Code P0171


P0171 - System Too Lean Bank 1 Share
1 ' Add Comment Possible causes
- Intake air leaks
- Faulty front heated oxygen sensor
- Ignition misfiring
- Faulty fuel injectors
- Exhaust gas leaks
- Incorrect fuel pressure
- Lack of fuel
- Faulty Mass Air Flow (MAF) sensor
- Incorrect Positive Crankcase Ventilation (PCV) hose connection
What does this mean? Tech notes
If the P0171 is combined with the P0174 code, it's very likely that the problem is caused by an intake leak. If there are no intake leaks, the next step is to replaced the air filter and clean the air flow meter. If the problem persist the front oxygen (O2) sensor may need to be replaced.
What does this mean? When is the code detected?
- Fuel injection system does not operate properly.
- The amount of mixture ratio compensation is too small. (The mixture ratio is too lean.)
Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Excessive Fuel Consumption
P0171 Description
With the Air/Fuel Mixture Ratio Self-Learning Control, the actual mixture ratio can be brought closely to the theoretical mixture ratio based on the mixture ratio feedback signal from the heated oxygen sensors 1. The Engine Control Module (ECM) calculates the necessary compensation to correct the offset between the actual and the theoretical ratios.
In case the amount of the compensation value is extremely large (The actual mixture ratio is too lean.), the ECM judges the condition as the fuel injection system malfunction and light up the Malfunction Indicator Light (MIL) (2 trip detection logic).

How do I adjust air fuel mixture on 1986 Toyota Cressida straight 6 cylinder dohc


Unless your engine has a carburetor, you can't adjust your fuel mixture. That is done by your cars computer. It analyzes your exhaust emissions and adjusts your fuel/air ratio.
Your oxygen sensor(s) may need to be replaced, or there may be a computer glitch causing the problem.

What is the factory setting for the fuel mixture screw on a toyota 1.8 litre 2Y engine


most fuel mixture screws are set initially by turning it all the way in and then backing out 21/2 turns. This should allow start and idle and final adjustment can be done to fine tune it. Check that the idle solenoid is working as it will shut off the idle circuit if it is not

Choke problem


Replace the chock thermostat. When the engine is cold, the choke is in closed position to restrict airflow and give rich fuel mixture to combustion chamber. As engine area warms up, the choke thermostat gradually opens air passage to increase air flow to combustion chamber, resulting in leaner fuel mixture. The choke is in "full open" while the engine is cold, resulting in lean mixture, causing the engine to die unless you add more throttle to increase fuel mixture.

How do I adjust the fuel mixture on the ford 460 efi


The mixture is not adjustable.
You have fuel injectors that are controlled by the computer.
If the check engine light is not on, I would look for a fuel pressure problem or a leaking injector.

My 91 explorer wont pass emissions, Co levels too high and hc levels. Are high as well


have your air/fuel (a/f) ratio checked. high CO level means you have a rich a/f mixture.

rich a/f mixture means there is too much fuel compared to air. this is bad for fuel economy.
lean a/f mixture means there is too much air compared to fuel. this needs immediate attention since this might lead to over compression in the combustion chamber, which develops to total internal engine failure.

Hard starting every morning


really need a little more info. but at first thought sounds like either a cold start sensor if equipped. or a coolant temperature sensor. the cold start sensor squirts fuel directly into the intake upon startup wen the vehicle is cold. the coolant temperature sensor adjust fuel air mixtures based on the temp. of the vehicle. when they go bad they go to default which is usually about 175 degrees. so when the car is cold and the faulty sensor tell the computer that the car is 175 degrees when its not then the computer delivers the wrong fuel air mixture, the mixture as needed when its warm when the car is actually cold and needs a different mixture in order to start more easily.

How do i get more power from my 1975 cadillac eldorado engine ,also shes running too lean so need the mixture screws adjusting,are these in or out also the air filter is new thanks


The air/fuel mixture screws are usually capped off and the adjustment might not be possible, but if the air/fuel mixture screws are exposed then turning them in will lean out the fuel mixture, and turning the air/fuel mixture screws out will en-rich the fuel mixture.

With the engine fully warmed up and at normal idle speed adjust the air/fuel mixture screws one at a time, and turn each air/fuel mixture screw in until the engine just begins to mis-fire, then back out the air/fuel mixture screw one and a half turns to two turns to achieve a smooth idle.

Be certain that the air and fuel filter(s) are not plugged up (there might be a fuel filter inside of the fuel pump as well as the fuel filter/stone at the fuel inlet to the carburetor) and keep in mind that the minimum octane requirement for that engine is 91 octane, and 92 octane is the average octane rating for the premium higher grade fuel, so a bottle of octane booster added to a full tank of fuel will greatly improve the way the engine idles and performs.

That engine should have an electronic HEI (High Energy Ignition) distributor with the large distributor cap and with the ignition coil inside of the top of the distributor cap, and keep the tune-up parts in good condition and replace them when they wear out. The tune parts would consist of the distributor cap, ignition rotor, spark plugs, spark plug wires, and the spark plugs should be gapped at .045 in.

For better performance from your El Dorado a 1 inch spacer under the carburetor will really help a lot if the hood clearance will allow it, and you will need to set the ignition timing to 10 degrees before top dead center, and adjust the accelerator pump on the carburetor for maximun pump efficiency so that as soon as the throttle is opened there is two healthy squirts of fuel from the accelerator pump, and they should squirt as soon as the throttle is opened, and if the throttle can be opened and the accelerator pump does not squirt fuel at the same time as the throttle is opened, then there will be a lag or stumble from the engine on take-off and a severe loss of engine performance. (The accelerator pump must pump fuel into the carburetor at the exact same time as the throttle is opened)

For better performance check the adjustment of the secondary throttle linkage, and let me know if you require assistance with any of the proceedures.

Be sure that the vacuum lines to the EGR valve are correctly routed and that the EGR valve is not operating at idle.

Also, that engine has a plastic timing gear that was used for the camshft timing gear, and I would seriously suggest that it is changed before trying to get any performance from that engine.

Other than those modifications, the engine would need a better camshaft and the catalytic converter removed to increase the performance of that engine.
