PACKAGE INCLUDES:

1 X *OEM QUALITY* ENGINE COOLANT TEMPERATURE SENSOR (4-PIN SQUARE PLUG).

The engine coolant temperature sensor, often abbreviated as ECT sensor or CTS (Coolant Temperature Sensor), is a crucial component in a vehicle's engine management system.

It measures the temperature of the engine coolant and sends this information to the engine control unit (ECU) or the powertrain control module (PCM).

This data helps the ECU adjust:

• Fuel injection
• Ignition timing
• Other engine parameters

Ensures:

• Optimal performance
• Fuel efficiency
• Emission control

If the coolant temperature sensor malfunctions or fails, it can lead to issues such as:

• Incorrect fuel mixture
• Poor engine performance
• Increased emissions
• Problems with starting the engine

A failing sensor might cause the engine to:

• Run too rich or too lean
• Impact fuel efficiency
• potentially cause damage to the engine over time
