P0113: Intake Air Temperature Sensor 1 Circuit High

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 è un codice diagnostico di guasto relativo a emissioni, classificato con gravità low. Quando la centralina (ECU) del tuo veicolo rileva questa condizione, memorizza P0113 e accende la spia motore.

Se il tuo veicolo ha attivato P0113, potresti notare uno o più di questi sintomi:

• Check engine light on
• Slightly rough idle, especially on cold starts
• Marginally higher fuel consumption
• Possible hard starting in cold weather
• Minor hesitation on acceleration

Ecco le cause più comuni di P0113, ordinate in base alla probabilità che siano la causa del problema:

In genere sì, per brevi tragitti. Generally safe to drive. The ECU will use a default air temperature value, which may slightly reduce fuel efficiency and performance. Repair at your convenience but do not ignore indefinitely.

Segui questi passaggi per individuare la causa principale di P0113:

1. 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
2. Inspect the electrical connector for corrosion, bent pins, or disconnection. Clean with electrical contact cleaner and reseat the connector firmly
3. 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
4. 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
5. If the sensor tests fine, check wiring continuity between the sensor connector and the ECU. Repair any open or damaged wires

I costi di riparazione di P0113 variano a seconda della causa principale e del tuo veicolo. Ecco le stime tipiche:
