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
View 5 RepliesGolf 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.
View 9 RepliesFord 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.
View 1 RepliesGolf IV / Jetta IV :: Check Engine Light Came On / P0135 Code For Sensor Heater Circuit
I have a 2002 Jetta 1.8t. My check engine light came on and it gave me the code P0135 sensor heater circuit. Bank 1 Sensor 1. We bought a new 02 sensor and replaced it. We definitely bought the right one too. Cleared the codes. After a little driving the CEL came back on with the same code P0135. What is wrong and how I can fix this?

View 9 RepliesGolf IV / Jetta IV :: 2000 - Coolant Gone - Speedometer Fault Code Came On
This morning, I wanted to drive to work, but all of my coolant was gone. In the last couple of weeks, I had some errors with my speedometer and had it replaced a week ago, which did not fix my problem (the P0722 sometimes still came up).
Could it be that my coolant leaked over the last weeks and somehow messed with my speedometer, or are those most likely independent errors?
My car is a 2000 Jetta VR6 and at this point I don't want to put too much into it any more. If you need more input, let me know.
Sonata NF (2006-10) :: ESC OFF And Code P0102 After Replacing MAF
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?

Replace coil pack?
Swap fuel injectors and recheck?
Golf IV R32 :: CEL Code P0103 / MAF Circuit High
About two weeks ago I purchased an intake from a member here on vortex. I installed it, drove the R a few times, and ended up getting a CEL right afterwards for P0103 (maf circuit high). Does this have anything to do with the intake install? Car runs absolutely fine.. no weird issues. Never heard of an intake causing a code like that. Cleared it.. it came back.
View 4 RepliesGolf IV / Jetta IV :: 2000 GLX - Intermittent Start And Stall / Pending Code P0321
My wife drove the car to work, and it ran good. She got a check engine light, but it was not on when I got home from work. I started the car and it idled fine for a couple of minutes and then it stalled. I check the codes and there was nothing locked in. There was a pending coding P0321. I am not sure what a pending code is, but I assume not enough to trigger the check engine light.
After work each night this week I tried troubleshooting but I have not gotten anything accomplished. Each night the car would start fine but if I turned it off it would not start until many tries if at all. It turns over strong but won't start. I drove it around the neighborhood today and it stalled and wouldn't restart.
The fuel pump primes. When the car won't start the fuel pump relay clicks constantly. Is this normal? I replaced the fuel filter because it has been 50k miles. Is the crank shaft sensor the problem? I hate to throw money at parts that aren't the problem when I can't get a code to trip the check engine light.
Golf IV / Jetta IV :: 2000 - P1296 Code / Hard Start And Rough Idle
Having trouble with my '00 Jetta 2.0 A/T w/ 98K miles. Had the water pump replaced @ a year ago (for the 2nd time, the 1st replacement died after <15K miles.) The car has had issues with rough idle when started, especially with a cold engine, since before the 2nd water pump. I've replaced the coil pack, thermostat, and coolant temperature sensor in the recent past in addition to the water pump & timing belt.
The gas mileage sucks, and when it's idling rough it doesn't "idle up", & will stall if the gas pedal is pressed with 30 secs. of starting. Otherwise it seems to run fine. The coolant temp. sensor was replaced after a CEL indicating it was bad. The CEL went off after it was replaced, but it's now throwing a P1296 Cooling System Malfunction. I have noticed the temperature gauge fluctuates instead of staying around the "middle" since the 2nd water pump replacement, and will run "colder" in colder weather. Since spring is here, the temp. gauge stays around "normal", or the middle.
Some research online says thermostat OR coolant temperature sensor. Since the gauge registers normal now, I'm leaning towards a bad temp. sensor...?
Does the hard start/rough idle and the cooling system malfunction CEL could be related?
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.
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.

View 1 RepliesBuick - 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 :: CEL Is On For P0116 Engine Coolant Temp Circuit / Range Or Performance
My CEL is on for P0116 Engine Coolant temp circuit, range or performance problem. I replaced the CTS, thermostat, and did a complete coolant flush/replacement last November. Car worked well over the winter no issues. Last week when the CEL came on it gave me P0301 and P0440 as well. I did a reset and the lights stayed off for the week. Then P0116 came back. Is it possible that the CTS is bad again? I measured the resistance on the CTS and hot it is about 300 ohms and cold is 2.45k ohms.
View 8 RepliesBuick - 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?
