Can You Use Mass Air Flow Cleaner To Clean A Throttle Body

Using a mass airflow cleaner on a throttle body

If your vehicle is showing signs of a rough idle, loss of power, or even a "Check Engine" light warning, there's a skilful chance that your Mass Air Period (MAF) sensor is dirty.

These days, about fuel-injected engines are equipped with a MAF sensor; this device measures the amount (and density) of air entering the engine. The computer so uses this data to determine how much fuel must exist injected into the engine.

In most cases, the MAF sensor gets muddy with accumulated droppings, usually oil, grit and pollen that can cause inaccurate sensor readings and negatively affect the engine's air-to-fuel ratio.

Signs of a dirty MAF sensor include:

Loss of engine ability
Poor fuel economy
Stalling
Rough idle, and…
Excessive emissions

Check engine light due to a dirty mass airflow sensor

Technicians, and other DIY automotive enthusiasts, will often try to use throttle body cleaner, carburettor cleaner, or fifty-fifty brake-role cleaner to make clean the engine's MAF sensor. These cleaners are oftentimes far too aggressive for this awarding and run the risk of warping or damaging sensitive components – including the plastic housing that surrounds the MAF sensor.

CRC's Mass Air Flow Sensor Cleaner is specifically developed to clean MAF sensors without damaging or degrading plastic, painted surfaces or sensitive components.

Here'due south how to utilize CRC's Mass Air Flow Sensor Cleaner…

Apply CRC'due south Mass Air Flow Sensor Cleaner with the engine off
Unplug the MAF wiring harness
Remove the vehicle'due south air filter to gain access to the MAF sensor (usually located between the air box and the throttle trunk)
For all-time results, information technology's recommended to remove the sensor, but it's not absolutely necessary
Apply 10 to 15 short bursts of CRC MAF cleaner to the hot wire or hot plate
Keep the terminate of the straw 100 to 120 mm away from the hot wire while spraying
Permit to dry out thoroughly before starting the engine

The to a higher place process takes nether 10 minutes to perform and should be done every fifteen 000 to twenty 000 km. Or alternatively, every time the engine's air filter is replaced.
