Walker 210-1146 Air Charge Temperature Sensor

Walker Air Charge Temperature Sensor 210-1146

Walker Sensor Only 210-1146 is an OE-style air charge temperature sensor for intake manifold temperature monitoring. It measures incoming air temperature inside the intake tract so the ECU can calculate air density, adjust fuel delivery, and manage ignition timing and emissions control.

Key Features

• Air charge temperature sensor for intake manifold or intake duct applications
• Sensor Only line focused on direct replacement fitment
• 2-pin design with female connector, male terminals, and oblong connector shape
• Built with heat- and oil-resistant materials for engine-bay exposure
• Engineered to meet or exceed OE resistance curve, temperature range, and electrical response
• Direct-fit replacement for Dodge Ram 2500 and Dodge Ram 3500 applications

Product Details

Walker 210-1146 is designed for vehicles that rely on accurate intake air temperature data to maintain proper combustion control. By reading the temperature of air entering the engine’s intake system, this sensor helps the ECU make precise adjustments that affect drivability, fuel trim, and emissions output. The Sensor Only product line is built for direct replacement use where the original sensor is the service part needed.

This part cross-references Gates AX68 for the same application. It is also listed with interchange reference 5011402AA and Karlyn 5097.

Compatible With 1998-2002 Dodge Ram 2500 and 1998-2002 Dodge Ram 3500, sensor only applications. The Walker 210-1146 is a direct-fit option for these Dodge Ram models when replacing the intake manifold temperature sensor.

Common Issues This Sensor Can Address

• Incorrect intake air temperature readings
• Rich or lean fuel trim conditions
• Hesitation during acceleration
• Check engine light related to intake air temperature sensing
• Emissions faults tied to inaccurate sensor input

Installation Notes

Install the sensor at the original manifold, throttle body, or intake duct mounting point using the factory connector. Verify connector shape, terminal count, and sensor location before installation. For best results, inspect the wiring harness and connector terminals for corrosion, heat damage, or looseness before replacing the sensor.

Quality Assurance

Walker manufactures this sensor to OE-style specifications for fit, resistance characteristics, and electrical response. The design uses durable materials selected for thermal cycling and exposure to oil vapor, fuel mist, and engine heat.
