P0102 Mercedes-benz -year 2006

Question

Censor was replaced, still dong the samerhing, check engine light back on with same code p0102?

Answer 1

P0102 Mass airflow sensor circuit low input

The code returns, P0102 can also mean the MAF sensor has a open connection or poor connection to the MAF sensor. Check the connection for proper connection

 Other factor that can set a MAF code would be a plugged exhaust system , you would know you have a plugged exhaust if the vehicle start out nice and strong then looses power as you accelerate, the other is a vacuum leak, when it comes to a MBZ you can probable hear  the vacuum leak,  these are the 2 area that can also set a P0102 code to set.
