Toyota Repair: 2000 toyota celica gt, celica, MAP

Question
My "check engine light" came on and after I have it analized it showed a PO171 code and I read your recommendation to replace the MASS AIRFLOW SENSOR (MAS). I would like to do it myself, can you tell me where I can find this Sensor? Thanks for your help and time.

Answer
Your MAF sensor should be downstream of your air filter and upstream your intake manifold.  Normally it is next to the air filter before the flexible hose.  It has an electrical plug which you need to detach.  Disconnect the flexible air hose from the MAF sensor, then disconnect the MAF sensor from the Air Filter housing.
