My check engine light had been on for a couple of years but I could not figure out the cause. Finally the mass air flow sensor failed. The light finally went off after the sensor was replaced.
I have a new mass airflow sensor and a new 02 sensor but it is still reading lean on bank 1 and bank 2 so I just don't know what to do.
I used to have 6 pages of check engine problems. I have fixed every thing and then it goes back to map, why
I had to replace my Mass Air Flow Sensor on my 2001 chevy prizm (toyota engine). For $80 bucks at Kragen and a easy install by myself and my sister (we watched a video on youtube on how to fix it) it worked! the check engine light went off and has been off ever since! But before you buy a ne part, try carb cleaner and give it a good rub off. Sometimes that works. But my C.E.L was on for about 2 years so it didnt work for mine. But 90% of the time it is this problem with our make so I recommend trying! :)
The car was slow to start and slow to go in the mornings. The mass air flow sensor was replaced, and now it runs great.
