Coolant Temperature Sensor for Ford Ranger PX Focus LW Escape ZC ZD 8E5A12A648AA

BRAND NEW *OEM Quality* Coolant Temperature Sensor for Ford Ranger Focus Escape Mondeo petrol engines.

A failing coolant sensor sends the wrong signal to the ECU, causing rough idle, poor fuel economy or a stuck temperature gauge. This direct-fit replacement restores accurate readings and is dispatched same-day from our Cranbourne VIC warehouse.

TO SUIT

Fits a wide range of Ford petrol models including Ranger PX (2.5L), Focus LS-LW (2.0L & 2.5L Turbo), Escape BA-ZD (2.3L), Mondeo HA-MC (2.0L & 2.3L) and Explorer UN-US (4.0L V6). See the full model and engine compatibility list below before ordering.

FITMENT CHECK

Check your connector! This sensor uses a Rectangular 2-Pin Grey Plug. If your original sensor is oval-shaped or has 3 pins, this is not the correct part.

ABOUT THIS SENSOR

The Engine Coolant Temperature Sensor (ECT/CTS) measures coolant temperature and reports it to the ECU, which uses that reading to adjust fuel injection, ignition timing and cooling fan operation.

A failed sensor can cause hard starting, rough idle, an inaccurate temperature gauge, poor fuel economy and increased emissions - and in some cases the engine running permanently in "limp" mode.

COMMON SYMPTOMS OF FAILURE

Temperature gauge reading incorrectly, stuck on cold, or fluctuating
Engine warning light with fault code P0117 or P0118
Rough idle or hesitation, especially on a cold start
Cooling fans running constantly or not engaging at all
Poor fuel economy from an over-rich fuel mixture
Black smoke from the exhaust

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.
