GPD 1812953 Flex Fuel Sensor E85 Ethanol Content Sensor

The GPD 1812953 Flex Fuel Sensor is a direct-fit replacement sensor designed for vehicles equipped with flex fuel capability. This sensor monitors and regulates the ethanol-gasoline ratio in the fuel system, allowing the engine control module (ECM) to make precise adjustments for optimal performance whether running on regular gasoline, E85, or any blend in between.

Key Features:

• Designed to meet or exceed OE fit, form, and function specifications
• Direct replacement sensor for flex fuel equipped vehicles
• Sends accurate ethanol content data to the ECM for proper fuel mixture adjustments
• Typically mounted on the fuel line between the tank and engine
• Engineered for reliable performance with E85 and gasoline blends
• Backed by GPD's one-year warranty against defects in materials and workmanship

Why It Matters:

A malfunctioning flex fuel sensor can cause hard starting, rough idle, decreased engine power, stalling, engine shutdown, and failed emissions tests. The sensor plays a critical role in the fuel management system by determining the exact ethanol content of the fuel, which requires different air-fuel ratios and ignition timing compared to standard gasoline. Replacing a faulty flex fuel sensor restores proper engine performance and fuel economy.

GPD (Global Parts Distributors) has been a trusted name in automotive aftermarket parts since 1974, delivering quality engine management sensors that provide accurate data to vehicle control systems.
