Standard Motor Products Flex Fuel Sensor

The Standard Motor Products Flex Fuel Sensor (also called an ethanol content sensor or fuel composition sensor) measures the ethanol percentage in the fuel flowing through the fuel system. It sends that data to the engine control module, which uses it to adjust fuel delivery and ignition timing for the fuel blend in the tank.

Key Features:

• Monitors ethanol content and fuel temperature in flex fuel systems
• Gives the engine computer the data it needs to adjust the air/fuel mixture and spark timing
• Helps maintain drivability, fuel efficiency, and emissions performance on gasoline/ethanol blends
• Designed to match the form, fit, and function of the original equipment sensor
• Backed by Standard Motor Products' engineering experience in engine management components

A failing flex fuel sensor can cause a check engine light, rough running, hard starting, or poor fuel economy. Replacing it restores accurate fuel composition readings and proper engine management. Each individual part number in this line is specific to its application, so choose the correct variant for your vehicle.
