Prius (Gen 1) :: Lean Condition In Bank 1, Code
I have a 2002 prius with 130,000 miles on her, and so far so good except for a small problem for the last three months, I get an intermittent P0171 code. I know it means Lean Condition in Bank 1. However, I can run the car for weeks without it coming on. If I go full throttle getting onto the highway for example it may come on, but even then its not all the time. Not sure why only full throttle. But if I drive her gently, I will never see the CEL at all.
Fuel economy is around the usual for me at 46-49 mpg with average speeds of 75-85 mph. I don't think its vacuum related.
Prius (2010-12) :: 2013 - Engine Hesitates At Highway Speeds?
I just got my new 2013 Persona Prius on Saturday. I haven't put too many miles on it (under 200) but I'm noticed that a feel a stuttering or hesitation when I reach highway speeds. Typically about 65 -70mph. I can't think of a better way to describe this but it feels like the when driving a manual transmission, when you need to shift to the high gear? That kind of stuttering feeling. I'm sure that it's not the same problem but it feels like that. Once I go faster, the feeling stops. Or slower. But going between 65 to 70, it's the same feeling.

I picked up a really cheap Hyundai Elantra 2005 that the kid that owned it really beat up on. Right now I am trying to sort out the issues so that it can become my daily driver for the next few years.
Second issue, The check engine light is on and it is popping up a P0171 generic engine running too lean code. The car looses power sometimes and I can smell gas in the car. I have a friend that is going to be loaning me his MAC code reader so that I can see if it is one of the O2 sensors and if so which one tomorrow.
Prius (2010-12) :: Towing And Speeds Over 85 Mph Can Result In Severe Engine Damage
My owners manual for my 2010 Prius says speeds over 85mph can result in severe engine damage. It also states you should not pull any type of trailer, but I have seen a few Prius's with trailer hitches but I would not try it.

2000... I have a code P0171 bank 1 too lean. My question is does this exclude anything that will effect both banks? If it was MAF sensor or fuel filter would it set code and say banks 1 and 2 running too lean? In which MAF sensor ohms out correctly. I cannot view fuel trim files. I have looked for a vacuum leak with no luck. I got some cigars to try to smoke it to see if there is any vacuum leaks. Trying to narrowing what i need to checks.

I have a 2006 Chevy Trailblazer LS/LT 4.2 liter 2wd. I have been trying to get it smoged, but can't clear the code. P0171 - Lean Bank 1.
I've been having a parts throwing contest with it, but it has been winning and my wallet is losing.
I have changed the air filter, cleaned the MAF sensor, changed both O2 sensors, changed the secondary air valve and relay. I've done the carb cleaner spray test around the intake and vacuum lines, with no spikes in RPM.
Most recent try was a couple bottles of Techron concentrate with premium chevron gas.(still waiting to see if the code hits again)
Next steps are checking the intake bolts(to see if they are torqued) and intake gaskets, check for exhaust leaks at the exhaust manifold, and checking the MAP sensor.
Freeze frame data from the most recent hit on the code is below.
***Fuel system 1 - CL***Fuel system 2 - NA***Calc Load(%) - 30.2***ECT(deg c) - 48***STFT B1(%) - 3.9***LTFT B1(%) - 22.7***MAP(kPa) - 33***Eng RPM - 809***Veh speed(km/h) - 0***Spark Adv (deg) - 10.5***IAT(deg c) - 20***MAF (G/s) - 5.82***TPS(%) - 15.3***Air status - NA.
Passat (B5) :: Check Engine Light Came On - Code P0171 / Fuel System For Bank 1 Was Too Lean
We have a 2003 Passat 1.8t. Had the Check engine Light come on. Went down to AutoZone and hookeded up the OBDII reader. Came up with P0171, Fuel System for Bank 1 was too lean. Probable causes:
1. Fuel Pressure of MAF (If Bank 1 & Bank 2 set codes together)
2. O2 Sensor
3. Ignition Misfire
4. Fuel Injector Problem
Car has 60K - has always run well. Wife says she thinks it's running a bit sluggish. I rarely drive the car, but I think she's right. Car is not missing or running rough.
I cleared the code & started the engine; Check Engine Light is off; then looked at the codes and I find a P0171 (Pending). She tells me that the light has been on before & then gone away. So I guess it clears itself, but eventually comes back.
Ford F-150 (2004-2008) :: Rough Idle / Engine Stall Out While In Park - Lean Code
My 04 F150 has started having a rough idle. While in park the engine will stall out with the A/C off. Also when in drive the truck will idle close to 1000rpm's. I had to the fuel filter cleaned and also the MAF sensor cleaned. Also did a vacuum check on it. Pulled the code and it's throwing a Lean Code. What else should I be looking for?

This is the infamous error code many Accent owners might have experienced it. The code refers to "Too lean intake system". People try to replace all kinds of parts like ECM, MAF, O2 Sensor, TPS, Fuel Pump, Fuel Filter, etc. according to my research. I just bought a 2001 Accent and the P2188 light came on. I wrote an email to Hyundai Corp. Asking what would be the most likely part that will cause the (P2188) check engine light to come on.

I have an 05 Toyota corolla, and have the check engine light on, I scanned it at autozone and error code is P0171 - System Too Lean (Bank 1). Which shows following possible causes: Faulty MAF, O2, fuel injectors blockage etc. On recommendation from the guy in autozone, I added fuel additive to clean the fuel line/ injectors. The check engine light went away for 9 months. But it is back on again. Tried putting in fuel additive again but the light remains on.
View 5 RepliesKia - Spectra :: 2009 - Engine Start Racing When Try To Come To A Stop
I drive a 2009 Kia Spectra. Mileage - 89,000. About a year ago, very infrequently, I started noticing that the engine would start racing when I would try to come to a stop. Now, almost every time I start the car, the engine is racing while it is still in park. And when I come to a stop sign or stoplight, the engine races when I put on the brakes. This is NOT an issue with the mat hitting the accelerator. Lately, also, the car is starting to die for no reason when I bring it to a stop. I took this in to a mechanic, they could not find a problem--they cleaned off some cables but the engine was racing when I turned it on to drive home.

View 4 RepliesSanta FE SM (2001-06) :: Engine Racing At Idle And Then Dying At Stop Light
Bought a 2001 from a used car dealership about 2 months ago. A week later it started acting funny. It would often race the rpm's about 2000 when at at stop light and then others times would act like I was out of gas when I would take off. Sputtered and then finally run normally. Then other times it wouldn't start and just crank over and over. After 10-15 times it would fire up and then act like nothing was wrong. It was a total crap shoot whether it would start or not each time.
Took it back to dealership and supposedly their mechanic installed a new fuel pump. Ran like a champ for about another two weeks and then exact same symptoms started showing up.

View 2 RepliesFord Ranger / B-Series :: 2003 - Lean Codes / Jerking At Highway Speeds
I've got a 2003 Ranger 2.3L DOHC, 5 speed, 2WD. It has a check engine light with codes :
P0316-Engine Misfire Detected On Startup
P0704-Clutch Switch Input Circuit Fault
P2195-O2 Sensor Excess Lean Signal Bank 1-Sensor 1
P0171-System Too Lean (Bank 1)
The truck runs fine when coasting or accelerating but when holding a steady light throttle to maintain speed the truck starts bucking and jerking. It's doesn't feel like a misfire, more like a fuel cut out condition. When this happens and you come to a stop, you can smell that the exhaust is very rich coming out of the tailpipe. I've already replaced the upstream O2 sensor and I did a tune up about 15k ago. I'm thinking fuel pump or fuel pressure regulator. I doubt if this is related, but on start up (more so on a cold start up) the A/C compressor clutch kicks in and out 3-5 times and makes a terrible racket.
Prius (2010-12) :: Check Engine And Red Triangle Light Came On - Code P0A7F
My check engine and red triangle light came on. I checked the code and it's a battery issue. The code is P0A7F. I called the dealer and they want me to bring the car in for a check.
I'm afraid it will lead to me replacing the battery. I have about 117,000 miles on the car. They have a service bulletin open on this code but I may have exceeded the 100,000 mile limit.
If I do need to replace the battery are there any improvements I can make in this area?
Prius (2010-12) :: Engine Light Suddenly Get On When Driving - Error Code P0401
I have a Toyota Prius (2010), and the car has run for about 2800000 kilometers. One day when a was driving my Prius the engine light suddenly get on. So I went to a car car mechanic, he checked the car and told me there was an error code (error code: P0401, exhaust problem (exhaust recirculation flow).
So I bought a liquid that I put in the gas tank, the liquid would clean the exhaust pipe, but the engine light was still on. The engine light is usually on at least 2 weeks, then disappear for about 2 days and come back in two weeks…The car is driving normally without any problems.
Prius (2010-12) :: Check Engine Light / Code PO0456 - Entire Gas Tank Needs To Be Replaced
2012 Prius Gen III 38,000 miles, check engine light came on. Drove car to dealer and they came up with error code 0456. The explained that a rodent (I live in a rural area) chewed on a hose which is causing a leak like a bad fuel cap.
To solve this problem they recommend that the entire gas tank needs to be replaced. Does this seem reasonable? It seems to me they are saying that the chewed hose can not be replaced.
