Q: MAF Sensor

asked by on August 09, 2017

(2009 corolla S with 119k miles) I replaced my MAF sensor and drove to work and back after using a diagnostic tool. After a full day of driving, my MIL light came back on and received the same error code as before (system running too lean). Now what? What can still be causing the error? Please help, thanks!

My car has 119000 miles.
My car has an automatic transmission.
