This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic.
What does it mean when your fuel trim code is p0170?
In writing this article I’ve added Mercedes-Benz-specific info since it seems that M-B (and VW) are most prone to having this P0170 surface along with misfire codes or other fuel trim codes. P0170 means there was a malfunction in the computer’s control of the air:fuel ratio.
What causes Mercedes Benz to run with p0170 and p0173?
If you clear the P0170 and P0173 without fixing the underlying problem those two codes will return in a couple of days. Under certain circumstances such as vacuum leaks, the car may run fine even if the CEL light is on and P0173/P0170 are present. The most common cause of P0170 and P0173 on a Mercedes-Benz is a defective mass-airflow sensor.
