BRAND NEW *OEM Quality* coolant temperature sensor to suit Hyundai Sonata Santa Fe Grandeur Lantra and Excel models.

This 2-pin sensor design was used across several Hyundai generations spanning more than two decades, so cross-check your OEM number against the list below before ordering. Independently verified against TecDoc catalogue. Shipped via Australia Post Express from Victoria.

TO SUIT

Covers the Hyundai Sonata Y-2/Y-3/NF/LF, Santa Fe CM/DM/TM, Grandeur TG, Lantra J-1/J-2, Excel X-3, Coupe RD and S Coupe, across four-cylinder, V6 and diesel engine variants from 1990 through to recent Santa Fe generations. Full year-by-year coverage is listed in the vehicle compatibility section below.

FITMENT CHECK

This is the 2-pin coolant temperature sensor. Some Hyundai models across these generations also used a 3-pin sensor variant - count the pins on your original sensor's plug before ordering to make sure this is the correct connector for your vehicle.

ABOUT THIS SENSOR

On the later Santa Fe CRDi diesel variants (D4HB) this signal feeds glow-plug and EGR strategy in addition to fan control, so a fault tends to show as harder cold starts alongside the usual overheating symptoms.

On the earlier Sonata and Lantra petrol models the more common symptom is a rich or lean idle and a fan that won't cut in, since there's no diesel-specific control to complicate the picture.

COMMON SYMPTOMS OF FAILURE

Poor cold-start fuel enrichment or hard starting from cold
Check Engine Light with DTC P0116, P0117 or P0118
Engine running rich or lean and reduced fuel economy
Cooling fan running constantly or not switching on
Harder cold starts on Santa Fe CRDi diesel models

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.
