Passat (B5) :: CEL Codes P0102 And P1137?
Jul 29, 2006
So my check engine light came on (2000 Passat 1.8T) and I have one of the generic code readers and got this:
1. P0102
Powertrain: Mass Air Flow (MAF) Sensor Circuit Low Frequency
2. P1137
Powertrain: HO2S Bank 1 Sensor 2 Lean System or Low Voltage
Now last time I had the car in they said I needed to have my throttle cleaned, but I just didn't have the time then. Could this be the reason or am I looking at bad sensors? It's weird, because the car isn't really driving any differently. I have had one side effect though, my turn signals won't come on and the hazard lights will come on, but not always. All the interior lights, headlights, brake lights are working fine.

I am getting the following trouble codes:
P0342 cam position sensor A bank 1 Ckt Low Input
P0102 MAF or VAF A Ckt Low Input
The accessory belt moves when I try to start it, but my timing belt stays still, but is kind of tight/very little slack.
It died on the highway, was in gear and it just lost power.

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.

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.

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.

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?

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

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.

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?

Where to go at this point. I've had like three different shops tell me my cel is throwing no code. I have reset the battery, the gas lid is shut tight. Just a regular stock 99 passat 1.8t with 177k on it.

Can dealership diagnostic tools read ABS/ASR fault codes, or if those codes are even stored?

I just got a 2000 V6 Passat Wagon. The CEL light was on when I got it though I bought it knowing this. The battery was bad when I got it and I replaced it. After installing the new battery . . .. . starting worked only intermittently. It got worse and at one point I had to hold the key to the start position for about 5 seconds before the starter would even engage. Now it won't start at all. I pulled the codes (shown below) when I first got it but did not give it much credence . . . I wanted to clear the codes and drive it and re-look at the codes. . . . but I have not been able to drive it.
Other observances. . .. not sure if they are related to the car not starting:
Windows, sunroof do not roll up/down while electronic locks work. The driver side window was down when I got it and I read somewhere on this forum to use the key to raise it. . .. it worked. Alarm does not work. Radio works. . . . I found it odd that though the battery was taken out for more than 12 hrs. . . . The radio code was not required. Dome light works intermittently.
I have checked every fuse and they are all good.

Alright so my check engine light had came on today and i got home and scanned it and got 2 codes which were ... P0B33 AND ALSO P1136
What codes are these ? and what is causing them to give me a CEL ? and how could i fix the problem ?

So one day when I was driving, the CEL comes on, and then I go to autozone to get my free diagnosis. I got codes: P0441 and P0171
My engine is running fine and everything else seems to be in order. However, I have to get a new canister purge valve and new oxygen sensors, in order to be in the clear.
For the Oxygen sensors, I have AN IDEA of where they're located; somewhere underneath the car, by the catalytic converter (the converter is in between the two connectors, apparently). I have yet to do this and would like some opinions on what to do for it.
For the Canister Purge Valve, I have no clue where to look. I pop open the hood and I notice a diagram with labels. Great, but there are just too many other pieces to look at...I do not know if it is visible as soon as I pop open the hood, or if I have to dig deeper, or even if I have to remove the fancy plastic thing that covers the engine.

Does this mean i need new injectors? wiring harness? whats the deal here?

Codes P0491 and P0492 ... The Air pump works, so what's the problem? Perhaps the combo valve? If so how do I check this?
