Name: Coolant Temperature Sensor Subaru Forester SG SH SJ 22630-AA140 EJ205 EJ25 FB20 FB25
Brand: Aftermarket OEM Replacement
SKU: CCS90-Forester
Price: 59.99 AUD
Availability: InStock

BRAND NEW Aftermarket OEM Replacement coolant temperature sensor to suit Subaru Forester SG (2002-2008), SH (2008-2013) and SJ (2012-2018) across petrol and diesel engine variants.

Forester running rich, idling rough when cold or throwing a coolant temp fault code? The ECT sensor is a common fail item on SG through SJ Foresters - heat cycling and age cause the NTC resistance to drift before the sensor fails outright. This is a direct plug-and-play replacement with oval 2-pin connector and brown housing. Same-day dispatch from Cranbourne VIC.

TO SUIT

Suits Subaru Forester SG5 S Turbo 2.0L EJ205 (2002-2008), SG9 2.5L EJ255 (2005-2008), SH9 2.5L EJ25 126kW (2009-2013), SH9 2.5L EJ255 169kW/193kW (from 02/2011), SHD/SHH/SHN Diesel 2.0L EE20Z (2008-2013), SHM 2.5L FB25 (2011-2013), SJ5 i 2.0L FB20 (2013-2018), SJ9 2.5L FB25 (2012-2018), SJD Diesel 2.0L EE20Z (2013-2018), SJG XT 2.0L FA20 177kW (2013-2018).

FITMENT CHECK

This sensor has an oval 2-pin connector and a brown housing. If your sensor has a D-shaped connector and a black housing the correct part is CTS2035 (OEM 22630-AA230). Both numbers appear in Forester catalogues but they are different connectors and not interchangeable - check your existing sensor before ordering.

ABOUT THIS SENSOR

The ECT sensor on Subaru Forester EJ and FB engines is screwed into the cylinder head or coolant gallery and continuously reports coolant temperature to the ECU. It is one of the most influential inputs in the engine management system - used for fuel injection, ignition timing, idle control, fan operation and cold-start enrichment.

On high-mileage SG and SH Foresters the sensor can develop slowly drifting resistance, causing symptoms that come and go rather than a hard failure. A scan tool showing a coolant temperature that doesn't match ambient on a cold start, or slow warm-up on the gauge, often points to this sensor before a fault code is even stored.

COMMON SYMPTOMS OF FAILURE

Rich running or noticeably higher fuel consumption
Rough or lumpy idle especially when cold
Temperature gauge reading low or not moving
Cooling fan running at start-up or not activating at temperature
Hard cold start or extended cranking
Check engine light - 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.
