Santa FE SM (2001-06) :: Engine Stalling / Idle Very Low - Code P0102
Dec 29, 2014
Trying to get my daughters Santa Fe going. Engine stalling. Idles very slow. 2001 model with 2.4 engine, auto trans.
Code P0102 is active. Cleared with scan tool and it comes right back.
Replaced the MAF and no change.
Checked the intake for leaks / vacuum leaks and none found.
Checked for debris up-stream from MAF and all is clear.
Air filter is clean and dry.
Checked harness plug and found the pin 5 has 4.6 volts on it from PCM. This is the signal wire from MAF to PCM. 4.6 volts is KOEO.
IS THIS NORMAL OR IS PCM BAD ??? All other pins / voltages on harness plug are normal.

I have a 2001 santafe with a 4 cyl The code 102 was up so I replaced the mass air flow censer . I go on a test drive and the light stays off , but when I go to re start it again the light come on and stays on, with the same code. The only strange thing is the idle will raise for a min then drop down to almost a stall.

My coworker is giving me a clean 2001 Santa Fe with 151000 miles. It was running fine then all of the sudden it lost power but was able to stutter home. I went to check it out it started fine but idled a little rough. When I revved the engine it rose to about 2500rpm and stuttered then stalled. Kind of like it was rich and choking out. It then had difficulty restarting.

2001 jetta 2.0 VW guys a while back I was pulling a code saying that the air temp sensor circuit was low I believe it was P0112 so I replaced the maf with a bwd maf. Said it was for the car. Was fine for a day but now it has a P0102 code and the epc stays on (rough idle) what could be wrong ? Is it because the car hasn't learned the new sensor yet because I've only drove 10km or do I have a faulty sensor. BTW replacing the maf fixed the P0112 code

I bought the car 3 years ago 2003 2.4L Hyundai Santa fe , I have driven it around 200 miles ( to and from shops ), I am having an issue now where once the car is warmed up ( post 15 mins ) It will idle really low * almost stalling * and oil pressure light will flicker, If I hold the brake and get it to almost 800 - 1k RPM it goes off and driving is not an issue *no knock*. I just got it driving for the 1st time in the past year, and drove it for about 45 mins in stop an go traffic, Temp light was all the way to cold, once stopped in stop and go traffic it would go up half way, as soon as I could get above 50mph it would slowly work itself all the way to the bottom?

Looking for a picture/location etc of where the crank position sensor is in the engine compartment? It seems to be a common issue where the engine stalls during driving and you pull over and are able to restart the vehicle and go on about your business.
My 02 has over 160k in miles and so am believing this part is going out according to what I've read here. My problem before was somehow the 2wire plug to the alternator worked it's way off and got that taken care of and so now while my wife is driving, it'll occasionally stall. Did a load test on the battery and it's good. Didn't check the charging system but not sure it needs to be tested.
By the way, have ran the diagnostics with the actron pocket obdII and no error codes came up and all looked good scrolling through everything.

so i just bought my '06 sonata 2.4 lt 4 cyl and it had problems with idling when i plugged into the computer i got a p0101 error code saying there was an air flow problem... took it to the dealer since it is still under warranty and for $100 they told me it was my mass air flow sensor and it would be 4 days and $370 more to replace.
I was able to buy the part from napa and replaced the old one (very simple process) and at the direction of the dealer i was told to disconnect my battery for 15 or so minutes to clear the computer data.
When i powered everything back up the car idles and runs fine but i am now getting a check engine light with p0102 lower voltage than expected from the mass airflow sensor AND a new light popped on "ESC OFF" the button will not turn it back on and i cant think of anything I did would have turned it on?

I keep having the P0102 (MAF Circuit Low) code come up. I've replaced the MAF twice already. I also have the P0113 (Intake Air Temp Sensor) which has been replaced as well. Could the breather hose coming off the Intake Air Duct leading to the oil cooler cause this.

I have an 2004 Santa Fe and im having some Mass Air Flow Sensor problems but I dont know what's wrong. My engine light came on for the second time after awhile. And I got it checked for the code and of course it was my sensor again. The first time I just giggled it around and the light went off. I did the same thing today with giggling it again went off. So I feel like it might be a loose connection but I really hope it isn't failing because im pretty sure that's uber expensive to fix.

So the check engine sign came up on my car and using the OBD it tells me the error is P0113. After googling the information, it looks like I have an issue with IAT sensor.
I opened the air filter and what I believe what could be the sensor and there was nothing clogging up, so I'm assuming the sensor needs to be replaced
Question is where is the IAT sensor located and how do I dis-assemble it so I can replace it. Is it the piece that is located just before the air filter?

Check engine light came on and stayed on today. Engine lost almost all power so I guess I was in "limp home mode". CEL ODB-II code was P2138 according to AutoZone.
Accelerator position sensor malfunction
Probable causes:
1. Open or short circuit condition
2. Poor electrical connection
3. Failed APS.
After turning off the vehicle, it seems fine at least in town but the check engine light is still on. This is the first "problem" with the vehicle and it's at about 98K.

I just joined the forum mainly to care of my dads 2001 Hyundai Santa Fe but also I got a check engine light on my way home from work last night.
From last night I saw that oil was all over the timing belt. Today I inspected it with a Coworker and his OBD II reader.
Error Code was P0455, EVAP - Evaporative Emission Control System Leak Detected (gross leak).
Now the oil leak is stronger since the oil spills is on hood (inside hood). I will make a picture tonight when I get home.
I personal think it's leaking from a tube/ valve on top of the timing belt (picture will show more tonight). Thinking of cleaning the timing belt area, then drive a little around or leave it in idle to spot where the leak is from.
Common issue? I googled around but since P0455 is a common issue (on my 9-2x as well) I couldn't find anything about this I am also limited from my search since I am currently at my work PC incl. strong firewall.
I will see if google let me find a picture...

Once warmed up, while sitting at a stop in Drive, there is what feels like an engine stumble every so often. Good guess is every 45-60 seconds, so it only happens once, maybe twice at long stops. There is a sudden change in pitch the engine, and the car - for lack of a better term - shudders. The thing I have noticed is that when it does this there is no indication anything has happened with the tachometer - RPMs hold perfectly steady. Additionally, there is no shudder when sitting in park or neutral, only drive.
I initially thought it might be an ignition fault, so when I replaced the balance shaft belt I also replaced the crank sensor. No change in behavior. I did some googling, which suggested the issue might be related to the EGR not closing properly. I changed all the vacuum hoses and removed the switching solenoid to test - it seems to be doing its job. I have not removed or inspected the EGR valve itself. However, because there is no symptom in engine speed and the sensation doesn't happen in park or neutral and only happens when warm, I am starting to suspect the transmission itself is the culprit - I can imagine if the torque converter quickly engaged and disengaged - and a little power made it to the wheels - the same result would happen.
There is nothing else odd about the engine or transmission. No codes. Runs like a top. Transmission always shifts perfectly. Fluid was changed two years ago, about 15,000 miles. What came out looked good as well. I'm okay with replacing EGR components, but I don't want to throw money at the problem unnecessarily. Maybe try driving around with the EGR vacuum hose pinched off or disconnected?

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.

So today i got my first check engine in the .:R. I was merging onto the freeway and i shifted into third rather enthusiastically (didn't redline in 2nd but i was probably at 6k rpm) and put it into 3rd gave it the gas and the tires squealed and I got the traction control light. Has me a little worried since the traction control light didn't go off afterwards. Got off the freeway and pulled into a parking lot and turned it off for a minute and when i started back up I got the check engine light also. Went to schmucks and pulled the codes and the only code I was able to pull up was P0102 MAF circuit low. I highly doubt my traction control light has anything to do with the MAF circuit. I notice when in 1st and 2nd gear (can't really tell about beyond 2nd because there is too much road noise) there is a slight whine. I cleared the codes and the check engine came back but the traction control light never went off.

I have a 2001 Regal GS with 105K. It starts, idles and runs fine if I drive it like a Grandpa, but if I try to accelerate even 1/3 or more throttle, it surges and misses. It keeps giving a P0102 (Mass Air Flow A Circuit Low), sometimes less than a minute from resetting it, and other times after 5-10 minutes of driving. I've tried 5 MAF's, two of which were new, and one from a known good running L67 motor. Plugs are new and wires are good. The power and ground wire of the connector test good, but I'm not able to test the signal wire. I've also checked over all vacuum lines and hoses, and pressure tested the exhaust for a plugged cat. I even tried another TPS.

I have a 2005 Santa Fe with the 3.5 with 112000 miles on it. I had the engine light come on with the code P0302 cyl #2 misfire, I got spark plugs, plug wires to do a tune up on it. I changed all of it and got it back together, started it up and it still had a miss to it. I then took the front spark plugs out and did a compression test on it. #2 was at 85, #4 was at 120, and #6 was at 160. I couldn't check the back cyls because I had already put the intake back on. I then did a wet test, and all the cyls came up to 160. So this tell me that the piston rings are bad in #2 and going bad in #4. I have kept all the oil changes up and up to this point I haven't had any trouble with it. Having this problem with there 3.5?

My engine doesn't run smoothly (like a misfire) when accelerating at hwy speeds, especially when the outside temp is above 20 degrees... the warmer the temps are, the worse it is.
I have a code P0431 - "warm up cat efficiency below threshold (Bank 2)"
Is it an O2 sensor problem, and if so, which one is it and what is the Hyundai p/n for the sensor? Bank 2 is in the front, correct?

Check engine light on, car stalled once. Pulling code p0320 "Engine Speed Input Circuit Malfunction." Tachometer works intermittently. Where do I start?
