Description
Genuine Mazda 2-Pin Water Temperature Sensor (to ECU) as found in late 1980’s and early 1990’s Mazda engines.
This is the engine coolant temperature (ECT) sensor that the ECU uses to make adjustments to fuelling and ignition as the engine coolant temperature changes. Note that this is NOT the sender that is connected to the water temp gauge on the dashboard.
