BRAND NEW *OEM Quality* coolant temperature sensor to suit Hyundai i20, Getz, Coupe, i45, Santa Fe, Sonata, Tucson, Terracan and Trajet models.

A failing coolant temperature sensor sends the wrong signal to the ECU across this whole Hyundai range, causing hard starting, poor fuel economy and an illuminated check engine light. This aftermarket OEM quality replacement restores accurate readings. Same-day dispatch before 12pm from Cranbourne VIC.

ABOUT THIS SENSOR

This one sensor covers a wide cross-section of Hyundai's mid-2000s to late-2010s petrol, V6 and CRDi diesel range, all sharing the same coolant temperature sensor and connector.

A failed sensor here reads out-of-range temperature to the ECU, which can richen or lean the fuel mixture, upset cooling fan cycling and, over time, contribute to overheating going undetected on the dash gauge.

COMMON SYMPTOMS OF FAILURE

Check Engine Light illuminated with fault codes P0115-P0119
Poor fuel economy from an incorrect air-fuel mixture
Difficult cold starting or rough idle
Engine running noticeably rich or lean
Erratic or inaccurate temperature gauge reading
Cooling fan running constantly or not engaging

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.
