Subaru WRX Engine Coolant Temperature Sensor
$20.99
The engine coolant temperature sensor tells the ECU how hot the engine is running, which affects fuel mixture, cooling fan operation, and idle behavior. A bad CTS can cause poor cold starts, overheating fans that never kick on, or an inaccurate temperature gauge.
This sensor is built for the Subaru WRX 2.0L Turbo FA20 engine and threads directly into the factory coolant passage location.
Made to OEM specifications for accurate resistance readings across the full temperature range, it's an affordable way to keep your cooling and fueling systems talking correctly.
