Walker Air Charge Temperature Sensor 20-24 Ford 6.7L Powerstroke

Need to fix poor throttle response, low power, or a check engine light caused by bad intake air temperature readings? The Walker Air Charge Temperature (ACT) Sensor is a direct-fit replacement that restores accurate air charge temperature sensor data on 6.7L Powerstroke engines. The ACT sensor plays a critical role in engine management by measuring the temperature and density of incoming air, enabling the ECU to adjust fueling and performance properly. When it fails, you may notice reduced power, poor fuel economy, a rough idle, or stalling. This sensor restores that key signal so your truck runs clean, responsive, and properly fueled again. Built to OE fit, form, and function standards, the Walker ACT sensor uses high-quality internal components engineered to deliver precise temperature readings under constant exposure to heat, vibration, and airflow. The design is intended to withstand common failure modes such as moisture intrusion, oil contamination, and carbon buildup, which can lead to inaccurate readings over time. The durable housing is built for long-term reliability in harsh intake system environments, and each unit is tested to ensure accurate signal output and consistent ECU communication for dependable performance and long service life.
