Golf IV / Jetta IV :: 2000 VW 2.0L - Code P0102 (MAF Circuit Low)

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.

Santa FE SM (2001-06) :: Engine Stalling / Idle Very Low - Code P0102

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.

Golf IV R32 :: CEL Code P0102 MAF Circuit Low - Slight Whine When In 1st And 2nd Gear

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.

Regal :: Surge And Missing If Try To Accelerate Even 1/3 Or More Throttle - MAF Code P0102

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.

Buick - Century :: 1999 - Hesitate During Acceleration / Stalled - Code P0102

1999 buick century custom .. 3100 motor .. 200k+ miles ..

It all Started 2months ago.. once every few weeks my car would hesitate during acceleration (leaving a light for example) but just once.Then started it up one day and it was idling rough..also stalled out twice.

Dropped it off at a shop after hours so he could check it out in the A.M.he calls n says its not acting up at all.

Get the car back and drive it 2 more weeks..then it happens again. Rough idle and hesitating...take it directly to the shop but its acting normal again by the time I get there (starting to feel like im crazy)

So I take things into my own hands... I change air filter, clean MAF and throttle body. Change the plugs and wires.

start it up and it seemed to run better than it ever has.. for about 5mins.I took it for a test drive and it started sputtering and bucking and eventually died to the point of undrivable.

Got towed home.NOW it starts dang near everytime but runs EXTREMELY rough for a few seconds before eventually dying. It will run a bit longer if I unplug the MAF (45seconds maybe) but runs like fecal matter the whole time

I have swapped out the MAF, EGR valve and IAC valve with parts from a 97 century (which runs fine)And nothing seemed to change the condition.

Changed fuel filterchecked fuel pressure with key on (41psi)Also replaced the timing chain and gears (thinking it slipped) but it didnt make a difference.

I pulled codes but all it had was a P0102 (MAF low input)But I think that might be from it being unplugged so many times?

Golf IV / Jetta IV :: 2001 - Code P0102 / Air Temp Sensor Circuit Was Low

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

Ford Excursion :: Code P0102 - Mass Or Airflow Circuit Low Input

CODE P0102 "Mass or Airflow circuit low input" That was the code and upon checking my records prior to storing it for the year. I installed a new IAC,MAF, Fuel Pump and lots of new hoses, PCV, Fuel injection regulator. The Vehicle has only 110K miles. Now here is the clincher, after doing just the fuel pump it ran perfect for at least 25 miles, perfect I say. When I shut if off I got the check engine light, and thus the code which led me to install the other stuff. Now after pondering the matter, seems that it acted in a similar way PRIOR to my doing anything but there was no code previously. Like maybe some strange electrical connection, or something.

Buick - Regal :: 1996 - CEL Code P0306 Cylinder 6 Misfire Plus P0102 Mass Airflow Sensor

Ok, my 1996 Buick Regal is acting up. I got a CEL, which was a P0306 (Cylinder #6 misfire), took the car to my shop, and they diagnosed as a faulty Ignition Control Module. Fast Forward, a day later, the car now has a hard start problem and throwing the same code, plus a P0102 Mass Airflow Sensor.

So my questions are:

1) Could a faulty ICM cause a single cylinder misfire, did they just replaced a random part? I would think a bad ICM would a multiple misfire considering on this car each coil controls 2 cylinders.
2) Are the two codes related? ie fix one, and the other would go away? or are they separate issues?
3) What could be wrong with my car?

This mechanic has been in my family for years, however, I'm not very pleased that a day later, my car seems to have more problems than before. Am I being too harsh?

Sonata NF (2006-10) :: Check Engine Light Won't Go Off After Replacing Flex Pipe

I recently had my 06 Hyundai Sonata 3.3 v6 brought into my local repair shop for a flex pipe replacement and ever since I got it back the check engine light has come on. I brought it back in, they said the 02 sensor needed replacing, replaced it free of charge, got the car back light went back on again and they said this time they put the wrong sensor in so they replaced it, now the light is coming back on again. It seems to go on for a day then go off for a day. I've only had it back for about 3 days so far.

Could this be perhaps the 02 sensor needs to break in or the computer needs time to reset or something like that? What could be causing this issue? Should I wait a couple more days before bringing it back in to have them.

Sonata NF (2006-10) :: Replaced OCV And Still Getting CEL With Code P0011

I have a 2007 GLS. Within the past year I had about 4 or 5 difficult starts. Just recently I got a CEL with cod P0011. I replaced the OCV as that is the usual culprit. Within 6 miles of clearing the CEL, I am still getting the same CEL. I am wondering if the problem is either the wiring harness or the Camshaft Position Sensor.

Sonata NF (2006-10) :: 2007 3.3L V6 With Intermittent Code P0018

2007 with 3.3L at 30k miles (bought new and with regular oil changes) starting throwing p0018's intermittently. No noticeable difference in way the car drives: idle seems fairly normal (only once recently felt the idle briefly stumble at a red light), fuel consumption regular, no power problems. There has been a engine tapping sound at low speeds only heard until the engine warms up after a couple of miles (I'm in Florida, temp is regular in the 70-80's), and the sound is not evident during the start-up, only while accelerating slowly.

On occasion, with hard acceleration, the "ESC 0ff" light comes on, not affected by the ESC off switch, and stays off after one key turn.

Brought to Hyundai dealer who, same day, requested doing an oil/filter change (Firestone had done a change 900 miles/3 months prior) claiming that a wrong oil filter could cause blocked oil galleys. They did the change (and also, no charge, repaired a valve cover leak) and 6 days later called to tell me the car was fine. No mention of the car having been low on oil or evidence of sludging. Also, no mention of whether or not the filter that was replaced was the incorrect filter for the vehicle. (I called Firestone and they claim they regular work with Hyundai to ensure proper filters are used). No mention of why they kept the car for an additional 5 days after the oil change before calling either (except for repairing the valve cover leak with a rocker cover gasket), and although their invoice indicated that they drove the car 5 miles, it was evident from the invoice that the mile in/miles out were the same. I did notice that there was about 2-3 gallons of fuel consumption though when I picked the car up.

6 miles from the dealer after pickup (2 key turns) CEL returns, with same code. I have now driven the car about 100 miles in the last 20 days with the CEl going off and on 4 times now, and each time the same code. I have never had the CEL come on (or go off) while driving, only at start-up. (Longest trip has been 10 miles, top speed 50mph, so a lot of key turns). The longest the CEL has stayed off was for a 30 mile span. The tapping sound mentioned above continues too.

I'm hesitating returning to the dealer. The 10 yr warranty might be a problem for a variety of reasons, and I realise finding the fix for this code could get expensive. But I do want to know what the dealer found out doing their GDS (and via eyes on inspection) and nothing was mentioned on the invoice besides the gasket leak. I'm especially concerned about the timing chain and tensioner.

Is it acceptable to make an appointment with the service manager to find out what they ruled out (and then take that information to a regular mechanic)? Given the problem is regularly intermittent over the last 100 miles, is it still possible that something might be seriously wrong with the engine and damage might be done to the engine by driving it? When I first brought the car to the dealer, they said they couldn't do anything with it because the CEL had gone out. Fortunately, within a mile from the dealer the CEL returned and they took it in. Presently, the light is out again.
