Replace the faulty air charge temp sensor in your 1991-1996 Dodge 5.9L Diesel with a Walker 210-91015 Air Charge Temperature (ACT) Sensor With Pigtail from XDP. The air charge temperature sensor is used by the PCM to determine the temperature and density of air entering the engine. The PCM then uses this information to determine fuel injector control and other outputs. The ACT sensor is often found in the air intake boot, in the air cleaner housing, or intake manifold. These sensors can eventually fail due to simple wear and tear. The sensor connector and wiring harness can also lose connectivity over time. Exposure to excessive moisture can erode the sensor internally, causing erratic readings. The accumulation of oil and carbon can also cause failure. Common symptoms that your temperature sensor has failed can include poor fuel economy, reduced engine power, a rough idle, surging/stalling or a check engine light.

The repetition of extreme heat and cold, known as "heat cycling", breaks down internal circuitry in the sensor but also deteriorates the connector and harness. Other contaminants such as oil and road debris can also lead to connector and harness failures. When installing a Walker Products replacement sensor the factory mating connector and harness might also be inadvertently get damaged during the process as the plastic tabs often get brittle. A Walker Products full service kit offers a complete repair solution. The full-service kit contains not only the base sensor, but also provides the mating connector, pigtail, butt splices, and heat-shrink to ensure a watertight connection. Walker Products sensors are engineered using high-quality components and materials to ensure proper fit and response. Walker Temperature Sensors are 100% tested for peak performance and worry-free operation.
