My Jetta has 2 codes popping up from the check engine light. The one is P1580 which means I have a throttle actuator B1 malfunction and the other is P0103 which means MAF sensor circuit high input. Now I am a woman and only know a little bit about working on vehicles so I have no idea what half of this is and I would like to know what I can do to fix it. By the way I believe I just got a new MAF sensor professionally put in just a few months ago. And please speak to me in english. I would like to fix the problem myself. Another question I have is what is a throttle actuator B1?

First I would like to ask if your battery has been low, dead, disconnected lately, it can cause this problem if the specifications between.

But heres what it stops with you doing it yourself im afraid.

First you can make sure the battery is good, and properly charged.

Second step would be to erase the dtcs with a scan tool, right after that you will have to do the throttle body adaption procedure and re-erase the dtc codes again. Then set the ready code.

Should be good to go!

DTC is diagnostic trouble codes
