PACKAGE INCLUDES:

1 X OEM Quality ENGINE COOLANT TEMPERATURE SENSOR (3-PIN PLUG).

The Engine Coolant Temperature Sensor, often called 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, and other engine parameters to ensure optimal performance, fuel efficiency, and 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, or problems with starting the engine. A failing sensor might cause the engine to run too rich or too lean, impacting fuel efficiency and potentially causing damage to the engine over time.

COMMON QUESTIONS

Where is this sensor located?
Usually found on the thermostat housing or the engine block near the coolant outlet.

Will this fix my temperature gauge?
Yes if your gauge is fluctuating or reading zero this sensor is often the culprit.

Does it come with a seal?
Yes a new high-temperature seal ring is included.

How do I test a coolant temperature sensor?

The most common test is to measure the sensor resistance with a multimeter at a known coolant temperature and compare against the manufacturer resistance curve. A cold engine (20 degrees C) typically reads 2,000 to 3,000 ohms and drops to around 200 to 300 ohms at operating temperature (90 degrees C). An OBD2 scanner showing a fixed temperature reading that does not change as the engine warms up is also a strong indicator of sensor failure.

Can a faulty coolant temperature sensor cause my engine to overheat?

Indirectly yes. If the sensor reports a lower temperature than actual, the ECU may not activate the cooling fan at the correct time, allowing the engine to overheat. It can also suppress the dashboard warning light, meaning you may not be alerted until the engine is already at a dangerously high temperature. Replace a suspected faulty sensor promptly.

Do I need to drain the coolant to replace the sensor?

Not always - many coolant temperature sensors can be replaced quickly with minimal coolant loss if you work fast and have a replacement ready to thread in immediately. However on some vehicles the sensor location requires partial coolant drainage. Check the sensor position on your specific engine before starting. Always use fresh coolant when topping up after replacement.

What are the symptoms of a faulty coolant temperature sensor?

Symptoms include poor fuel economy, black smoke, engine overheating warning, incorrect temperature gauge reading, hard starting when cold, and rough idle. Fault codes P0115 to P0119 are commonly associated with coolant temperature sensor faults.

Is it safe to drive with a bad coolant temperature sensor?

A faulty coolant temperature sensor can cause the ECU to run rich fuel mixtures and prevent the cooling fan from operating correctly, risking engine overheating. Replace it promptly - it is a low-cost part that can prevent expensive engine damage.

How do I know if my coolant temperature sensor or my thermostat is faulty?

A faulty thermostat typically causes the engine to overheat or never reach operating temperature. A faulty coolant temp sensor causes incorrect gauge readings and running issues but the coolant itself may be at the correct temperature. An OBD2 scanner showing live coolant temp data helps distinguish between the two.

Are there two coolant temperature sensors on my vehicle?

Many vehicles have two sensors - one for the ECU (engine management) and one for the dashboard temperature gauge. They look similar but are not interchangeable. Check your vehicle's service manual or contact us with your vehicle details to confirm which sensor you need.
