Walker Products Engine Coolant Temperature Sensor - ECT Sensor OE Replacement

The Walker Products Engine Coolant Temperature (ECT) Sensor is an OE replacement sensor. It monitors engine coolant temperature and sends that data to the engine control module (ECM/PCM). The ECM uses the signal to help manage fuel delivery, ignition timing, idle speed, cooling fan operation and emissions control. It is also known as a coolant temp sensor or water temperature sensor.

Key Features:

• Designed as a direct replacement for the original equipment sensor
• Sends accurate coolant temperature readings to the engine computer
• Helps support smooth starting, stable idle and efficient fuel management
• Helps the engine run at the correct operating temperature
• Built by Walker Products, a long-established name in engine management and emissions components

Signs of a Failing Sensor:

• Check engine light
• Hard starting or rough idle
• Poor fuel economy
• Black smoke from the exhaust
• Cooling fan that runs constantly or not at all

Replacing a worn or faulty coolant temperature sensor helps restore proper engine performance, drivability and emissions control.
