Walker Products 210-1146 Engine Intake Manifold Temperature Sensor

Walker Products Engine Intake Manifold Temperature Sensors are precision-engineered OE Replacement components that measure the temperature of incoming air entering the engine’s intake system. This data is critical for the engine control unit (ECU) to calculate air density, optimize fuel injection, adjust ignition timing, and manage emissions output. Unlike external air temp sensors, these sensors operate inside the intake manifold or air tract—providing a more accurate measurement of actual combustion air temperature under load. Over time, intake manifold temperature sensors can degrade, causing incorrect temperature readings that result in rich/lean fuel trims, drivability issues, hesitation, or emissions faults. Walker sensors are manufactured to meet or exceed OE specifications for resistance curves, temperature range, and electrical response. Built from durable, heat- and oil-resistant materials, they are designed to endure thermal cycling and exposure to oil vapor, fuel mist, and engine heat. Each unit is engineered for an exact OE fit and installs directly into the factory manifold, throttle body, or intake duct using the original mounting point and wiring connector. Whether replacing a failed sensor or correcting a check engine light, Walker Intake Manifold Temperature Sensors restore precise air-temp monitoring for improved combustion efficiency, drivability, and emissions performance.
