Code result
P0111
Intake Air Temperature Circuit Range/Performance
Moderate severity
What it means
The intake air temperature (IAT) sensor reading does not change plausibly with engine warm-up or after driving begins. Many vehicles share the IAT into the MAF housing; on those, MAF replacement also replaces IAT.
Is it safe to drive?
Use caution
The vehicle is usually drivable for short distances, but the problem can worsen or affect emissions. Diagnose and repair as soon as practical.
Most likely causes
