I have a 1999 RAV 4 For the past week i have been gettIng this code P0171, i know what this means (system to lean) and it has to do with the MAF sensor.

Could anybody tell me where is the MAF sensor?

Appreciate all of your help

JM, the MAF should be located on the intake tube a few inches above where the airbox is. Below is a DIY for cleaning the MAF/TB on a 4Runner/Taco, but I would assume the location of the MAF should be similar on a Rav. Just remember to use a spray cleaner specifically designed to clean the MAF and never ever use a Q-Tip to clean the sensor wires. If you break the wires the sensor is a very costly replacement, good luck and keep us updated. Welcome to too!
