Ford F-150 - 1997-2003 :: Check Engine Light Just Came On / Lean On Banks 1 And 2
May 28, 2013
99 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.

My F150 5.4 V8 is running to lean on both banks according to my code reader. I have replaced the fuel filter cleaned up the air filter and I am about to put in seafoam in the gas tank to clean out the jets and carb. I thought fuel pump but have never had to deal with this before. I just bought the truck last thursday. Also my gas gauge is stuk at empty and the low fuel light is on ....

I 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.

I have a 2000 Ranger, with a 4.0 V6, 4X4, with 175,000 miles and it still runs great except the check engine light is on and it is saying that both banks are lean. I put in new plugs, all 3 O2 sensors, cleaned the MAF and checked for vacuum leaks, all to no avail...

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?

My 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.

I 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.

Need to identify this part? I believe this part is causing my check engine light to continually come on, due to worn out connectors (I.e. Vacuum leak)!

I have a 1997 ford f 150 with a 4.2 ltr v6 the check engine light came on so i took it to autozone and had the code pulled. They told me that the o2 sensor bank2 sensor 1 which is before the converter had a slow response so i checked the wiring and bought the o2 sensor. They told me bank 2 is the passenger side but well i changed the1st sensor on the passenger side and reset the code and drove the truck about 130 miles . and the light came back on. After reading a few posts. I think they told me wrong is the drivers side bank 2 or is the passenger side bank 2 ...

I 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.

My 2001 F-150 4.6L was hesitating around 1500 RPM and the check engine light was on, dealer said the oxygen sensors needed to be cleaned. Had the work done and the problem still exists, the check engine light intermittently came on. I tried 89 octane fuel and the check engine light is off and the engine runs smoothly. I'm just a weekend mechanic and can do mostly basic stuff but the only time I've come across something like this is when I accidentally put 87 octane in my bike.

So I have been having some troubles with my 2003 F150 4.6L ... Truck has been running rough and the check engine light was on so I decided to get the codes read and I got back P0302 and P0304, which from what I understand is a misfire on cylinders 3 & 4. At the same time I got Ford to do a little diagnostic and this is what they wrote for me:
"The connector for the number 2 coil is broken and will not stay plugged on to the coil and the number 2 coil is not working / replaced the wire for the coil still running rough removed the coil and plug. the plug was very badly fuel soaked started the vehicle to see if there was spark at the plug. OK. Suspect either a injector issue or a compression issue cleaned the plug seems better. "
So of course they quoted me for the works. They say I should replace the coils, plugs, and injectors??? I am pretty mechanically inclined and think I could change these things myself since I am on a budget. One tech told me is that the plugs can seize in these engines often and could scrap the whole thing??? Seems a little weird. If that happens though what could I do?

Ive got a question for all you code readers out there. My dreaded check engine light has been on for about a month. I bought a code reader recently and checked it out. Two codes come up; PO401 and PO446. What these mean. My book says "Exhaust Gas Recirc. Flow Insufficient Detected" and " Evaporative Emission Control System Vent Control Circuit Malfunction". Which sensors, location on vehicle, etc..... this is a 97 5.4L Expedition.

My girlfriend has a 2002 F-150 with the 4.6 V8 and I was going to change the spark plugs for her. She said it started running rough and it threw a code and check engine light. She took it for a scan and they told her the number 5 plug was mis-firing. I'm fairly handy and bought a set of the recommended Motorcraft plugs from Rock Auto, AGSF32PM. It also matched the number in the owners manual so I thought I was pretty safe.
Funny thing, when I took the old ones out, they were AGSF22WM's instead. My thinking is they are a colder plug than the supposedly original equipment, but I don't think they've been changed before. They looked well used but the color was good. The truck has about 135K on it.
Long story short, and to get to the question(s), Would there be any reason the factory would have put a different plug in the engine than what is listed? Am I asking for trouble going with a hotter plug than what's been in there (pinging or timing retardation/loss of power)? Am I just overthinking the whole thing and need to put it back together and drive it?

I was driving along today and my Check Engine light came on. I stopped at the nearest Advance Auto to have them pull the code and it came up with the P0420, Catalyst Efficiency Below Threshold (Bank 1). I asked what could cause this and they mentioned that the fuel that was put in could be causing it. They didn't mention any other possible causes. Any others? I'm thinking it could be the fuel because the last gas station that I stopped at and filled up at is one that I never go to, and maybe just got a bad batch of fuel.

I own a 1998 ford f150 4.6l triton v8. I was leaving my house to go on a snowboarding trip about three weeks ago it was a rather warm wet day and all of the sudden my check engine light began to flash. I immediately pulled over and restarted my truck, once it was started again it was solid.
I turned around and started driving towards home. I get a small amount of feedback from my speakers and usually it's a smooth whizzing sound but as i accelerated the sound began to stutter rather than remain smooth. after about 5 minutes of driving this went away and the check engine light remained on.
so today I went out it's also a wet day and it's raining quite a lot. on my way into town everything seemed okay. then on my way home the check engine light began to flash again and the feedback from the speakers became choppy again.
I would also like to mention my battery light is on but it was on prior to the first time this happened. I'm just wondering if the belt could be loose or slipping due to the wet weather?

I have a problem nobody can figure out. My check engine light is on. Took it to Advance to have it scanned; came backwith Code 1226, Brake warning light ground short ( not concerned that at this time); Code P1285, cylinder head over temperature; and P1299, engine overheating (this repeated 4 times).
Now for the symptoms: Truck start and runs good, except with engine light on, runs about 4 miles, then the temperature gauge goes all way up, oil light come on (But oil pressure gauge is OK), Have loss power, and heater has no heat. I shut key off, restart, runs perfect, gauges OK, heater OK.
