Denso Coolant Temperature Sensors

Part of the engine management system, Denso coolant temperature sensors detect the temperature of the engine coolant. These sensors are located on the engine or in one of the coolant passages in a cylinder head.

Features and benefits of Denso coolant temperature sensors include:

* Provides the ECU with vital information to help control fuel injection, ignition timing, and transmission shifting
* A failing sensor can cause the engine to run rich or lean, cause the transmission to shift incorrectly, or cause the Check Engine Light to illuminate
