MAF check engine light - Toyota Yaris Forums

scoobopdan · 10-22-2019, 03:13 PM

Long story short - had a cold air intake on my 08 yaris for 4 years. Had to restart the battery when I first installed it and it had no issue relearning. Had an oil change 3 weeks ago and had the mechanic put on a new filter while it was lifted. He didnt put it on all the way and it fell off, but I caught it after a few miles. Put it on correctly, cleaned the MAF, and reset the computer. Now the MAF is throwing a check engine light randomly but will turn off after the car being off for a while. It's done this 3 times. It always trips while on the highway going up hill. Should I get a new sensor? Any idea what could be causing this?
