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??
View 2 RepliesSo, 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.
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.
View 4 RepliesSo 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?

123k miles on it
UM NA tune
carbonio CAI
TT cams

My check engine light keeps coming on sporadically and giving me a PO101 error code...then I'll reset it after making sure my MPG hasn't dipped a significant amount (which is my "concrete" way of gauging if it's performance is impaired) and it'll come on 1-600 miles later. There's no consistency in environment or conditions that are triggering this sensor, at least it's not obvious to me. I finally looked under the hood at the filter and it's a little dirty, but not nearly dark enough for it to be the problem.
View 4 RepliesCODE 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 Replies"VSC OFF" light came on the other day. I took my RX350 to the dealer. The dealer said Heater Element sensor is bad. They didnot have this part in stock. I googled this part. Nothing comes up under that search. I took it to Autozone and the code came up as Mass Air flow sensor. Are both of these same thing?
View 7 RepliesNeed 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.
View 5 RepliesI 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 6 RepliesI'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?
View 1 RepliesI 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?
View 3 RepliesI 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..
View 9 RepliesMy check engine light is on. I got the code pulled at Advance Auto Parts. It is P0107 - MAP Sensor Circuit Low Input. I wanted to test the MAP sensor to see if it is bad. I couldn't find anything online that was Santa Fe or even Hyundai specific as far as testing procedures go. I know you can test the power wire, the ground wire, and the signal wire, from what I could tell from other places I've looked. I got 5ish volts from the power wire and 12ish volts on the ground wire, which is what I understand they should be. I don't have a vacuum pump at the moment, but testing the signal wire with no vacuum I got about 0.02 volts. From what I've read online, it should be around 5 volts, but I wasn't sure if all MAP sensors work the same way. Whether I'm doing this correctly and whether they think the sensor is bad?
View 5 RepliesThe MIL light came on and I noticed the shifting P-D or P-R was hard. Checked the Transmission Fluid and noticed it was low. Topped it up, but still MIL is on and shifting hard still. I bought a OBD2 Scanner and it returns P0707 "Transmission Range Sensor Circuit Low Input". Should I try clearing the DTC? It's a drag because it's my wife's car and she's driving mine.
View 1 RepliesCheck 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.
View 15 Replies2004 Sport Trac V6. Been having hard shifting and P0715: Input/Turbine Speed Sensor Circuit. Cleared the codes and still returns.
From my searches, readings and looking at the parts diagram. On the newer 5 speeds the sensor is the one on the inside of the tranny. This requires taking the entire tranny apart? Is there an external connector for the sensor that I can check or clean first? Replace this sensor. I know the older ones were mounted on top of the tranny. I think this one is mounted on the inside though.
I've been getting this error code recently ("Fuel Trim,Bank1 System too Lean"). I have a Scanguage, which let me get the error code, and I used it to reset the message - it came back about a week later. I took it to a local repair shop after the second time, but as I'd already cleared the message, he couldn't do anything. It came back about a week later, and this time I took the vehicle in as soon as the yellow light showed up (without connecting the Scanguage).
The mechanic said that he found both P0171 and P0172, and that the problem was a loose vacuum hose AND a failing Mass Airlow Sensor. They reattached the hose and cleaned the sensor, but said that the latter fix may not last - the light came back on two days later. I took it in again (this time, checking the codes, and found only P0171) and he said this confirms the problem with the sensor and he'll have to replace it ($280 for the part, plus labor, less a discount on the labor equivalent to the labor he put in to clean the sensor.)
B5.5 GLX 4Motion ... My Car has no Power. Idles rough. Take off is slow. I can stomp it to the floor but the RPM needle barely moves.
Mechanic says I have many codes going off but thinks its the MAF. Already spent a bundle (misdiagnosed or ripped off) on other non related stuff that was supposed to fix this problem.
Mechanic says 90% sure but part is non return able. Need to know where to get the MAF cheap and quickly. Also part number or other identifying information so I don't get the wrong one.
My engine is in trouble. A few weeks ago, my check engine light came on. The diagnostics revealed that my Mass Airflow Sensor was done for. I replaced it, and everything was working fine for a week. Then a couple of days ago, my Electronic Power Control (EPC) light came on. The car is really dragging. It have to gun it to make it go above 60 MPH. It's become scary to drive on highways. Are the two issues potentially connected?
View 1 RepliesI have a 1996 Ford Explorer Eddie Bauer Edition 5.0, the check engine light is on and my code reader gives P0161 and P0155 both stating that the O2 heater circuit sensor is bad. I replaced all 4 of the O2 sensors in the truck, cleared the codes but they still keep coming back. I have tried for a few days now to find something online similar to this but have had no luck. I am not sure what else to do.
