P0113
Intake Air Temperature Sensor Circuit High Input
Quick answer: P0113 means intake Air Temperature Sensor Circuit High Input. Fixing the underlying cause typically runs $100 to $460 at an independent shop. Usually safe to drive.

What P0113 means
The intake air temperature sensor tells the computer how hot the air entering the engine is, so it can trim the fuel mixture. A high input reading means the circuit's voltage is pegged at the top, which the computer interprets as impossibly cold air. That pattern points at an electrical open (a disconnected or broken circuit) far more often than at a genuinely bad sensor.
Common symptoms
What drivers usually notice with this code.
- Check-engine light with little or no change in how the car drives
- Hard starting when the engine is cold
- Slight hesitation or rough running during warm-up
- Minor drop in fuel economy
- A scan tool showing an intake air temperature that is obviously wrong, like 40 degrees below zero on a summer day
Common causes
Ranked from most to least likely.
- 1A disconnected or loose IAT sensor connector, often knocked off during other under-hood work (check this first, since it costs nothing)
- 2A broken, chafed, or corroded wire in the sensor circuit, creating an open
- 3A failed IAT sensor element (on many vehicles the IAT is built into the mass airflow sensor, which changes the price a lot)
- 4Corrosion or a spread pin inside the connector, common on older or salt-belt vehicles
- 5A rodent-chewed harness section near the intake
- 6A failed engine control module, which is genuinely rare and should be the last thing anyone suggests
Can I keep driving?
Yes, the car will run and drive normally in most cases, though it may run slightly rich or hesitate when cold until you fix it.
Severity: Low. A flashing check-engine light always means stop, whatever the code says.
Ballpark cost
What P0113 usually costs to fix
A range, not a quote. What you pay depends on your vehicle, your area, and which of the causes above turns out to be the real one.
Typical parts and labor at an independent shop. Dealer rates run higher.
That spread is wide on purpose. P0113 points at a system, not a single part, so the real answer depends on what the diagnosis finds. Use the range to know what to expect. If an estimate comes in higher, it usually means the specific repair is more involved, and it is always fair to ask what is included.
Next steps
What to do next
Pop the hood and look at the sensor connector on the intake tube or airbox; a connector that has simply fallen off is a free fix and it happens more often than you would think. If the connector is seated, a shop can check the circuit in a few minutes, and a standalone IAT sensor is typically a $75 to $150 job. The price only climbs if your IAT is integrated into the MAF sensor, in which case the whole assembly gets replaced.
Walk in informed
Ask for the diagnosis in writing and which test confirmed it, so you understand exactly what is being fixed. Fixxr shows you what the job typically costs near you, so you can approve the work with confidence.

Can I drive with a P0113 code?
Yes, the car will run and drive normally in most cases, though it may run slightly rich or hesitate when cold until you fix it.What does the P0113 code mean?
The intake air temperature sensor tells the computer how hot the air entering the engine is, so it can trim the fuel mixture.

That pattern points at an electrical open (a disconnected or broken circuit) far more often than at a genuinely bad sensor.What are the most common causes of a P0113 code?
The most likely causes, roughly in order, are a disconnected or loose IAT sensor connector, often knocked off during other under-hood work (check this first, since it costs nothing); a broken, chafed, or corroded wire in the sensor circuit, creating an open; a failed IAT sensor element (on many vehicles the IAT is built into the mass airflow sensor, which changes the price a lot); corrosion or a spread pin inside the connector, common on older or salt-belt vehicles.

Fixing the underlying problem behind a P0113 code typically runs $100 to $460 at an independent shop, including parts and labor. The exact figure depends on your vehicle and which part turns out to be at fault.
You deserve a fair fix.
