipment design, or if the ECU expects a different signal characteristic than this sensor provides.

Questions about this item

How does the TH240 sensor translate throttle movement once it is installed in the engine?

The TH240 converts throttle valve position into a voltage signal the engine control module uses to adjust fuel delivery and ignition timing.

What electrical connector standard does the TH240 use and what does that limit?

The sensor uses its original equipment connector, which limits installation to vehicles wired for that specific plug.

What physical mounting points does the TH240 require to fit the throttle body?

The TH240 mounts directly to the throttle body using the factory screw pattern and alignment tab.
