Golf IV R32 :: CEL P0103 Mass Or Volume Air Flow Circuit High Input
Jan 12, 2016
So i got the UM tune done to my car then went and got my TT cams installed. After giving me car the 50 miles to adjust for the cams i get a CEL P0103 Mass or volume air flow circuit high input. Checked the connections around the maf and im noting seeing any broken vac lines or anything out of the ordinary.
Cleaned the maf and cleared the code but the CEL popped back up, got a new maf just because I like spending money on things i dont need and the CEL is still there, low speed or high speed it will pop on.
Is there anything I am missing that could be causing this problem or something i can try other then take to the place that did my cams?
2004 r32
123k miles on it
UM NA tune
carbonio CAI
TT cams
Test pipe and neuspeed cat back exhaust

I cleaned my k&n air filter on my 02 passat 1.8 turbo let it dry oiled it very lightly, and 50 miles later I get a check engine light on, pulled the code 16486 and it says Mass or Volume Air Flow Circ Low Input. Cleared the code put a frame in until I can get it filter. Why that would throw me that code, k&n oil gumming up my sensor??

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.

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.

So, I've got a new toy (FORscan ODBII software) and a new code that isn't turning on the CEL (yet) but also didn't show up in OBDWiz either.
P1100 - Mass Air Flow (MAF) Sensor Circuit Intermittent
I cleared it, drove a few miles, checked again and it's set again.
The little troubleshooting advise window in FORscan says to monitor the MAF voltage while wiggling the MAF harness and see if the voltage goes below 0.23v or above 4.60v. I was unable to manually make that occur, no matter how I tapped on the MAF or wiggled the wiring.
However, in oscilloscope mode, look at this (at idle):
It sure looks like it went below 0.23v here. I have no time tonight to do any research. This is a relatively new MAF (one week old, Delphi unit). I think I'll swap it out for one of my two old OEM MAFs sometime this week. But if any opinion about this, pipe up. I do damned little work with scanners these days, and the tech keeps changing.

I went to my local Autozone today to have a code read and get the freeze frame data. I got a code P0118, Engine Coolant Temperature Circuit High Input. I called the dealer but they are out of stock on the sensor. Would it be a problem to use an after market sensor? I'm just concerned about the quality and accuracy of the sensor.

I have a problem with my sonata NF 2006 the check engine light turn on like 2 days ago and give me the p2128 code say Accelerator pedal Position Circuit - High Input something like that i cheek all the cable off the throttle body to the ecu and i don't see any cable broken how I can check the accelerator pedal sensor? I see in one page a texting the sensor whit a multi miter but was for santa fe and the cable don't have the same colors . I need the accelerator pedal cable diagram and i don't have it ....

Engine light is one for about a month and finally got an ODB II.
Today it reads the error code [b]P0118 which is [b]Engine Coolant Temperature Circuit High Input
The coolant sensor reads 45 C when the key is on "on" position at about 2:30 pm this afternoon and I start the engine about 2 mins the temp jumps to 68 C, are these some logical number?
Does it mean the bad temperature sensor and I need to replace it?

Check engine light is on, this is the code that came up when checked at OReillys, "P0113 Intake Air temperature sensor 1 Circuit high input". Earlier took it to repair shop, he did not give the code, some sensor needs to be changed (don't know if he came up with same code). He had erased the code but it came back on within minutes. Wanted to check if there is any cheaper way to fix this. This is a windstar van.

Need to diagnose an issue with my 2012 GTI its got 39,000 miles its stage 2 Unitronic tune. So I was driving like an idiot coming home one night and i jumped a set of train tracks. Bent my plastics a little and when I cranked my car the next day my CEL was on. I noticed my intake was much noiser than usual. My buddy checked the code and said i needed a new mass air flow sensor. We replaced it and my CEl came back on within 20 minutes of replacing the sensor.

I'm getting a weird code on my engine it's p1298 which is electric load detector circuit high input and I'm also getting 3 misfire codes but the car runs great what can I do to fix these.

I am throwing a code for long term fuel trim being out of whack (code 17560) and I am trying to determine whether the MAF is causing it.
I pulled several redline runs while logging flow rate in vagcom. According to Ross tech's site they suggest that your flow rate should be around 80% of the engines rated horsepower. So approximately 200 g/s. I did several runs and never broke 100 g/s so what I should be seeing or has run into this code before.

What is that called? Mass air flow sensor wiring harness? I google 2011 vw gti MAF wiring harness, and i get nothing, or crap thats almost not related to what im looking for. While I was installing my intake, I accidently cut half of the wire to my MAF located behind the battery. Why I was cutting, dont ask, i was impatient. Anyways, what is it called? I want to replace my MAF and the wiring that leads to it.

I recently picked up a 2000 jetta vr6 for a very good price its a glx I have owned a vr6 before and done timing chains myself on it this one is a glx , I am having 5 fault engine codes on my vagcom they are cam position sensor , knock sensor, secondary injection pump, and mass air flow it ran fine 100 miles yesterday this morning the epc came on then went off and ran bad can these codes all be related or do I have to replace each sensor individually..

Im trying to change my spark plugs in my 2.0T. For some reason I can not figure out how to undo the mass airflow sensor from the connector and the same for the spark plug coils.

I've had two mass air flow sensors burn out in my 05 TDI Passat. Dealer says it's faulty wiring in my vegetable oil conversion. Sensible?

I think I'm getting bad gas mileage on my 03 passat... I don't think it's my imagination...? I'm gonna keep track of how many miles I get next time I fill up, how do I know if I should look into a new MAF sensor?

Oil leak.... I can not locate the MAF sensor in my 2012 gls 2.4l sonata. I followed from the front tube intake through the air box to the throttle body and i do not see one. I also have the service manual and no mention of said sensor!

Cleaning the MAF on the GX460? I have seen videos on youtube but the MAF positioning on the GX460 is a little hard to get to. I am wanting to clean the MAF because I am still experiencing some sluggishness. The vehicle's response had improved after a fuel induction and a spark plug change but it is still sluggish when compared to other GX's I have test drove. It is sort of inconsistent. Sometimes, it drives super smooth and the gears quickly shift other times the gears take forever to upshift and downshift.

Ok so I just replaced my mass air flow sensor about a week ago. My check engine light just came back on and when I scanned it it said mass air flow sensor. What could be causing this to happen again? The codes are P0102, P0440, P0440.
