Save the exact code, accompanying faults and available data. Identify the cause on your particular vehicle before buying parts. Clear the code only after repair.
What P0113 actually describes
P0113 means intake-air temperature sensor 1 circuit high input. The engine computer has detected a signal outside its expected range according to its monitoring strategy. ‘High’ refers to the circuit signal, not necessarily a high air temperature. An implausible displayed temperature may be a clue, but its meaning depends on the vehicle and when it was measured.
The sensor, connector or wiring may be involved. On some vehicles the temperature measurement is integrated with another sensor assembly. Do not order a separate IAT sensor from the short app description alone. P0101 is a different airflow-related code; if both appear, the garage needs the complete picture.
Decide what to do from the symptoms
Record whether the warning lamp is steady or flashing and whether starting, idle or acceleration has changed. Severe misfiring or a marked loss of power calls for professional advice before driving on. P0113 alone cannot establish a safe driving distance.
If the lamp is steady and the car behaves normally, arrange a diagnosis and keep the stored evidence. Clearing the code before that visit can remove useful context without fixing anything.
| Vehicle | Engine, build dates and market | Documented concern |
|---|---|---|
| 2015 Jeep Renegade BU | 2.4 L ED6; built 8 January–4 November 2015; NAFTA | Strain at the IAT connector may compromise the wires; the bulletin describes a jumper harness. |
| 2016 Fiat 500X FB | 2.4 L ED6; same build window and market | The same targeted connector and wiring concern is documented. |
Manufacturer document, not an OBDPhone® test of these engines. These are build dates, not registration dates. Do not transfer this bulletin to European cars or other engines without checking applicability.
What the FCA bulletin can and cannot establish
FCA US bulletin 08-002-16, dated 9 January 2016, links P0113 on the specified vehicles to possible wire strain at the IAT connector. Its service route involves vehicle-specific diagnosis and a jumper harness. It does not say that every P0113 has this cause or that the kit belongs on a different car.
The transferable lesson is to check whether the code is active or stored, note other faults, inspect the connector and wiring, then use the correct service data. Electrical testing and harness work belong with a qualified technician. Official source last checked 1 October 2026.
Bring a useful record to the garage
Photograph the scan and dashboard warning before anything is erased. Save P0113, its status, associated codes and available freeze-frame data. Record the model, year, exact engine if known, mileage and when the light appeared. Missing app data does not prove a healthy circuit.
Mention recent air-filter or intake work and when symptoms occur. Ask the technician to confirm where the sensor sits on your exact version and to assess connector, wires and circuit against its service information. Avoid unplugging components on a hot or running engine to experiment.

- Available engine and freeze-frame data before clearing.
- Starting, idle, acceleration and warning-lamp behaviour.
- Vehicle details, mileage and recent work.
Where OBDPhone® helps
OBDPhone® reads generic engine and emissions fault codes and available engine data. It helps you share P0113 and context with a repairer; it cannot physically test a sensor, plug or wire. A scan with no additional codes does not certify the system.
Only clear after the fault has been repaired and the information saved, then check whether it returns. ABS, airbag, traction battery, coding, programming and manufacturer-specific functions are not guaranteed. Check compatibility or contact support@obdphone.com.

Frequently asked questions
The essential answers.
Does P0113 mean the intake air is too hot?+
No. Circuit high describes the monitored electrical signal; the code alone does not measure actual air temperature.
Must I replace the IAT sensor?+
Not from the code alone. Connector, wiring and vehicle-specific checks should guide that decision.
Does the Jeep and Fiat bulletin cover my European car?+
Not automatically. It is limited to specified 2.4 L ED6 vehicles built in a defined period for NAFTA. Check the VIN and local service information.
Can I clear P0113 to see whether it comes back?+
Save the evidence first. Clear only after repair; clearing does not mend the circuit.
This guide supports an initial understanding. It does not replace the vehicle manual, manufacturer safety instructions or an assessment by a qualified professional.
