Fault code P0113 means intake air temperature sensor signal too high. The sensor reports an implausibly high temperature, usually because of an open circuit.

Typical symptoms

• Hard cold starting
• Rising consumption
• Engine light on
• Slightly reduced performance

Most common causes

• Failed IAT sensor
• Broken wiring or oxidised connector
• Faulty sensor integrated in the MAF sensor
• Wrong positioning after a repair

How it is checked in diagnosis

• Reading the air temperature with a cold engine: it must match the ambient temperature
• Measuring the sensor resistance
• Checking wiring continuity

Can you drive with code P0113?

Yes: the impact on driving is limited, but consumption and emissions get worse.

How MasterTuning helps

We read the real values from the ECU, not just the code: that is the difference between identifying the component responsible and replacing parts by trial and error. After the repair we clear the fault and check that it does not come back. Centres throughout Italy.

Frequently asked questions

What does fault code P0113 mean?

Code P0113 means intake air temperature sensor signal too high. The sensor reports an implausibly high temperature, usually because of an open circuit.

Can you drive with fault P0113?

Yes: the impact on driving is limited, but consumption and emissions get worse.

Is clearing code P0113 enough to fix it?

No: if the cause is still present the code comes back after a few kilometres. Clearing should only be done after the repair, with the diagnostic tool.

How much does it cost to fix code P0113?

It depends on the component responsible: the diagnosis is precisely what identifies it with real measurements, avoiding unnecessary replacements that cost far more than the correct repair.
