Can drive — fix at your convenience.
This code means the intake air temperature sensor is working but reporting readings that don't match what the computer expects, often because the value is stuck or out of its normal range. Typical fixes include cleaning or replacing the IAT sensor, repairing a wiring issue, or addressing a dirty air filter affecting airflow. It's a low-severity code that's usually straightforward and affordable to repair.
$75 – $220
Varies by vehicle and root cause.
Yes, this is a low-severity code and you can typically keep driving normally. The sensor is reading a bit off rather than failing, so you'll mostly notice minor effects like slightly worse mileage. Still, plan to have it checked within a week or two.
Repairs usually fall between $75 and $220. Cleaning the sensor or replacing an air filter is cheaper, while a new IAT sensor adds modest parts cost. Diagnosis time may be included in the shop's estimate.
No, it's one of the milder codes you can get. It affects sensor accuracy and mild engine performance rather than anything that could leave you stranded. Fixing it keeps your fuel system tuned and your light off.
It can contribute, since a clogged filter changes how air flows past the sensor and can throw off temperature readings. Replacing a neglected air filter is a cheap first step worth trying. If the code returns, the sensor or wiring is the more likely culprit.
