What causes a p0170 code on a MAF sensor?
Dirty air filter, air filter housing or Mass Air Flow (MAF) sensor, or faulty MAF sensor are common causes for the P0170 code.
What causes a Mercedes Benz to have a p0170 code?
P0170 and P0173 Code Causes The most common cause of P0170 and P0173 on a Mercedes-Benz is a defective mass-airflow sensor. The MAF sensor gets dirty over time triggering the CEL and the two codes.
Why do I keep getting Mercedes Fault codes?
Most of the time these Mercedes-Benz fault codes are caused by a defective Mercedes Mass Air Flow Sensor (MAF) sensor. You can try cleaning the sensor but that doesn’t always work. It is best to replace the sensor. If the codes remain it is possible you have a vacuum leak.
What to do if your oxygen sensor says p0170?
Common misdiagnosis includes bad Oxygen sensors or worn spark plugs. These items are unlikely to fix the P0170/P0173 codes. Always clean or replace the MAF sensor first. First, clean the Mass Air Flow (MAF) sensor. You will need MAF Sensor Cleaner to spray on the sensor.
