This automotive maintenance tutorial was specifically written to assist owners of the second generation 2015, 2016, 2017, 2018 and perhaps also the revised 2019, 2020, 2021 and 2022 model years of the Ford Edge SUV in cleaning or changing the IAT (intake air temperature sensor) attached to the engine air filter box for the EcoBoost 2.0L turbocharged I4 engine.

Owners of other Ford and Lincoln vehicles such as the Escape, Expedition, EcoSport, Flex, Explorer, Fiesta, Focus, Fusion, Mustang, Taurus, Ranger, Transit Connect, F-150, Endura, C-Max, Kuga, Mondeo, MKZ, Navigator, Aviator, Nautilus and Continental may also find these DIY instructions to be helpful.

The original OEM intake air temperature sensor part number is FoMoCo DS7A-12A697-AA (also known as DS7A 12A697 AA or DS7A12A697AA).

A compatible replacement Ford sensor with its part number is Motorcraft DY1267.

A compatible aftermarket IAT sensor is the Standard Ignition AX422.

The sensor is also known as the "intercooler charge temperature" sensor or "air charge temperature" (ACT) sensor.

If you have a CEL / SES (check engine or service engine soon) light on the gauge cluster use an OBD2 scan tool (also known as an OBDII scanner). Some of the IAT sensor related DTC (diagnostic trouble or "error" codes) you might see include P0110, P0111, P0112, P0113 or P0114.

If you would like to try cleaning your old IAT sensor before purchasing a new one, you can use CRC Electronic Cleaner or MAF Cleaner (mass air flow cleaner).

The first few steps are to turn off the ignition, open the hood and then move to the right (driver) side of the engine bay.

The IAT sensor is attached to the front of the plastic air intake tube near the rubber air intake hose attached to the engine air filter housing.

Gently rotate the sensor 1/4 turn in the counterclockwise direction before pulling it straight out of the air box.


Push In Release Tab
Disconnect Power Plug
Inspect Electrical Contacts
Do not use excessive force. The sensor should turn relatively easily.

If you use excessive force, you may break the small plastic tab that sticks out of the sensor.

Push in the release tab on the black plastic electrical connector before sliding it straight off the old sensor.

Inspect Sensor Wire
DS7A 12A697-AA
FoMoCo Part Number
Inspect the electrical contacts and the sensor wire.

If the old sensor is covered in soot, dust or oil, it may have been the cause of any problems with the engine including hesitating, stalling, rough starting, loss of power, slow acceleration and lowered fuel economy / increased fuel consumption (reduced MPG).

Carefully spray the sensor wire with the electronic cleaner or mass air flow cleaner.

An optional step is to very lightly wipe the sensor wire with a paper towel or a Q-tip cotton swab.

If you do wipe the sensor wire with a paper towel, avoid flexing or bending the wire. Be sure to use a very gentle touch to avoid damaging the wire.

Allow the sensor to air dry before re-installing it.

Port In Air Intake Tube
Line Up Sensor
Install New Sensor
Line up the plastic tab on the sensor with the opening in the air intake tube.

Re-insert the sensor and gently rotate it 1/4 turn in the clockwise direction to secure it into place.

Avoid using excessive force.

1/4 Turn Clockwise - Lock
Push On Power Plug
New Sensor Installed
Push the electrical connector straight on to the sensor.

The power plug should "click" securely into place.

Turn on the ignition and check for any DTC (diagnostic trouble codes or "error codes") on the gauge cluster.

If you do have an IAT sensor related trouble code, use an OBDII scanner to clear the code.

Be sure to write down the sensor cleaning or replacement in your vehicle's service records.
