Dec 15, 2009· I cannot get it to read higher than at 2,000 rpm. I cleaned the sensor before thich is ese readings and got slight improvements but only slight. Also, my Autoenginuity scanner is not showing any significant readings above lb/min. on the Mass Air Flow reading. The autoenginuity live readings sensor range for the MAF is about 026 lb./min.
Sep 25, 2009· Last week, I put in new air filters at 23,000 miles. After I installed them, it sat in the garage until I drove it the other day for about 8 miles. The check engine light comes on and the car starts to run like crap. Took it to the dealer, and they replaced the mass air flow sensor. Drove it around 40 miles and now no problems.
Oct 15, 2021· Diagnostic trouble code (DTC) P0102 isn’t in every vehicle’s code library, but whenever it appears it means “Mass Air Flow (MAF) Circuit Low.”. The code is set when the ECM/PCM perceives a problem with the mass airflow (MAF) sensor’s performance. The MAF sensor is mounted between the air filter and the throttle body.
Resetting the Mass Air Flow Sensor by Idling the Engine. Turn off the engine and let it cool down if you’ve been driving. Remove the connector with the harness of the sensor. Pull out the air flow sensor and clean it properly. If you need to replace it with a new one, install the new sensor instead of the old MAF sensor.
What Are the Symptoms of a Faulty Mass Air Flow Sensor? Signs of a bad MAF sensor may mimic problems such as low vacuum, low compression, or low fuel pressure due to a bad fuel pump. The most common symptoms of a malfunctioning MAS sensor include: • The engine is hard to start or has trouble turning over. • The engine stalls soon after ...
Oct 07, 2020· If the MAF sensor has issues, the engine may not run smoothly, especially while idling. Poor Fuel Economy: The MAF sensor does not have to fail completely to affect fuel economy. If the ECM errs rich, it may add more fuel than necessary, causing poor fuel economy.
Aug 08, 2019· When the mass airflow sensor has gone bad, you’ll definitely feel it. Here are the most common symptoms of a bad or failing MAF sensor: Idle Issues – Your Jetta may run rich or lean when idling, or it may also idle erratically. A rich condition is when there is not enough air relative to the fuel in the air/fuel mixture.
Sep 12, 2010· hi there im new to the diesel world i have a 2006 ford f250 ,my son got me an [email protected] cold air intake for my birthday so well installed it,then 3 weeks later my engine light comes on so i take it to the dealer and they said it was the mass air flow sensor,they said it had oil on it,my question is is that normal and will it keep happening if i keep the [email …
Jun 22, 2020· The mass air flow (MAF) sensor is an important component which the engine control unit depends on. When the flow of air enters the fuel injection system of the engine, the mass air flow sensor will analyze how much air is flowing in there. It will then relay this information back to the engine control unit.
The most common signs of bad mass air flow sensor (MAF) in MercedesBenz CClass are loss of power or slow acceleration, engine hesitation or jerking during acceleration, erratic idling, misfires, poor exhaust emission values and sometimes black smoke comes out of the tailpipe.
Dec 16, 2017· Quick test to tell if Mass Air Flow Sensor is bad or dirty which could be causing your car or truck to run bad or keep cutting off.
Jan 03, 2009· drove 6 hours at 29 C .The next morning ran truck for 20 min to warm it up and got on the road drove 1/4 of a mile "Engine power is reduced" went to dealer they told me mass air flow sensor they cleaned it tested it worked fine for 2 days ,then did it again weather 25 to 30 c went back they just read codes ...same thing mass air flow sensor . warmed truck up for …
Aug 08, 2019· The mass airflow sensor (commonly abbreviated to MAF) is one of the most important engine management sensors. A bad mass airflow sensor can leave your Volkswagen Tiguan’s engine running rough, or even inoperable.. A MAF sensor measures the density of the air entering the intake manifold.
Mar 01, 2021· A MAF sensor needs to run properly because the ECU needs information about the amount of air in the engine. Fortunately, detecting bad MAF sensor symptoms is not rocket science. Just be alert for these common symptoms: 1. The car runs rich at idling or lean when running. Hotwire MAF sensor is the most commonly used sensor.
The mass air flow sensor or MAF sensor is part of the intake system in MercedesBenz CClass responsible for measuring the amount of air entering the engine. Driving your CClass with a bad MAF sensor can damage the engine, so you must act urgently to avoid more expensive repairs.
Oct 07, 2020· The mass air flow sensor measures the air mass flowing into the engine intake. Measuring air mass is critical in calculating how much fuel to add to achieve the correct airfuel ratio (AFR). The ideal AFR is :1 ( pounds of …
