The cylinder head temperature (CHT) sensor on a 2013 Ford Escape is mounted on the engine’s cylinder head; exact spot varies by engine, but you’ll typically find it near the thermostat housing or tucked behind the intake manifold with a two-pin connector.
Knowing the location helps with diagnostic work and sensor replacement. The CHT sensor measures the temperature of the cylinder head to aid engine management, especially during cold starts and under load. It is easy to confuse with the coolant temperature sensor (ECT), which is mounted elsewhere on the engine or thermostat housing.
Understanding sensor placement across engine options
Because the 2013 Escape could be equipped with different engines, the CHT sensor’s exact mounting point shifts. The following guidance reflects common placements across typical 2013 Escape engines, but you should consult your vehicle’s service manual for the precise location by engine code and VIN.
- 2.5L Duratec I4: The CHT sensor is usually mounted on the cylinder head and is commonly found toward the front of the engine, near the intake manifold or thermostat area. Access may require removing the engine cover or nearby components.
- 2.0L EcoBoost I4: The CHT sensor is typically on the cylinder head (often on the passenger side bank) and can be tucked behind the upper intake, near the thermostat housing. The two-pin connector is usually visible from above once components are moved aside.
- 3.0L V6 (where applicable): The CHT sensor tends to reside on the cylinder head as well, generally toward the top rear of the engine block and near other head-mounted sensors; access may require removing shielding or parts to reach.
In all cases, the sensor is a small two-pin device threaded into the cylinder head, with a harness that leads to the engine control module. If you’re unsure, check the Ford service documentation for your exact engine code and VIN to confirm the precise location.
Accessing and testing the sensor
Before attempting inspection or replacement, follow these steps to safely access the sensor.
- Disconnect the negative battery cable to prevent accidental shorts or shocks.
- Remove any engine covers or shielding that obstructs access to the cylinder head area where the sensor sits.
- Trace the two-pin sensor connector from the wiring harness to locate the CH temperature sensor on the cylinder head.
- Carefully disconnect the sensor’s electrical connector and inspect the pins for corrosion or damage.
- Using a multimeter, verify the sensor resistance at room temperature and compare to factory specifications; resistance will vary by model year and engine type.
- If replacing, install the new sensor hand-tight, then torque to the manufacturer’s specification if provided in the service manual.
- Reconnect connectors, reassemble any removed parts, reconnect the battery, and perform a test run to ensure the engine management system reads the sensor correctly.
Note: If you’re not comfortable performing electrical inspections or sensor replacement, consider seeking a qualified technician, as improper handling can affect engine performance.
In summary, the cylinder head temperature sensor on a 2013 Ford Escape is located on the cylinder head with placement varying by engine. Use the engine code and VIN to confirm the exact spot, and follow proper safety steps when inspecting or replacing the sensor.
Summary: The CH temperature sensor is head-mounted and engine-dependent; locate it on the cylinder head near the thermostat or behind the intake, verify with your specific engine code, and use careful procedures to inspect or replace it.
