Locating the Coolant Temperature Sensor on Your 2017 Ford Escape
Let’s get down to business. Finding the 2017 Ford Escape temperature sensor location involves a bit of visual searching under the hood. It’s typically found threaded into the engine block or cylinder head, directly in the path of the coolant flow.
The Primary Location: Near the Thermostat Housing
For most 2017 Ford Escape models, the coolant temperature sensor is located on or very near the engine’s thermostat housing. The thermostat housing is usually a metal or plastic component where the upper radiator hose connects to the engine.
When you open the hood and locate the engine, look for the thick hose coming from the radiator that connects to the engine. Follow this hose to where it meets the engine block. You’ll likely find a housing there, often with a thermostat inside. The ECT sensor is typically screwed into this housing or an adjacent coolant passage.
Visual Cues and Identifying the Sensor
The ECT sensor is a relatively small, cylindrical component, usually made of brass or plastic, with an electrical connector plugged into its top. This connector will have wires leading back to the PCM. The sensor itself will have threads on one end, designed to screw into the engine’s cooling system.
Keep an eye out for a sensor that looks different from other sensors in the vicinity, such as the oil pressure sensor or the throttle position sensor. The ECT sensor is specifically in a coolant passage.
Tools You’ll Need for Access and Removal
Before you start, gather the necessary tools. Having them ready will make the process smoother and safer.
- Socket Set and Ratchet: You’ll likely need a specific size socket to remove the sensor. Common sizes are 19mm or 13/16 inch.
- Pliers (Optional): Sometimes, the electrical connector can be a bit stubborn. Needle-nose pliers can help gently release it.
- Torque Wrench (Recommended): For proper installation, a torque wrench ensures the sensor is tightened to the correct specification, preventing leaks.
- Drain Pan and Coolant: If you need to drain some coolant to prevent spills, have a drain pan and fresh coolant ready.
- Shop Rags: For wiping up any spilled coolant.
- Safety Glasses and Gloves: Always protect your eyes and hands.
Step-by-Step: Accessing and Replacing the Sensor
This is where the practical application of knowing the 2017 Ford Escape temperature sensor location comes into play. Follow these steps carefully.
Safety First: Engine Cool and Battery Disconnected
- Ensure the engine is completely cool. Never attempt to work on the cooling system when the engine is hot. Pressurized hot coolant can cause severe burns.
- Disconnect the negative battery terminal. This prevents any accidental electrical shorts while you’re working.
Locating the Sensor and Disconnecting the Connector
- With the engine cool, locate the ECT sensor using the descriptions above.
- Carefully disconnect the electrical connector. There’s usually a tab or clip you need to press to release it. If it’s stuck, gently wiggle it or use pliers designed for electrical connectors, being careful not to damage the wires.
Removing the Old Sensor
- Place your drain pan underneath the sensor to catch any residual coolant.
- Using the appropriate socket and ratchet, carefully loosen and remove the old sensor. Turn it counter-clockwise.
- Once loosened, unscrew it by hand. Be prepared for a small amount of coolant to drip out.
Installing the New Sensor
- Before installing the new sensor, ensure the threads are clean and free of debris.
- Apply a small amount of thread sealant (if recommended by the sensor manufacturer) to the threads of the new sensor. Some sensors have a built-in seal and don’t require sealant.
- Carefully thread the new sensor into the engine block or housing by hand to avoid cross-threading.
- Once hand-tight, use your socket and ratchet to snug it up. If you have a torque wrench, tighten it to the manufacturer’s specified torque value. Overtightening can damage the threads or the sensor.
- Reconnect the electrical connector. You should hear or feel it click into place.
Refilling Coolant and Reconnecting Battery
- If you drained coolant, refill the system to the proper level with the correct type of coolant for your 2017 Ford Escape.
- Reconnect the negative battery terminal.
- Start the engine and let it reach operating temperature. Monitor for any leaks around the sensor.
Common Problems Related to a Faulty Coolant Temperature Sensor
A failing ECT sensor can manifest in several ways, often mimicking other engine issues. Recognizing these symptoms is crucial for proper diagnosis.
Inaccurate Temperature Readings
The most direct symptom is an inaccurate reading on your temperature gauge. It might read too high, too low, or fluctuate erratically. This can lead to the cooling fans not engaging when they should, or staying on unnecessarily.
Poor Fuel Economy
When the PCM receives incorrect temperature data (e.g., thinking the engine is colder than it is), it will often richen the fuel mixture. This results in your Escape consuming more fuel than it should, leading to a noticeable drop in MPG.
Rough Idling and Stalling
An incorrect temperature reading can cause the PCM to adjust idle speed improperly. This can lead to a rough idle, stalling when coming to a stop, or difficulty starting, especially when the engine is cold.
Check Engine Light Illumination
The PCM constantly monitors the ECT sensor’s readings. If the readings fall outside expected parameters, or if the sensor itself fails its internal diagnostics, the PCM will trigger the check engine light. The diagnostic trouble code (DTC) associated with a faulty ECT sensor is often P0115, P0116, P0117, P0118, or P0119, depending on the specific fault.
Overheating Issues
In some cases, a faulty sensor might not signal the fans to turn on, or it might signal the wrong fuel mixture for the actual engine temperature. This can lead to the engine overheating, especially under load or in hot weather.
Troubleshooting Beyond the Sensor Location
If you’ve confirmed the 2017 Ford Escape temperature sensor location and replaced the sensor, but the problems persist, there are other areas to investigate.
Wiring and Connector Issues
- Inspect the wiring harness leading to the ECT sensor for any signs of damage, fraying, or corrosion.
- Check the electrical connector for bent pins, corrosion, or loose connections. A poor connection can cause intermittent issues.
Thermostat Malfunction
- If the temperature gauge is consistently reading too high, the thermostat itself might be stuck closed, preventing coolant from circulating properly.
- Conversely, a thermostat stuck open will cause the engine to take a very long time to reach operating temperature, leading to poor performance and fuel economy.
Radiator and Cooling Fan Problems
- Clogged radiator: Debris or internal corrosion can restrict coolant flow, leading to overheating.
- Faulty cooling fan motor or relay: If the fans aren’t spinning when the engine gets hot, the cooling system can’t dissipate heat effectively.
Water Pump Issues
- A failing water pump can lead to insufficient coolant circulation, causing the engine to overheat. Signs include coolant leaks from the pump area or a whining noise from the front of the engine.
