BRAND NEW Aftermarket OEM Replacement coolant temperature sensor to suit a wide range of Subaru vehicles including Forester SH/SJ, Impreza, Liberty, Outback, BRZ, Levorg, Tribeca and XV.

If your Subaru is running rich, idling erratically, taking longer to warm up than usual, or throwing a coolant temperature fault code - the ECT sensor is one of the first things to check. This is a direct-fit replacement with the correct M12x1.5 thread, D-shaped 2-pin connector and black housing. Dispatched same-day from Cranbourne VIC.

TO SUIT

This sensor suits Subaru BRZ Z1 (2012-2022) FA20D, Forester SH (2008-2013) EJ25/EJ255/EE20Z and SJ (2013-2019) FB20/FB25/FA20/EE20Z, Impreza GE/GH/GR/G3 (2007-2013) EJ204/EJ255/EJ257, GJ/GJ7 (2011-2016) FB20B, GP/GP7 (2012-2016) FB20, GR/GE7/GVE/GVF (2008-2016) EJ204/EJ255/EJ257, Levorg EK V1 (2015-2021) FB16, Liberty BL/BL5/BL9/BLE (2003-2009) EJ202/EJ204/EJ25/EZ30, BM/BM9/BMF (2009-2014) EJ253/EJ255/EZ36D, BN/BN9 (2015-2021) FB25, BP/BP5/BP9/BPE (2003-2009) EJ202/EJ204/EJ25/EZ30, BR/BR9/BRM (2009-2014) EJ253/EJ255/FB25, Outback BP/BPE (2003-2009), BR/BRD/BRF/BRM (2009-2015), BS/BS9/BSD/BSF (2014-2021), Tribeca WXE/WXF (2006-2013) EZ30/EZ36D, and XV GP7/GPE (2011-2023) FB20B/FB20. See compatibility list for full date ranges and engine codes.

FITMENT CHECK - IMPORTANT

Two different coolant temperature sensors suit some of the same Subaru vehicles. Before ordering confirm your sensor has a D-shaped (not oval) connector and a black housing. If your existing sensor has a brown housing with an oval connector the correct replacement is CCS90 (Suzuki OEM 13650-73H00) not this part. Mixing these two sensors is the most common ordering error on these vehicles - the connector will not fit if the wrong part is selected.

ABOUT THIS SENSOR

The engine coolant temperature (ECT) sensor is a thermistor screwed into the engine block or coolant passage that reports coolant temperature to the ECU in real time. The ECU uses this signal to adjust fuel injection duration, ignition timing, idle speed, and fan operation - it is one of the most referenced inputs in the engine management system.

On Subaru FA, FB, EJ and EZ engines a failing ECT sensor typically causes rich running during warm-up, poor fuel consumption, rough idle, or fan operation faults. NTC sensors fail gradually - resistance drifts before the sensor fails completely, making the symptoms intermittent and hard to diagnose without live data.

COMMON SYMPTOMS OF FAILURE

Engine runs rich or uses more fuel than normal
Rough idle or idle that hunts when cold
Long warm-up time or temperature gauge reading incorrectly
Cooling fan running constantly or not at all
Hard start in cold conditions
Check engine light - fault codes P0115 P0116 P0117 P0118 P0119

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.
