P0113

Intake Air Temperature Sensor 1 Circuit High Bank 1

Fuel & air metering Generic OBD-II Low

What it means

P0113 means the intake air temperature sensor circuit is reading a higher-than-expected voltage, which the ECM interprets as an implausibly cold intake temperature — typically caused by a failed sensor or an open in its wiring. It won't leave you stranded, but the wrong air-temp reading can skew fuel mixture, hurting economy and cold-start smoothness.

Low

Can I keep driving? Safe to keep driving — the car runs, though fuel trims may be off, so expect slightly worse economy and mild hesitation until it's fixed.

How to diagnose & fix

Work through it in order

Read the live IAT value with a scan tool — a high-input fault usually shows an implausibly cold reading.
Inspect the sensor connector and wiring for corrosion, damage, or an open circuit.
Back-probe the signal wire; if voltage stays high with the connector bridged, the wiring or ECM side is at fault, otherwise replace the sensor.
Replace the IAT sensor if it reads out of range with good wiring. Clear and re-test.

FAQ

Quick answers

Is it safe to drive with P0113?+

Yes. The engine will run and won't stall from this code — you'll just see mildly worse fuel economy and possibly slightly harder cold starts until it's repaired.

Can I just clear P0113?+

You can, but if the sensor or its wiring is genuinely faulty the code returns once the ECM re-checks the circuit.
