Santa FE SM (2001-06) :: CEL On - Codes P0401 And P0401p
Oct 8, 2014
CEL has been on for a few months, emissions testing came up so we read the codes (P0401 & p0401p) . We took it to the mechanic we always go to, a local one and they ran a full diagnostic and they said there were no leaks and no build up. Everything checked out fine and all they could suggest was replacing the Solenoid (Don't get me started on that) they said they were baffled (a wee bit worrying). So we did that and 20 minutes later the light was back on . In fact, every time we reset the code it comes on 20 minutes later.
The car is due back for Emissions in a month since it failed.

My truck, the aforementioned 01 f150 5.4 has been running fine but has had the codes p0401 and p1740. I know what they both mean I just haven't fixed them yet. Today I went to move my truck and it wouldnt start. It turned over fine and would hit some but wouldn't start. Would the tcc solenoid be the cause of that? Also the reason my egr is throwing is because there is a line that is not connected but I have no clue where it connects to... Where is the best place to get diagrams for the egr system.

EGR insufficient flow. EGR valve was pretty bad looking seemed a bit sticky when opened so I replaced it along with gasket. Reset the computer but check engine light came back on code p0401 again. I know you can test by pinching the yellow striped hose at the throttle body to see if the solenoid is bad. The engine will stumble a bit when you pinch it closed, or so I am told. However when I pinch the hose, nothing happens. I do notice that the car does idle kind of roughly.

Originally started with a p0302 code, and it cleared. CEL came back on with codes p1131 and P0401. First time with an 8 plug 4 cylinder. Truck has 263000 miles, and still original (metal) DPFE sensor. 1996 ranger 2.3L.....

The Explorer ran just fine last week, until I tried to clear a chronic (months) "Check Engine" light. Initially the only 2 codes were pertaining to the DPFE sensor and Cylinder #1 misfire. I found an aftermarket rubber hose from the DPFE that had rotted off. I replaced the rubber hose, and I replaced the #1 spark plug and wire. Instead of simply clearing the codes and turning off the "Check Engine" light, it now shakes to the point where it's barely drivable. 57 mph seems to be the "sweet spot" where the shaking is the worst, but it will also shake under heavy acceleration, and when driving uphill at freeway speeds. Taking your foot off the gas seems to decrease the shaking somewhat. The weather had been unusually cold (for South Texas), and as the weather has warmed-up, the shaking seems to have diminished, so there may be a connection between the shaking and the temperature.
OBD-II Trouble Code: P0301 Cylinder 1 One Misfire Detected
OBD-II Trouble Code: P0401 Insufficient EGR Flow
I have a lot of questions, but do not want to cloud the 1st post of the thread with information that may be irrelevant, so I'll leave it at that. This is my work vehicle and I'm in the middle of a job and am worried that I may be causing permanent damage to the vehicle by driving it. I know I can change-out the DPFE sensor and the ICM, but as they are both non-returnable parts, I don't want to spend the money without good reason.

My camry 2000 recently the engine light's on and the codes are P0446 and P0401
P0401:The PCM has determined that there is insufficient flow in the exhaust gas recirculation system.
P0446: The PCM has determined that a malfunction exits in the electrical circuit fo the vent control in the evaporative emission control system.

I have a 2010 Toyota RAV4. In February 2014 at 34,600 miles when the car was 46 months old I had the EVAP (charcoal) canister and filter replaced for $1,300. Error codes were P043, P0401 and P0402. Recently I had the following check engine error codes appear (P043E & F, P2401, P2402 & P2419) and was told by my mechanic that the car basically had the same problem. I am now at about 50,000 miles. I don't believe this type of problem is very common; also I think that the EVAP should continue functioning for a lot longer than ~4 years and now ~1.5 years. How likely is it that I got a "bad" original EVAP charcoal canister & filter and then the replacement was also "bad"? Might there be something else that is defective that is causing the EVAP canister to go bad? I don't generally top off the gas tank when filling up.

This is what I have done I have 5.4 168,000 on motor . I have codes p0401 p0701 p0704 and some others .I can run truck for about 15min and it starts to lose power .I can't go over 1500 rpm . I have changed egr cleaned throttle body checked for vacum leaks changed the dpfe . new plugs . I have had a misfire code on number 1 but that code has stopped . I have put new fuel filter .I have a cheap scanner I use and it probably won't give me what I want also I changed down stream 02 sensors .

My 97 F150 4.6 4x4 threw a P0302 and P0401 the other day, I traced the miss fire to a loose injector plug. I reset the codes last weekend, I got in the truck and went to the Dump and to town to pick some stuff up. It threw the EGR code again, so this morning I did a little checking on the EGR I cranked the truck and disconnected the FPR vacuum line and hooked it to the EGR valve and the truck died down but didn't completely die.
Now the green line that went to the EGR valve felt like it had a slight bit of pressure coming from it. Is this normal? I did pull the white feed line from the EGR Regulator and it had good vacuum.
The regulator also makes a humming sound when you cut the truck off. Ill be pulling the alternator this weekend due to it going out last night, while I'm in there if Ive got to pull the throttle body id rather do it while I'm elbow deep in it. So does it sound more like a Clogged Throttle body or a Faulty sensor?

I have a 2006 Santa Fe with the 3.5l, AWD, 5 speed auto, and 65,000 miles. Its a daily drive. Out of the blue it won't start. It cranks, but it won't start. The battery is strong and it has 1/2 tank of gas. I figured my code reader would solve the mystery, but it's doesn't produce any error codes. With no codes I don't even know where to begin.

1999 F-250 V10 .... Truck was running perfectly fine except for a random high idle sometimes when put into park but if I gave it a good rev it would drop back down to normal. I assumed it was a dirty IAC or something and figured I'd get around to it later kinda deal. I also had a coolant leak from what I thought was the intake manifold to head gasket on the drivers side right in the front where the upper radiator hose meets the intake manifold so i added water here and there no issues.
One night I need to pull a trailer and didn't have the wiring set up for it in the back so I stopped at advance auto and bought one of those kits that plugs into your brake wiring harness and then plugs into the trailer. I tested it in the parking lot with the trailer and it was all sorts of messed up. My reverse lights stayed on my brake lights didn't work either etc. Turns out it was for the wrong years but plugs matched up coincidentally. I returned the kit and drove home just fine.
Next morning on my way to work truck started misfiring like crazy idle was bouncing all over the place lack of power etc. I took it to advance again after work even though no check engine light came on I still pulled 2 codes. P0300 which is multiple random misfire (no specific bank) and a P0401 which is an EGR Insufficient Flow code. I took it by a local shop I get my oil down at and they told me it was probably the fuel pump that they go bad in these trucks alot.
So I replaced the fuel pump and the fuel filter. Nothing changed so I thought maybe that coolant leak had dripped down to the plugs or possibly the intake gasket was getting worse and leaking coolant into the air flow ports since it was thought to already be a problem. So i pulled everything off the top and firgured id go through it all why I had it apart. I replaced the intake gasket but noticed when i took it apart that it wasnt the gasket that the head it self had a small pin hole leak in the very front where the coolant fed into below that upper neck that bolts to the intake manifold. I patched it with jb weld/ quick steel/ and rtv. Yes I know it wont last but just for the time being until I figure out the main issue. Replaced the plugs with motocraft plugs checked all my coils for grime and corrosion or what not and they all seemed fine and cleaner than expected. replaced the gaskets and threw it all back together. I also cleaned out the EGR and IAC with air and brake cleaner etc.
Blew all my lines out with air and everything seemed fine. I also replaced my DPFE sensor. Started it up ran fine at idle for like 5 min no coolant leaks or anything so I thought I was golden then about 500 ft through the neighborhood on a test drive the exact same misfire came back doing the same thing with the idle etc. I'm going to check my fuses tonight but I'm starting to think that maybe when I plugged in that wrong wire adapter for the trailer that I may have screwed up something with the PCM. Only because the lights were all out of wack and literally the next morning I started having these issues. I'm lost if its not a fuse. I would really hate to buy a PCM and not need it especially after all the parts I've bought and not needed already.
The vacuum lines all seemed fine and intact as well with no cracks or leaks.

My '04 santa fe 3.5 v6 gls/lx, 79k miles, gas, auto, check light has just come on while I was driving a less than 10 mile journey. How can I check what is wrong. Do I need some sort of diagnostic code checker. Do any national outlets check it for free (Pep Boys or Auto Zone, etc).
Just 5 days ago (about 50 miles only) I had timing belt, water pump, plugs and leads replaced, brakes checked and lubes flushed; BUT not at above dealers. I would rather know what the code is saying before I go back to the shop who carried out the work.

Left my 2002 SF 2.4 with someone to replace clutch. Calls me after the job to say it doesn't run!
Codes P0100 and P0340.
Maf is new. I had a Cam sensor in stock. Nil fix.
Have changed out recently;
Fuel Pump
Coil packs
CPS
MAF
and just now, the Cam sensor.
It starts right up then shuts off, does not slowly sputter and die.
I asked him to go over the wires and connectors. He could have stressed a cable while pulling the tranny. I do have the old MAF that I could try, but doubtful it would fail at the same time as a clutch job. Now wishing I had done the clutch myself!

Often, when starting it will run rough and throw different misfire codes. Most of the time it smooths out in short order (a minute or less). When it doesn't smooth out quickly, it smooths out when I clear the code. Also, rarely it will start very hard. I have to wimd out the starter pretty good to get it to start. All that I have done is cleaned the MAF sensor.

2004 Santa Fe 2.7L V6 2WD ... Car was running fine, filled it with gas, and upon starting, heard a backfire into the intake manifold. It coded for a Cylinder 3 misfire so I had plugs and wires changed.
Now...The car starts, idles rough, accelerates sluggishly, and running rough any time it was around 2000 RPM. After I changed the plugs, it started bucking a little and stalls when I take off in the morning.
Coded and it's reading 7 codes, but some are duplicates:
-P0274 Cylinder 5 Injector Control High
-P0305 Cylinder 5 Misfire
-P0102 MAF or VAF A Circuit Low Input
-P0050 H02S Bank 2 Sen 1 Heater Circuit
-P0030 HO2S Bank 1 Sen 1 Heater Circuit
-P0274 Cylinder 5 Injector Control High (Shows Twice)
-P0102 MAF or VAF A Circuit Low Input (Shows Twice)
After having a backfire and then cylinder misfire...replacing the plugs and wires.

Still having problems with my 2.4l 2002 santa fe. At stand still the MAF readings are within range. At 2000rpm it reads 9.3 gm/s. the info I have says it should be between 7.89-9.83.
When driving along at 50mph, 5th gear, engine speed 2000rpm it reads approx. 25.0 gm/s. at 3000rpm it reads 48 gm/s. Is the MAF sensor faulty?
It is now not running very well with fault codes P0171(fuel system to lean) That code comes up whilst driving at speed. I also get P0172(fuel system to rich). I got that one whilst driving slowly in a car park.

My car is misfiring, codes p0171 and p0300 come up on the code reader. It idles rough and has very little power. I have checked my exhaust , it is not plugged. When I unplug coil #2 while idling there is no change as to the engine performance so I switched the coils around with no difference when coil is unplugged on cylinder #2. I have changed the plugs, there is power to the coil, all plugs are firing and when removed plugs 2 and 3 are wet with fuel indicating I am getting fuel and fire. I have replaced the cam sensor with no change.

I have a 2004 santa fe with the 2.7L v6. I was driving and then it started to sputter and then stalled. I tried to restart, but the the engine would crank but no start. I came back to it about half hour later it started up as if there was no problem, and then after a 10 minute ride it stalled and did the same thing.I got it home and scanned it, came up with a couple misfire codes, a crank sensor code, and improper segment timing code ( I never heard of improper segment timing ). Also after fuel fill ups it never wants to start or stay running. I researched the fill up problem and found the purge canister valve to be bad. I haven't changed the purge valve yet, would that have anything to do with the stalling? If the crank sensor was bad, would it start later if it sat for a while. With my experiences when a crank sensor goes bad, the vehicle wont restart at all.

I am getting two codes, p0171 and p0401. Both point to something with the fuel are mixture I believe. My problem is that I can not figure out what the problem is. As far as I can tell there is not a vacuum leak. My MAF sensor looks clean and close to brand new. The codes come on and the car seems to want to jump. It does not stall, just starts to bounce a little until I let off the gas. And it does not do it until the car is warmed up. 2001 Santa Fe .....

I am having a problem with my 2003 Santa Fe I have taken it to have the check engine light codes read and I have a code for the crankshaft position sensor, random misfires, something with gear 2 and 3 (not sure what it was exactly) it makes a loud noise when in 1st and 2nd gear when I shift out of 2nd the noise gets less and less until its gone and then does not come back until the car sits for a little while and cools down. Its running rough and does not have any power when accelerating. I had the timing belt changed a few weeks ago and it started running funny shortly after. I don't think the guy that did the timing belt knew what he was doing because I had to have someone go behind him and tighten the pulley.

I have had a check engine light go on and off with P0700 and P0741 but since the flush day 3 it hasnt come back on and it was chucking with rpm doing small jumps... but now it does it in the mornings after sitting all night after a few chucks its fine for the rest of the day til the next day no check engine light so far, but transmission flush has worked a lot not as bad as before the flush.. So what else could be causing it? Its a 2006 hyundai santa fe with 274,000 kms.
