Review SKI DOO Oem Tps Throttle Position Sensor fits SUMMIT 2005–2017

The Ski-Doo 404162079 Throttle Position Sensor (TPS) is a crucial component in the fuel injection system of Summit 800R snowmobiles manufactured between 2005 and 2017. This sensor is responsible for measuring the position of the throttle assembly and transmitting that information to the engine control module (ECM), enabling the precise delivery of fuel to the engine based on the rider's input.

The TPS is a compact, electronic component designed to provide reliable and accurate readings in various operating conditions. It is mounted on the left side of the snowmobile's engine, near the throttle assembly. The sensor contains an internal potentiometer that generates a voltage output proportional to the throttle position.

When the rider opens the throttle, the TPS sends a signal to the ECM, which then calculates the appropriate fuel injection duration and pressure based on the engine's RPM and temperature. A faulty TPS can lead to poor engine performance, erratic idling, and difficulty starting the snowmobile.

This TPS is a direct replacement for the original equipment and comes with a plug-and-play wiring harness, making the installation process straightforward. The sensor is engineered to withstand the harsh conditions of snowmobiling, ensuring durability and longevity.

When it comes to maintaining optimal performance and ensuring a safe and enjoyable riding experience, a properly functioning TPS is essential. If you suspect that your Summit 800R's TPS is faulty, consider replacing it with this high-quality aftermarket option from Ski-Doo.

The Ski-Doo Summit 800R TPS Throttle Position Sensor (Part Number: 404162079) is an essential component of the fuel injection system in Ski-Doo Summit 800R snowmobiles manufactured between 2005 and 2017.

Ultimately, replacing the sensor is a cost-effective and relatively simple solution that can help restore optimal engine performance in your Ski-Doo Summit 800R snowmobile.
