Hi. The power disappeared, and the check engine lamp is on. I turned on DTC and i got P0102. Then i checked MAF sensor 3 and 2 pin and i got 0,45v. I checked the wires until ECU and everything was fine. Do you know where the problem is?
Thank you

Hello,

This Direct Trouble Code (DTC) is for a short to ground or an open in the wiring for the Mass Airflow Sensor (MAF) wiring. I have included for you in the diagrams down below a diagnostic troubleshooting guide for this DTC. You will need to use a multi-meter for the tests. so I have included a link below for you to go to if you are unfamiliar with how to use one below:

Please go through these guides and get back to us with what you are able to find out.

Thanks,
Alex
