For the same reason, the automatic transmission shifting pattern may also change. The heat generated by the hot film is reduced as the intake air flows around it. The more air, the greater the heat loss. At the same time I started hearing this whooshing sound when accelerating. . I checked the codes and it reads p0101 - Mass Flow Operating Outside of Range.
The performance of my car is the same as always including gas consumption - 23 milesgal. So you should chech it on our car models. Thanks for all the help gents. My E500 has 106K on it and this is the first real issue I have had. Thank you, John Sprinter Store A division of Upscale Automotive, Inc.
Ive been checking the Pending codes every few days and it just popped up this evening - p0101. Return the thing to them and get a genuine bosch from someplace like autohausaz. I reset it a few times. Symptoms: The engine computer uses the mass air flow sensor signal to determine how much fuel to inject. I took out the air filter, blew it out, ordered a clean one, put the old back in. Left me stranded, would not start, all I had to do was unplug it. I removed it cleaned it with carb cleaner then took a little screw driver and pushed down on the round metal piece on the bottom.
What does fuel trim meanI have researched the forum and some have mentioned to clean the mot valve with carb cleaner. . It gets stuck at times. They disappear under the cowling that Hi all Im new here and just recently purchased a 2003 c230K with 85000 kms 50000 miles on it. I don't even use olives any more. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing. I cleared the code again and drove home from auto parts store.
May be gumming it up. I reset the code and some time later it came back on again with the same code. They found it was the seal on the attenuator baffle is that the turbo resonator? Im going to do this tomorrow. Bud has worked on other mercedes I owned. They displace too much alchohol. It consists of a hot film that is supplied with electric current from the Engine Control Module. This problem is common in many European vehicles, e.
Thanks, Keith Keith, Not all error codes clear right away. . The intake boot must be inspected for cracks and rips. You did not say what year your van was. To whom did you entrust your steed? I have replaced the sensor and cleared the code but it comes back on again. There is no mercedes-specific code even though the scanner claims to be able to show them if they exist.
I read the code and it comes back as a p0101 Mass or Vol air Flow A circuit RangePerformance. When the car is accelerated, the throttle valve opens and allows more air to flow into the engine. If this does not fix my problem what should I replace nextWould Well I did a little research today and found some thing called a purge valve. When your car's 'Mercedes-Benz Sprinter P0101 Check Engine' light comes on, it's usually accompanied by a sinking feeling in the pit of your stomach. The mass air flow can be tested with a scan tool that displays the live data. In the first photo, you can see a cracked intake boot.
My car sometimes seems to have tugging feeling to it at times almost like a misfire. See the photo of a clogged up mass airflow sensor below. One of the symptoms of a leaking intake gasket is the engine running rough when started cold. This one is for a 2004-2006. While this site lists what each of the codes are the list does not tell you what the actual cause is just a general Hey all update. I think that would leave a film that attracts dust and grime. Examples of what can cause the code P0101 Often the code P0101 is caused by a vacuum leaks.
