2013 Ford Escape 1.6 Cylinder Head Temperature Sensor Location
The cylinder head temperature (CHT) sensor on the 2013 Ford Escape 1.6L EcoBoost is located on the rear of the cylinder head, specifically on the driver’s side near the vacuum pump. Accessing this sensor typically requires removing the upper cowl or working blindly behind the engine block to disconnect the electrical harness and unscrew the unit. Replacing a faulty CHT sensor is vital for preventing engine overheating and clearing “Limp Home” mode errors.
Have you ever been driving your Ford Escape when suddenly the temperature gauge spikes and the car loses power? It is a stressful moment that often points to a single, hidden component failing under the hood. You might feel overwhelmed by the tight engine bay, but understanding the layout can save you hundreds in labor costs.
I have spent years wrenching on EcoBoost engines and I know exactly how frustrating these “hidden” sensors can be. In this guide, I will walk you through the exact 2013 ford escape 1.6 cylinder head temperature sensor location and provide a clear path to fixing it yourself. We will cover the tools you need, the safety steps to follow, and how to ensure your cooling system is back in peak condition.
By the end of this article, you will have the confidence to tackle this repair and get your Escape back on the road. We are going to look at why this sensor is different from a standard coolant sensor and how to troubleshoot the common codes associated with it. Let’s dive into the engine bay and get to work.
The Exact 2013 ford escape 1.6 cylinder head temperature sensor location
Finding the CHT sensor on the 1.6L EcoBoost engine is the hardest part of the entire job. Unlike older vehicles where sensors sit prominently on top of the engine, Ford tucked this one away on the firewall side of the cylinder head. If you are standing at the front of the car looking at the engine, the sensor is located on the back-left (driver’s side) of the head.
It is positioned just below the vacuum pump and near the high-pressure fuel pump area. Because it is screwed directly into the metal of the cylinder head, it doesn’t actually touch the coolant. It measures the metal temperature of the head itself, which provides a much faster and more accurate reading if you lose coolant suddenly.
To see it, you will likely need a bright flashlight and a small inspection mirror. Look past the air intake tube and down toward the back of the engine block. You will see a small electrical connector with two wires leading to a sensor threaded into the aluminum head. This specific 2013 ford escape 1.6 cylinder head temperature sensor location makes it difficult to reach without some patience and the right extensions.
Visual Cues for Identification
The sensor itself is relatively small, usually featuring a brass body and a plastic electrical connector. On the 1.6L EcoBoost, the wiring harness often has a heat-shielding sleeve over it because of its proximity to the exhaust and turbocharger components. Look for a wire loom that dives down behind the cylinder head near the transmission bell housing area.
If you see a sensor sticking out of a plastic pipe, that is likely the Engine Coolant Temperature (ECT) sensor, not the CHT. The CHT is always threaded directly into the metal of the engine. Distinguishing between these two is critical for a successful diagnostic process.
CHT Sensor vs. ECT Sensor: What Is the Difference?
Many DIYers confuse the CHT (Cylinder Head Temperature) sensor with the ECT (Engine Coolant Temperature) sensor. While they both monitor heat, they serve very different roles in the 2013 Ford Escape. The ECT sensor sits in the coolant stream and tells the computer how hot the liquid is.
The CHT sensor is a “dry” sensor. It measures the actual temperature of the aluminum cylinder head. This is a safety feature designed by Ford to protect the engine if a coolant hose bursts. If there is no liquid in the engine, an ECT sensor cannot read anything, but the CHT sensor will immediately detect the rising metal temperature.
When the CHT sensor detects extreme heat, it triggers Fail-Safe Cooling. This mode shuts down half of the cylinders to pump air through the engine, effectively using the pistons as air pumps to cool the block. If your Escape is chugging and has no power, your CHT sensor is likely doing its job—or it has failed and is sending a false signal.
Essential Tools for Replacing the CHT Sensor
Before you start digging into the 2013 ford escape 1.6 cylinder head temperature sensor location, gather your tools. You do not want to be halfway through the job only to realize you can’t reach the bolt. Because space is tight, specialty extensions are your best friend here.
- 19mm Deep Socket: Most CHT sensors require a 19mm deep socket to clear the plastic connector.
- Long Extensions: You will need at least 10 to 12 inches of extensions to reach behind the head.
- Swivel Joint (U-joint): This allows you to get the socket onto the sensor at an angle.
- Flashlight or Headlamp: It is dark back there, and you need both hands free.
- Magnetic Pickup Tool: Just in case you drop the sensor or your socket into the abyss of the engine bay.
- Dielectric Grease: To protect the new electrical connection from moisture and corrosion.
I also recommend having a torque wrench. While many mechanics tighten these by feel, the cylinder head is aluminum. Over-tightening can strip the threads, turning a simple sensor swap into a nightmare repair involving Helicoils or head replacement.
Step-by-Step Replacement Guide
Now that you know the 2013 ford escape 1.6 cylinder head temperature sensor location, let’s walk through the removal and installation. Safety is paramount, so ensure the engine is completely cold before you begin. You will be reaching near the turbo and exhaust manifold, which stay hot for a long time.
1. Clear the Path
To get the best access, remove the plastic engine cover by pulling it upward. Some technicians prefer to remove the windshield wiper cowl and the battery box to create more room. If you have small hands, you might skip this, but for most, removing the cowl is worth the extra 15 minutes.
2. Disconnect the Electrical Connector
Reach behind the engine and locate the wiring harness. There is a small tab on the connector that you must squeeze or lift to release. Be gentle; these plastic clips become brittle over time due to engine heat. Once disconnected, move the wire out of the way.
3. Remove the Old Sensor
Slide your 19mm deep socket and swivel extension onto the sensor. Ensure the socket is fully seated before applying pressure. Turn counter-clockwise to loosen. Once it is loose, you can usually unscrew it the rest of the way by hand. Since this is a “dry” sensor, no coolant will leak out when you remove it.
4. Install the New CHT Sensor
Thread the new sensor in by hand first. This is the most important step to prevent cross-threading. Once it is finger-tight, use your torque wrench to tighten it to the manufacturer’s specification (usually around 8-12 lb-ft, but check your specific manual). Reconnect the electrical plug until you hear a click.
Common Symptoms of a Failing CHT Sensor
How do you know if the 2013 ford escape 1.6 cylinder head temperature sensor location is even the place you should be looking? Faulty sensors usually leave a trail of breadcrumbs. The most common sign is the cooling fans running on high the moment you start the car, even when it is freezing outside.
You might also see the temperature gauge on the dashboard behaving erratically. It may sit at “Cold” for a long time and then suddenly jump to “Hot.” In many cases, the car will enter Limp Home Mode, restricting your speed to protect the engine from perceived overheating. This is often accompanied by a “Service Engine Now” message.
Finally, check for specific OBD-II trouble codes. Codes like P1289 (CHT Sensor Circuit High Input) or P1299 (Cylinder Head Over-temperature Protection Active) are dead giveaways. If you see these, it is time to inspect the sensor and its wiring harness for damage or corrosion.
Safety Precautions and EcoBoost Specifics
Working on a 2013 Ford Escape 1.6L requires an extra layer of caution. This specific engine was subject to significant recalls regarding the cooling system. If your sensor is failing because the engine actually is overheating, you could be at risk of a cracked cylinder head or an engine fire.
Always check your coolant level in the expansion tank. If it is low, do not just replace the sensor and keep driving. You must find where the coolant is going. The 1.6L EcoBoost is known for coolant intrusion into the cylinders, which can mimic a sensor failure but is actually a much more serious mechanical issue.
If you see white smoke from the exhaust or feel a misfire on cold starts, stop immediately and consult a professional. Replacing the sensor will not fix a cracked block. However, if your coolant levels are fine and the car is just throwing “false” overheating codes, the sensor replacement is the correct path forward.
Troubleshooting Common Error Codes
When you plug in a scanner and see codes related to the 2013 ford escape 1.6 cylinder head temperature sensor location, don’t just clear them. You need to understand what the computer is trying to tell you. Diagnostic codes are the language of your car’s brain.
P1289 – CHT Sensor Circuit High
This code usually means the computer sees infinite resistance, which points to a broken wire or a sensor that has internally failed. Check the connector for green corrosion or wires that have been chewed by rodents. If the wiring looks good, the sensor is likely “open” and needs replacement.
P1299 – Over-temperature Protection
This is the “scary” code. It means the sensor actually detected a temperature high enough to damage the engine. If you get this code along with a P1289, the sensor is likely lying. But if you get P1299 alone, your engine was truly overheating. Ensure your thermostat and water pump are functioning correctly before blaming the sensor.
Frequently Asked Questions About 2013 ford escape 1.6 cylinder head temperature sensor location
Where is the CHT sensor located on a 1.6L EcoBoost?
It is located on the back of the cylinder head, on the driver’s side, near the vacuum pump. You have to reach between the engine and the firewall to find it.
Can I drive with a bad CHT sensor?
It is not recommended. A bad sensor can put the car into “Limp Mode,” reducing power significantly. It also prevents the computer from protecting the engine if a real overheating event occurs.
Do I need to drain the coolant to change the CHT sensor?
No. The CHT sensor is a dry sensor that sits in a “blind hole” in the cylinder head. No coolant will escape when you remove it, making it a relatively clean job.
Why are my cooling fans running constantly?
When the CHT sensor fails or sends an irrational signal, the ECU (Engine Control Unit) turns the fans on high as a failsafe to prevent potential engine melting. Replacing the sensor usually fixes this.
Is the 1.6L CHT sensor the same as the 2.0L?
While they function similarly, the 2013 ford escape 1.6 cylinder head temperature sensor location and the part itself can vary. Always buy the sensor specifically matched to your VIN and engine size to ensure the connector pins match.
