89422-33030 ENGINE COOLANT TEMPERATURE SENSOR FOR TOYOTA CAMRY COROLLA RAV4 PRIUS LEXUS

This engine coolant temperature sensor is a direct replacement for OEM part number 89422-33030. It monitors the temperature of the engine coolant and sends this signal to the engine control unit, which uses the data to manage fuel injection, ignition timing, and cooling fan operation. Manufactured to OEM specifications, this 2-pin sensor with M12x1.5 thread is designed for a wide range of Toyota, Lexus, and Scion vehicles. Cross-reference numbers include DENSO 193-1000, Standard TX109, and BWD WT5123. Note: this is a coolant temperature sensor, not an oxygen sensor, MAF sensor, or brake pad wear sensor.
