P0113 means the intake air temperature (IAT) sensor is reporting an unusually high voltage, which the ECU interprets as extremely cold air temperatures that do not match actual conditions. This almost always points to a wiring fault, a failed sensor, or a disconnected electrical connector rather than a real temperature problem.

P0113 on a Peugeot means the intake air temperature (IAT) sensor is reporting an unusually high voltage, which the ECU interprets as extremely cold air temperatures that do not match actual conditions. This almost always points to a wiring fault, a failed sensor, or a disconnected electrical connector rather than a real temperature problem.

What does P0113 mean on a Peugeot?
Peugeot 208
2012-2024The 1.2 PureTech and 1.6 BlueHDi engines have the IAT sensor in the air intake duct. Connector corrosion is common in humid climates. The sensor itself is inexpensive and easy to access on these models.
What causes P0113 on a Peugeot?
Beyond the generic causes listed on the main P0113 page, these are the Peugeot-specific patterns we see most often:
Peugeot 208IAT connector corrosion from moisture in the engine bay
Peugeot 208Sensor wiring chafed against engine components
How to diagnose P0113 on a Peugeot with OBD2
Follow these steps to pinpoint the root cause of P0113:
- Locate the IAT sensor - it is typically in the air intake tube between the air filter box and the throttle body, or integrated into the MAF sensor housing
- Inspect the electrical connector for corrosion, bent pins, or disconnection. Clean with electrical contact cleaner and reseat the connector firmly
- Read the IAT sensor value with a scan tool. With the engine cold, it should match the ambient temperature. A reading of -40 degrees C indicates an open circuit
- Measure resistance across the IAT sensor terminals. At 20 degrees C, resistance is typically 2,000-3,000 ohms. An open circuit (infinite resistance) means the sensor is faulty
- If the sensor tests fine, check wiring continuity between the sensor connector and the ECU. Repair any open or damaged wires

FAQ: P0113 on Peugeot
What does P0113 mean?
P0113 indicates the intake air temperature sensor circuit is reading too high a voltage, which the ECU interprets as extremely cold air (often -40 degrees C). This is almost always an electrical problem - a disconnected plug, broken wire, or failed sensor - rather than an actual temperature issue.
Is P0113 serious?
P0113 is a low-severity code. The ECU substitutes a default air temperature value, so the engine still runs. You may notice slightly higher fuel consumption and minor performance changes. It should be fixed but is not urgent.
How much does it cost to fix P0113?
This is one of the cheapest codes to repair. An IAT sensor costs 10-50 EUR and is usually simple to replace. If the issue is just a loose connector, the fix is free. Wiring repairs may cost 45-145 EUR if the harness is damaged.
Where is the IAT sensor located?
The IAT sensor is usually in the air intake tube between the air filter box and the throttle body. On many modern vehicles, it is integrated into the mass air flow (MAF) sensor housing. Check your vehicle manual for the exact location.
