Walker Engine Coolant Temperature Sensor 15-19 Ford 6.7L Powerstroke

Need to fix inaccurate temp readings, poor cold starts, or a check engine light on your 6.7L Powerstroke? The Walker Engine Coolant Temperature (ECT) Sensor is a direct-fit replacement designed to restore accurate coolant temperature sensor data when your factory unit starts to fail or lose accuracy. The ECT sensor plays a key role in engine management. When it sends incorrect readings, it can throw off fuel delivery, timing, fan operation, and overall performance. This sensor restores the critical temperature signal so your ECU can properly adjust fueling and cooling strategy, keeping your truck running smoothly, efficiently, and reliably. Built to OE fit, form, and function standards, the Walker ECT sensor uses high-quality internal components engineered to deliver precise temperature readings under constant heat cycling and engine load. The design is made to handle common failure causes like moisture intrusion, corrosion, and long-term wear that can lead to erratic signals over time. The housing is built for durability in harsh cooling-system environments, and each unit is fully tested to ensure accurate signal output and reliable ECU communication, resulting in consistent engine performance and long-term reliability.
