p071/p0174/p1131/p1151 codes what does it mean?

it could be anything, but mostly a oxygen sensor going bad, that cured mine, have the codes pulled, they won't pass smog that way :(

P0171 = bank #1 air/fuel ratio too lean
P0174 = bank #2 air/fuel ratio too lean
P1131 = bank #1 is adding more fuel to correct for an overly lean condition
P1151 = bank #2 is adding more fuel to correct for an overly lean condition
DO NOT LISTEN TO ANYBODY, IF THEY TRY TO TELL YOU TO REPLACE ANY SENSORS, BEFORE THOSE CODES ARE DIAGNOSED!!!!
You need to have a mechanic diagnose this concern with a proper scan tool that has access to live data. Information that is especially useful is the freeze frame data (the values of all the sensor readings when the codes were set). This means that he can actually "see" what is going on with your engine electronic control system, NOT those cheesy code readers that only display the code, which is about as good as trying to read Chinese, if you don't have a clue to it's meaning!!! Based on those codes, it tells me you have a vacuum leak somewhere. If it's the 4.0L OHV V6 engine, I can tell you that they commonly leak vacuum from the upper-to-lower intake gaskets. The reason for this, is because the gaskets on that particular engine are made out of thin paper that tend to squish through. The fuel injector rail is "sandwiched" between the upper and lower manifolds by the said paper gaskets. The gaskets themselves are not expensive at all. The labour to replace them will depend on who you take your vehicle to have them replaced. Also check for improperly seated or cracked PCV hoses, they can cause vacuum leaks as well. A dirty MAF (mass air flow) sensor can cause the codes you listed, but it is less likely. DO NOT replace the O2 sensors, or EGR valve as others are advising you to do. They obviously don't have a clue as to what the cause of your problem is.

I am no mechanic, but I have a friend who is one. According to him - any time that the Check Engine light is on, it should not be ignored. With the proper diagnostic equipment your vehicle will flash a code which will indicate just where the problem is. He says that if you ignore the light for too long - eventually the computer in the vehicle will suffer an overload and quit. Then - you not only will have to replace what caused the light to go on in the first place, but you may well have to also replace the computer for the engine-!!

i own a repair shop,and it could have a sensor going bad on it that's making it do this,you can take it to any auto zone and have them, scan it to see if it does have any trouble codes in it,its free,and it will tell you what it is maybe,some of those, the check engine light would come on,and there wouldn't be anything wrong with them at all ,but id at least have them scan it,and see if it is any bad sensors on it,good luck i hope this help,s.

Take your vehicle to Autozone and ask them to read your code, the check engine light can be any number of things. My mother in laws is on now becasue the EGR valve is stuck (1996 Explorer 5.0), i pulled it, cleaned it and the light went off, and in 2 weeks it came back on again with the same code....

almost any self sustaining save provides you with a loose estimate. or you will possibly be able to desire to fork out approximately 60 to 80 funds to purchase your own diagnostic tester. The examine engine gentle might desire to be considered one of one hundred issues. extra advantageous get it checked quicker somewhat than later until eventually now that's going to become something worse.

I have the SAME problem but I took into the shop and they told me the circuit has a short and it won't go off. Maybe it should be a recall thing but oh well cause I have the same car.

Most common self-healing problem, the light comes on and then goes off is because you forgot to tighten the gas cap when you filled up.

many answers the o2 sensor is where i would start.it could be as simple as a tune up.it misses just a little and drops compression the light comes on have it checked if they cant find anything usually the can still turn off the light//
