What does code p0174 mean on mass air flow sensor?
Most likely the fuel trim would increase depending on the actual problem present. A code P0174 may mean that one or more of the following has happened: •The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of “oiled” air filters can cause the MAF to become dirty if the filter is over-oiled.
What does p0171 and po174 mean?
A continual low voltage reading indicates a lean fuel mixture, too much oxygen. The optimal ratio is 14.7:1 (air:fuel). When your powertrain/engine control module receives a reading that indicates there’s too much oxygen and the ratio is incorrect, it sends an error code P0171 or P0174.
What does dirty mass air flow sensor code mean?
A common cause for lean condition codes is simply a dirty Mass Air Flow Sensor. Since I have been testing MAF sensors, I thought I should bring up this information.
What does lean fault code p0171 mean on a car?
Your car or truck has either a P0171, P0174 lean fault code or both stored in the pc, these codes derive from Oxygen Sensor (O-2) readings. A lean code or codes suggest that there surely is too-much air in the exhaust.
