BRAND NEW *OEM Quality* cylinder head temperature sensor to suit Ford Focus LS LT LV 2.0L Duratec / Escape BA ZA ZB ZC ZD 2.3L / Mondeo HA HB HC HD HE MA MB MC 2.0L 2.3L.

Check engine light on with a P1288 or P1289 code, or your Focus fans are running constantly at high speed? The CHT sensor on the 2.0L and 2.3L Duratec fails gradually and triggers the same fail-safe cooling response as on larger Ford engines. This is the direct-fit M10 replacement. Same-day dispatch from Melbourne.

TO SUIT

Suits Ford Focus LS / LT / LV with the 2.0L AODB / AODE Duratec engine (2005-2011), Escape BA / ZA / ZB / ZC / ZD with the 2.3L L3 engine (2004-2013), and Mondeo HA through HE with the 2.0L NGA-NGD engine (1996-2001) and MA / MB / MC with the 2.3L SEBA (2007-2014). M10x1.5 thread - 2-pin clip connector.

PACKAGE INCLUDES

1 x cylinder head temperature sensor. M10x1.5 thread. 2-pin clip connector. 19mm spanner. Direct plug-in replacement - no wiring modification required.

ABOUT THIS SENSOR

The cylinder head temperature (CHT) sensor threads into a dry port in the cylinder head and measures actual metal temperature rather than coolant temperature. Ford uses this on the Duratec 2.0L and 2.3L to feed the PCM real-time overtemperature data. If the reading exceeds safe limits the ECU activates fail-safe cooling - fans at maximum, reduced power - to protect the engine from heat damage even with coolant loss.

When the sensor fails it typically reads permanently high, locking the engine into fail-safe mode continuously. Replacing the sensor clears the condition immediately without further programming.

COMMON SYMPTOMS OF FAILURE

Cooling fans running at full speed constantly even when engine is cold
Limp mode or reduced power with no genuine overheating event
Temperature gauge reading falsely high or spiking erratically
Check engine light with codes P1288 / P1289 / P1290 / P1299
Increased fuel consumption
Rough idle or hesitation under light load

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.
