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.
Yaris/Scion & Vitz :: 2000 Echo Check Engine Light On / Code P0171
First owner, 192000 miles. Check engine light came on during last winter, I put fuel injector cleaner with gas and it went away for a while. It came back on, if i reset, I can drive for about 50 miles before it comes back on line. Also, may be two or three times a week, when moving after a stop, the vehicle stalls, i have to take the feet of the gas pedal and give gas again.
I called up the dealer asking for fuel filter and fuel injector parts prices. Fuel filter is in the gas tank and not meant to be replaced. The fuel injector I was told 4 x $155 each. For diagnostics they need $100
See attached, I was able to clean sensor 1. I could not unscrew sensor 2, the screw is rusted, plus there is no room to get a longer screw driver and turn.
Lexus - RX300 :: 2000 - Check Engine Light Code P0171 Bank 1 Too Lean
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.
Ford F-150 (2009-2014) :: Intermittent Check Engine Light Due To Same Code Every Time - P0171
For the last few months my truck has been throwing an intermittent check engine light due to the same code every time - P0171. The dealer has allegedly checked everything and has given me the "We have done all we can do" speech. Lead tech even suggested that since today's fuels have alcohol in them, that a check engine light would be normal. The truck has been in the shop 3 times with no success or even remote possibility of what the problem could be.
The check engine light has since gone from intermittent to constant and comes back on after 5 drive cycles after clearing with an OBD2 scanner. Also, I'm now getting a P0174 code.
Personally, I think they're trying to blow me off because I'm a few months and about 2k miles away from being out of CPO warranty.
Truck is a 2013 F150 Super crew 2wd 5.0 with about 45k miles.
Passat (B6) :: Check Engine Light - Codes P0100 And P0171
Check engine light came on yesterday evening. Advance read the codes as P0100 and P0171. The guy said something that it may be related to the mass air flow sensor. The car seems to run fine.

Toyota - Corolla - Fuel-economy :: 2005 - P0171 Check Engine Code / System Too Lean
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 RepliesPassat (B5) :: 2001 - MIL Light On With DTC Code P0171 Lean System
I have a 2001 Passat 1.8T that has the pesky MIL light on with a DTC code P0171 lean system. I have sent it to the mechanic many times to no avail. What the mechanic did was replacement of the MAF, O2 sensors, checked intake manifold leak as well as exhaust manifold leak. His last attempt was to check for clogged injectors and fuel filter and they were in good condition. He says the ECM is bad. I was able to retrieve freeze frame data as well as live data which shows that the computer is compensating what it thought was lean by having very positive LTFT of 22.6. I don't believe the ECM is bad but cannot be sure. There is one more thing that was not checked by the mechanic is the EGR valve. Could that be the cause of my woes - the lean system?

I recently had some work done on my 2001 VW Passat 1.8T (timing, water pump, major tune up). IT had 72K miles.....
Now I'm getting the following:
Code P0171 Too Lean (Bank 1).
Emission Light turns on / off.
Check engine light comes on and stays on after about 20 miles. Can this be the oxygen sensor?
Passat (B5) :: P0171 Engine Code - Mass Airflow Sensor Failed?
I've been getting this error code recently ("Fuel Trim,Bank1 System too Lean"). I have a Scanguage, which let me get the error code, and I used it to reset the message - it came back about a week later. I took it to a local repair shop after the second time, but as I'd already cleared the message, he couldn't do anything. It came back about a week later, and this time I took the vehicle in as soon as the yellow light showed up (without connecting the Scanguage).
The mechanic said that he found both P0171 and P0172, and that the problem was a loose vacuum hose AND a failing Mass Airlow Sensor. They reattached the hose and cleaned the sensor, but said that the latter fix may not last - the light came back on two days later. I took it in again (this time, checking the codes, and found only P0171) and he said this confirms the problem with the sensor and he'll have to replace it ($280 for the part, plus labor, less a discount on the labor equivalent to the labor he put in to clean the sensor.)

View 2 RepliesFord Excursion :: Check Engine Light Illuminated For Codes P0171 And P0174
Coming home from spring break towing the TT, the Check Engine light illuminates. Seems to be sputtering at idle, but otherwise OK, so we continued home.
Scanner lists the P0171 and P0174 codes. Ok, where to begin? based on internet info, started by cleaning the MAF sensor and throttle body. When I pulled apart the intake, noticed that the grommet which feeds the MAF in the air intake had become separated letting air bypass the MAF. Hence the reason for the codes.
If you get these codes, check the grommet for the wires feeding the MAF in the air intake to make sure it hasn't become separated from the intake. No more codes.

Check engine light is on and my code reader is giving me a P0000 code that is not listed in the Bentley's list of OBD II codes. My nose is telling me it's emissions related as the exhaust smells too rich. And the car is nearly stalling at idle. Suspect #1 is the MAF but the OBD II code does not support this.

What is the meaning or the fault concerning 4608. The above error code was reported on the computer diagnose machine and it referred me to look into the vehicle ownership manual book BUT its rather unfortunate that i could not find that book. So, what to tackle or replace on the engine to enable the check engine lite go off.

Passat (B5) :: Check Engine Light - P0118 Error Code
I got a P0118 error code on my car. Looked up some things and most people were saying change coolant temperature sensor. I changed it 2 days ago and have not had a chance to clear the CEL. Its still on now, guy at Autozone would not clear it, said it was against company policy.
Will this turn off automatically once problem corrects itself? I went to Autozone and had them rescan the error, this time another code poped up P0444, EVAP(Evaporative Emission System)Evaporative Emission Control System Purge Control Valve Circuit Open. What this can be?
