Drive with caution — fix soon.
This code means the engine computer detected a problem with the intake air temperature sensor circuit, which measures how warm or cold the air entering your engine is. The most common fixes are replacing a faulty IAT sensor or repairing damaged wiring or a loose connector. It's a fairly common code and is usually inexpensive to fix without any major engine work.
$80 – $250
Varies by vehicle and root cause.
Yes, in most cases you can keep driving for a while since this is a sensor circuit issue, not a mechanical breakdown. You may notice slightly worse fuel economy or a rougher idle, but it's safe for short trips. Just get it diagnosed soon to keep the engine running its best.
Most repairs run between $80 and $250. If it's just a wiring or connector fix, it can be on the lower end, while replacing the IAT sensor itself adds parts cost. A shop will usually confirm the cause before charging for parts.
It's generally considered low to moderate in seriousness because it affects a sensor rather than a core engine part. Left alone, it can hurt fuel economy and engine smoothness over time. It's worth fixing soon but it's not an emergency.
It's usually found in the air intake tube or built into the mass airflow (MAF) sensor near the air filter box. Its job is to tell the computer how warm the incoming air is so fuel can be adjusted correctly. A quick inspection of this area often reveals a loose connector or damaged wire.
