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.
