    When was the last time you had a tune up, especially spark plugs and wires, could also be a fuel nozzle on that side, bank 2 refers to the side of the engine it is on, should be the left hand side as you are looking under the hood. could be as simple as a plug wire

    or spark plug. or as complicated as rings or head, valves etc.

    How many miles on eng, and I am assuming it is a 6yl

1 Answer

P0171 and P0174 Left and Right bank lean trouble codes pulled from ECU. Check Engine Light illuminated.


P0171 = system too lean bank 1
P0174 = system too lean bank 2

The fuel/air mixture is too lean for the entire engine. The fuel pump pressure could be too low. The fuel pump pressure regulator could be at fault. There could be an air leak downstream of the MAF sensor. MAF sensor (hot wire type) could be dirty. Check for intake manifold vacuum leaks. The engine coolant temp sensor and/or the intake air temp sensor could be faulty (stuck at full hot mode).

What are these codes and how do I fix them? P0101 P0171 P0174


  • P0101 - Mass Air Flow (MAF) Sensor Performance
  • P0171 - Fuel Trim System Lean Bank 1
  • P0174 - Fuel Trim System Lean Bank 2
  • Would start with the mass air flow sensor the other two codes may have been triggered by the performance of the MAF sensor. Is the vehicle running poorly or have high or low idle?

    Failed OBDII Diagnstic trouble codes P0761 and O1744 What does this mean?


    code P0761-
    Possible causes - Low transmission fluid level
    - Dirty transmission fluid
    - Faulty shift solenoid 3 valve
    - Shift solenoid 3 valve harness or connectors
    - Shift solenoid 3 valve circuit is open or shorted
    P0761 FORD Description Shift solenoid valve 3 is turned ON or OFF by the Transmission Control Module (TCM) in response to signals sent from the park/neutral position (PNP) switch, vehicle speed and Engine Control Module (ECM) (throttle opening). Gears will then be shifted to the optimum position. When is the code detected? The P0761 code is detected when the ECM has detected a mechanical fault with the solenoid energized, valve stuck off code O1744- is not a code these are the ones I have found that come close

    2003 Ford Ranger 4x4 extended cab- diagnostics checked and got these codes- P0171, P0174, P0300, P0316. Can you tell me what they mean?


    P0171------ system too lean bank#1
    Po174------ system too lean bank#2
    For these 2 codes, try cleaning the maf sensor (mass air flow), that is mounted in the big black hose that goes from the air filter housing to the throttle plate, if it is dirty, that will cause those 02 sensors to send a signal to the computor to lean the air fuel mixture. If cleaning it doesn't work, the sensors will probably need changing.
    P0300---- Random/multiple cylinder misfire
    P0316---- Cylinder misfire at start up---- first 100 revolutions.
    On those 2 codes, you have to do some testing to find out why there is a misfire.
    Possible causes:
    dirty/malfunctioning injectors
    weak coil pack
    fowling spark plugs/wires
    Low fuel pressure

    Diagonostic trouble codes reported p0171 p0174 p0302 2001 Taurus, only reports P0171


    P0171 is system too lean bank 1, P0174 is too lean bank 2, and 302 is misfire bank 1. Look for vacuum leaks. If you don't find them, put a vacuum gage on it can check. The P0171 is almost always a vacuum leak. If not other possibilities are front O2 sensor is too old and should be replaced (if mileage is greater than 100k then replace). Try injector cleaner. Misfires are usually bad spark plugs, but could possibly be caused by insufficient fuel. I've never had a car of mine in bad enough shape to have that error.
