Drive with caution — fix soon.
This code means the intake air temperature sensor signal is dropping out or changing erratically rather than failing completely, which usually points to a loose connector or intermittent wiring fault. Common fixes include securing or repairing the wiring and connector, cleaning corroded pins, or replacing the IAT sensor. Because intermittent faults can be tricky to pin down, a careful inspection of the harness is often the key.
$80 – $260
Varies by vehicle and root cause.
Usually yes, but the intermittent signal means the car can occasionally idle rough or hesitate. It's safe for short trips and normal commuting, though the underlying wiring problem can worsen. Getting it inspected soon helps avoid a sudden no-start or a more stubborn fault.
Most repairs cost between $80 and $260. A simple connector or wiring repair sits at the lower end, while sensor replacement plus diagnostic time pushes it higher. Intermittent faults sometimes take extra diagnostic effort to locate.
It's moderate in severity. The intermittent signal won't usually strand you, but it can make the engine run inconsistently and may signal worsening wiring. It's best fixed before the fault becomes constant.
Because the fault comes and goes, the problem may not show up while a technician is testing the car. Mechanics often wiggle-test the wiring and connector to recreate the dropout. This intermittent behavior is exactly what the code is reporting.
