Question

how do you clean air flow sensor

Answer 1

HI there,

Cleaning the maf sensor doesn't usually resolve this problem or these codes. To clean it, get some maf sensor cleaner. Follow the instructions on the can. To remove the maf sensor, you can unplug it and remove the tamper proof screws that hold just the sensor in place and pull it out. Or, remove the air fllter box and take out the 4 bolts that hold it to the box.
