How often should a throttle body be cleaned?

Makers do not give an interval in the schedules checked here. Consider it when there is a drivability problem like rough idle, not at a mileage.

Is throttle body cleaning necessary?

Not as routine maintenance. No manufacturer schedule we checked lists it. It can fix a symptom like a rough idle, so it makes sense only when there is one.

When manufacturers actually call for it

Throttle body cleaning does not appear in any maker schedule opened here (Toyota, Ford, Mazda, Nissan, Subaru). It is a fix for a symptom such as rough idle, not scheduled maintenance.

What it typically costs

$200 to $300professional shop service, Jerry: How Much Does It Cost to Clean a Throttle Body?

National ranges; a dealer usually sits at the top. A quote a little over the range is normal. Well over it is worth a question.

Doing it yourself: A spray cleaner does most of the job for about $10 to $20, per Jerry's estimate guide.

What to ask at the counter

“Is throttle body cleaning in my manufacturer's schedule?”
“What symptom are you seeing, such as rough idle or stalling, that points to the throttle body?”
“Is there a trouble code or a technical bulletin for my car that calls for it?”
