P0113 is reported as intake-air temperature signal high. The next step depends on the full scan and the exact vehicle, not the code alone.
If braking, steering, power, temperature, smoke, or fuel smell is abnormal, stop safely; otherwise save the full scan and arrange diagnosis.
This Ford document supports only its stated code and vehicle context. The code alone cannot identify a failed part, prove that another make uses the same definition, or clear a car for driving. Compare your full scan with the current exact-vehicle service information.

What this code means
P0113: Intake-air temperature signal high. This is a source-scoped technical description. It does not prove that any named component has failed.
Namespace obd_reference
Make scope No exact vehicle application established
Definition status source supported definition vehicle applicability unverified
Why this exact code matters
This is an intake-air-temperature signal-high report. It is not a coolant-temperature or thermostat code. Save the measured temperature and ambient/startup condition for a shop to check the sensor circuit.
Compare P0128: coolant warm-up. A related code is a different observation, not a second diagnosis.
Evidence to save for this code
- Cold versus warm operation
- Ambient, intake and coolant freeze-frame values
Keep the complete module scan and any accompanying warning; a single emissions code cannot show every relevant fault.
Ask for a measured diagnosis
- Does a sensor/circuit bias, thermostat operation, coolant loss or software condition explain the monitor?
- Is the required coolant specification known for the exact vehicle?
The Temperature sensor and thermostat monitoring guide has the shared system checks and after-repair questions. Those broad checks apply to a system, while the meaning above is specific to P0113.
Vehicle and scanner limits
We have not verified this code for every make, model, year or engine. A generic emissions scanner may not read the body, chassis, transmission or EV module that holds related faults. Compare the full scan with the owner manual and manufacturer service information.
