I have a 2001 Ford Ranger 2WD XLT. How many oxygen sensors it has? I bought four (two upstream and two downstream) but my mechanic said there was only one downstream and installed three. However, the check engine light is back on saying "Too Lean." Is it possible that they missed one of them or that all three were simply bad?
View 1 RepliesMy 2000 ranger with the 3.0 is only getting around 10 or 11 mpg. It's got a check engine light on but the scanner just says lean condition. The truck also has a rough idle. I've replaced the fuel pressure regulator and fuel filter.
View 14 Replies99 F250 LD 4x4 w/5.4 - 218k .... Check engine light just came on so I had the trouble codes pulled. 071 and 074 . Lean on banks 1 and 2 . Truck is running fine as far as I can tell. I know it can be o2 sensors, pcv, maf sensor or loose vacuum line somewhere. I just put a new motorcraft pcv valve on before this happened so I rechecked the lines , all seem to be fine. Is there a inexpensive scanner that I can check the o2 sensors without just throwing money at new ones.
View 3 RepliesI bought 04 Lariat (5.4 3v around 100k miles, Roush Off Road side exit exhaust, DWV intake mod, SCT 3015 tuner).
The truck has had a miss on and off for around a month I've changed plugs and tested all the coils. Which cured the problem for around a week, the FPDM had some white stuff on back and soft spot but not ate through. The only Check Engine Lights have been bank 1 to lean (which went away as soon as it came. But yesterday and today I've got bank 2 to lean.
Below is a quick data log pull... The misses is about ready to ship her out if she don't straighten up..
My vehicle is a 98 F150 5.4 ltr Triton. I got a check engine light on and the error is "bank 2, system too lean." I read that this can be caused by a few different things like vacuum leaks or fuel filter and so far I haven't been able to narrow down. It started with occasional shaking at idle and its happening more as time goes. When at idle it often makes a sound like slurping the bottom of a drink with a straw and shakes intermittently. The fuel economy seems to have gone down. Sometimes it seems like it almost dies in idle, but always keeps running. It runs great when I push on the gas.
View 4 RepliesI have a 99 f150 with the 4.2l v6 with a 5 speed 173000 miles. I picked it up not to long ago. When I first got it it had both the P0171 & P0174 lean on bank 1&2 it was also siting for a while. I replaced the fuel filter which was filled with black fuel, also changed the PCV valve, cleaned the MAF sensor, and changed the oil. I cleared the code, drove it for a little bit and the light came back on after 20 miles.
I then proceeded to replace the upper and lower intake manifold gaskets. Upon doing that i noticed that i was missing one of the linkages for the IMRC. I went to the junkyard and pulled off another linkage rod off the same motor. ordered new plastic clips, put the IMRC on cleaned everything up and began putting it back together. I also cleaned the Injectors while i had them out as well and put in new spark plugs and wires.
Put everything back together. code was cleared since the battery was disconnected. drove it and then the engine light came back on again. this time it was only the p0174. so i then both the upstream and downstream O2 sensors on bank 2, reset the code and it came back on again. I'm lost.
I just bought a 99 f150 and the check engine light came on with code p0171,system too lean bank 1. It runs and drives fine but has a strong smell of gas when I shut it off.
View 4 RepliesI recently had some work done on my 2001 1.8t Passat. All new vacuum hoses & camshaft tensioner replaced by VW dealer. Check engine light is coming on and an independent shop near read out a code: Bank 1 mixture adaptation(multi): System too lean.
What does this mean??? And could this relate to these parts being replaced??? Work was done approx 2000 miles ago.
I have had 06 passat with a 2.0 turbo. It been a great car. check engine light has come on with a few codes.
P0171 lean air fuel mixture. P2015, p2008, p0507, p2015, p2008.
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.
View 19 RepliesI 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.
My 2007 Outback has had an off-idle stumble since I bought it a year ago. Otherwise runs well and uses less gas than the 2000 Forester it replaced. I've had a smoke test done, cleaned the throttle body, replaced front oxy sensor, and used a variety of gas treatments. I don't trust the local Subaru dealer to work on my car and my local garage has run out of ideas, but suggested MAF sensor may work. Some days it runs better than others. Occasionally I'll see a check engine light P0171 (lean) or P0420 (cat) but it will go weeks between setting those.
View 9 RepliesWe 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.
My wifes 2007 Santa Fe Limited 3.3 has had a check engine light going on a year now. Car has about 122k on it now. Scanned codes about 6 months ago and had a fuel system lean code. Did some reading and ended up replacing the purge valve. The CEL stayed off til the end of the drive cycle and came right back. I have noticed when you fill the car up there is a real strong smell of gas but the car always starts right up. It now has a P0171 Fuel system too lean (b1) and P2187 Fuel system too lean at idle. Where to start. Don't have much background with hyundai. Also the ESC off light comes on randomly and goes off. Doesn't happen real frequently though.
View 4 RepliesThis 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.
View 3 RepliesI have a 1997 Ford Ranger and my Check Engine Light came on a while back. So I eventually bought a scan tool and I'm only getting one code which is P1443. I've looked at both my Chilton and Haynes Manuals, my Ranger manual itself which is pretty useless for this problem, and I've been searching the internet like crazy.
From the threads I have read here it doesn't seem like a hard problem to fix yourself, and it seems like if you take it in anywhere they will charge you an arm and a leg to work on the EVAP system but it's an affordable do it yourself project.
I just don't know where to begin though, I see people talking about buying the complete set with hoses and the canister and sensor all together but I can't find all these parts. Where do I begin to repair the EVAP system?
Ive got a '94 ranger with the 8 plugs and more often than not while driving and sometimes when it first starts, the cel comes on and immediately I notice a lil rough running and lack of power. Also my milage has dropped since this has started. Plugs, wires, o2 sensors, not to familiar with my gas saver. I love it cause I can just get in it and go. With twice the fuel milage as my bi truck!
View 14 RepliesSo i have a 2000 ford ranger 2wd 4cyl .190k miles. My issue is the motor has a very rough/shaking idle,abs light on,and check engine light on.it also continues to blow fuses to the tail lights and dash, haha
Ive had it since it was at 40k and has been a great truck,although lately i have really neglected it.ive changed the spark plugs and new wires new timing chain. I would d love to start trouble shooting some of this stuff this weekend if the weather holds up.
Im getting an intermittent stumble with a check engine light. I have a 1990 Ranger XLT with a 2.3L 5spd. I pulled the codes 32 41 88. I looked them up but Im not sure what to check next. I have done much searching on several sites but havent found much. OBD-1 eludes me.
32(R)EVP - EGR not responding properly during test - EVP
41System Indicates Lean
88 Loss Of Dual Plug Input Control c ..
What does it all mean??? What would you check next?
My check engine light has come on on my 2003 Ranger 2.3L 4V equipped Ranger. I have a Stinger code reader which shows a trouble code P2004. I havn't been able to find out what this code means.
