Product Description

The Fuel Composition Sensor is a component used in some modern vehicles to measure the composition of the fuel being used in the engine. It is typically located in the fuel tank or fuel lines and works by using a combination of sensors and algorithms to analyze the fuel.

The Fuel Composition Sensor can detect the presence of ethanol, methanol, and other fuel additives, as well as water and other contaminants that can affect engine performance and emissions. This information is sent to the engine control module (ECM), which adjusts the fuel injection and ignition timing to optimize engine performance and reduce emissions.

In addition, the Fuel Composition Sensor can also detect fuel quality issues such as low octane rating, which can cause engine knocking and damage. If the Fuel Composition Sensor detects a problem with the fuel, it may trigger a warning light or message on the dashboard, indicating that the fuel needs to be checked or replaced.

Daysyore offers Oil Level Sensor products to improve fuel economy, boost power, and reduce emissions issues.
