Mazda3 :: 2009 - Check Engine Light / PO101 Error Code For Mass Air Flow
Aug 22, 2011
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.

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??

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.

I am far from home. Taking a road trip. Day 2 out of 6. My check engine light came on, so I just pulled over. All fluids were fine. Found some place to read the code:
P2757 TCC pressure control Sol Ckt Perf / Stuck off
The guy said it was something to do with trans.

"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?

I am having a hard time getting the low EGR flow check engine code to clear. The EGR valve and tube from the exhaust manifold were replaced, the wiring harness verified, the passage channel between the EGR valve and the intake manifold cleaned out...but the check engine light remains... what to try next?

I was going to look into getting a replacement EGR valve from AutoZone, which I did. After installing the valve and on my way to reset the check engine light, it went away and has not come back.

I have an 01 Explorer Sportrac with a 4.0, 105,000 milles. Got the check engine light with the EGR low flow code. I get this code about once a year and a new DPFE usually takes care of it. I get the sensor from Advanced Auto which explains the short life I am guessing. Last time i replaced the sensor the light came back on a couple weeks later.
After highway driving smoke starts pouring freon under the hood, passenger side, but by the time I get the hood opened its done. Cant tell where it is coming from. Could a faulty DPFE cause the smoke or do you think the EGR valve may be sticking? I was going to try a Ford DPFE this time but I hate to just throw parts at it. Where do the smoke is coming out of, air filter box????? cant see anything else over there related to the EGR system......

Not too terribly long ago I got assistance on identifying and fixing an engine misfire on my 2009 Accent. I assumed was directly connected has cropped up again - a P0497 Low Purge Flow error has come up on the car.
We recently replaced the purge flow valve, and everything seems to be running fine - there is no visible cause for the error, and I've even tried making sure I get the fuel cap as tight as possible.
The code is not popping up constantly - this is only the second time it's come up since the misfire was fixed(without obvious symptoms I always clear a code once just to make sure it wasn't a computer glitch), and the first time it popped up on it's own was the day after I fixed the misfire. Need to know what to check to find out what's wrong and, of course, how much priority I should place on fixing this issue.

A few days ago my "Check VSC" warning came on along with the check engine and traction lights being on. I left my car in a parking garage for a week when I was on vacation and the lights came on once I started the car after getting back from my trip.
I have had the "Check VSC" warning before and I fixed it by replacing my gas cap. My gas cap seems fine this time around so I got my codes scanned and the only one that came up was P0300. Having this issue with the 2007 Lexus GS 350? I still feel like it's my gas cap because I bought a cheap replacement last time around.

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.

My check engine light was throwing the code P1121 for the coolant flow valve. Toyota replaced it under a warranty enhancement (I have 134k on it), and since then my mpgs have gone from 46 to 50.
My AC is working much better now, too. My theory is that the valve can be in a semi-failure mode for a long time before throwing a code. Now that My coolant is flowing the way that it should, heat is being dissipated more efficiently.

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.

2003 1.8t passat wagon. 50k miles... The check engine light came on today. Oil and engine temp are fine. Can most shops plug in and diagnose? Can I get one of those code readers at Advanced Auto parts to read the error code?

What is the meaning or the fault concerning 4608. The above error code was reported on the computer diagnose machine and it referred me to look into the vehicle ownership manual book BUT its rather unfortunate that i could not find that book. So, what to tackle or replace on the engine to enable the check engine lite go off.

I got a P0118 error code on my car. Looked up some things and most people were saying change coolant temperature sensor. I changed it 2 days ago and have not had a chance to clear the CEL. Its still on now, guy at Autozone would not clear it, said it was against company policy.
Will this turn off automatically once problem corrects itself? I went to Autozone and had them rescan the error, this time another code poped up P0444, EVAP(Evaporative Emission System)Evaporative Emission Control System Purge Control Valve Circuit Open. What this can be?

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.

Currently I haven't been tweaking anything to my car after driving to go and home I left to go get something to eat and after driving for a few min out of nowhere the engine light, brake and abs comes up. So I freak out a pull over to the nearest gas station and turn my engine off for 2 min and turn it back on and this time only the engine light come up. So I drove to autozone to get it scan and error p0500 comes up. Which means short circuit, vss and poor electricity something I am not exact but is it serious? Like I am freaking out right now.

I have a CEL on my 2007 Avalon so I decided to take it to Autozone to get a scan. Error code P0015 was returned. This code has to do with B Camshaft Position, Timing Over Retarded (Bank 1). I've done a little research and I've read that this could possibly from a dirty screen on the Oil Control Valve, the OCV itself, or the Cam Position Sensor. Before replacing parts, what I would like to do first is to check/clean the screen on the OCV. Secondly, I would like to swap the Cam Position Sensor to a different bank and see if the other bank throws an error. If the other bank throws an error, then I know the sensor is bad and needs to be replaced. With this said, I am having trouble locating the OCV and CPS. Where the valve and sensor is located. A diagram would be useful.

I got a 2012 Hyundai Accent SE manual 112000 mostly highway miles. For a month now I am getting the MIL on and P2191 code (System too lean at higher load bank1) after erasing the code it appeared again in 3-4 days. I replaced air filter check all valves and vacuum in air flow, changed to premium gas. Pipe that connected to the valve from EVAP system looks not damaged and valve works as intended. While changing spark plugs I noticed that all of them were quite charred. I am thinking to replace both O2 up/down stream sensors. Which not OEM sensors would be the best match for my Accent?

I recently bought a 2007 Hyundai Sonata Limited from a private seller. This car has been perfect for the few weeks I've had it. Now, my check engine light came up and the error code "P0660 Intake Manifold Tuning Valve Control Circuit / Open Bank 1" popped up. I'm not really sure what piece to look for, or which connectors to check.
