    Walker Products 243-1001 flex fuel sensor for the 2002-2005 Chevrolet Silverado 1500 V8 5.3L and other vehicles monitors the ethanol content of blended fuel. The engine control module uses that reading to adjust fuel delivery and ignition timing.

    • Reads blended fuels from E0 to E85 and beyond
    • Sends real-time ethanol percentage data to the engine control module
    • 3/8" quick-connect fittings for factory or custom fuel lines
    • Resists fuel, temperature swings and corrosion

    Quick facts

    • Part: Walker Products 243-1001 flex fuel sensor
    • Fits: 2002-2005 Chevrolet Silverado 1500 V8 5.3L and other vehicles

    A warning light, poor fuel economy or rough running can mean the flex fuel sensor is reading ethanol content wrongly. Before you replace the sensor, rule out damaged wiring or a loose connector first. If a failed sensor is the cause, this one takes its place.

    This direct-fit replacement flex fuel sensor suits the 2002-2005 Chevrolet Silverado 1500 V8 5.3L, the 2002-2005 GMC Sierra 1500 V8 5.3L and the 2002-2005 Chevrolet Tahoe V8 5.3L, among other vehicles, and each takes one.
