· Combustion timing needs to be accurate, or engine damage can occur. If the information isn’t sent to the engine computer, nothing will happen when you try to start the car as a way to prevent damage. Dirty sensors will impact whether your vehicle starts. An example of this is the Mass Air Flow sensor or MAF. The job for this sensor is to let the computer know how much air is in the engine. As …
Since any engine requires the correct air to fuel ratio and ignition timing to start, having a faulty sensor that can''t adjust these symptoms on the fly can cause the engine to not start. Dirty sensors will impact whether your vehicle starts. An example of this is the Mass Air Flow sensor or MAF.
9 Can a mass air flow sensor stop a car from starting? 10 Can a bad mass air flow sensor cause misfire? what happens if I unplug my MAF sensor? If you disconnect the mass airflow sensor, then the car should keep running and still be able to start normally. This means that if your mass airflow sensor dies completely, then your car will stay running and surprisingly the car might run better ...
· The mass air flow sensor monitors air intake as it is mixed with fuel prior to being injected into the motor. This sensor relays vital information to the ECM which uses this to make adjustments to fuel supply to the motor. A dirty or faulty sensor can cause an imbalanced air/fuel load to be supplied to the motor which results in an over fueling ...
· The symptoms of a bad mass air flow sensor include low engine power, poor fuel economy, an engine that won’t start, a check engine light on the dash and a gas smell from the exhaust fumes. A bad mass air flow sensor is often the likely culprit if your car isn’t running as it should.

· Lot more interesting detail can be read , why would a car run better with the mass air flow sensor unplugged? Because either the sensor is reporting incorrect air amount and or air temperature to the ECU. By disconnecting the sensor the ECU switches to limp mode and the car may idle MAF sensor wires can be cleaned and some cannot as the wires are not easily …
People Also Asked, Can you use starting fluid to clean a mass air flow sensor? a good quality carb cleaner works better than the best brake cleaner usually works better than carb cleaner. but the best thing i‘ve found to clean a MAF sensor with is plain old starting use the straw from a can of brake or carb cleaner to get a pin point stream to spray on the sensor elements.

No Comments . No matter what make of European automobile that you drive, your engine will have problems if the mass airflow sensor is on the fritz. Also called the MAF sensor, this …
Can a sensor stop a car from starting? Since any engine requires the correct air to fuel ratio and ignition timing to start, a faulty sensor can cause the engine to not start. Is this true? Faulty sensors can keep your engine from starting, but they are often engineered in to be a safety measure.
· More frequent stops at the gas station; The engine surges at idling ; Other driveability problems; You get diagnostic trouble codes pointing to the MAF sensor; On some vehicle models, the MAF sensor also informs the computer about air intake temperature and engine load (to control some automatic transmission functions). So a bad MAF sensor on these cars can cause an even wider …
· If you unplug the mass air flow sensor the car will start. If you try to plug it in while it''s running the car will die. My car has 90000 miles. My car has an automatic transmission. Recommended Services. Spark Plugs Replacement: : Get a Quote: Mass Airflow Sensor Replacement: : Get a Quote: Jay Safford. Automotive Mechanic. 16 years of experience. This is a ...
If the information isn’t sent to the engine computer, nothing will happen when you try to start the car. Another sensor that will impact whether your vehicle starts is the mass airflow (MAF) sensor.
· As a result, a bad mass air flow sensor causes various driveability problems, including a nostart, stalling, lack of power and poor acceleration. In addition, a faulty mass air flow sensor might cause the Check Engine or Service Engine Soon light to come on.
· Well, the answer to that is no. If you disconnect the mass airflow sensor, then the car should keep running and still be able to start normally. This is because the computer in the car if it does not receive a reading from the mass airflow sensor, will estimate and supply a number that it thinks it is supposed to have.
· Video 3 as Monkey Wrench Mike tries to get a Mercedes CLK320 back on the road! This time he tries a new MAF sensor? Are they all created equal?
· Often if an air filter is not installed properly, or the air filter box is not closed, a piece of debris can get sucked into the mass air flow sensor (see this photo) and cause problems. Sometimes the debris can fall in during the air filter replacement. In this case, the repair is easy. The mass air flow sensor must be cleaned and the air filter must be reinstalled correctly or replaced.
· A Mass Air Flow Sensor costs 100 and 400 while the labor costs 40 to 150. The MAF sensor itself is often quite expensive, as you sometimes have to replace the whole MAF sensor housing. Even the sensor itself can be expensive. Luckily, replacing the MAF sensor is often very easy and done in 10 minutes for most car models.
· "Yes. its a maf sensor (mass air flow sensor) and it will not let it start it will mostly just crank n crank over or start for a min with spiradic idling n shut off" Actually, there is such thing ...
· This can be because the car needs more fuel. If the mass air flow sensor is playing up, then the powertrain control module will not be able to determine the optimal air fuel mix, which in turn causes the engine to suffer and drag. Delayed Acceleration. Another function of the car’s performance that’s likely to suffer under a bad sensor is the acceleration. If fuel cannot reach the engine ...
· Follow These Tricks! 3. Engine idles roughly or halts. These are the bad MAF sensor symptoms that indicate that the sensor is completely out of order. In that case, the car’s computer cannot control the fueltoair ratio because the sensor does not send any information to it. As a result, the engine either halts or idles roughly.
The mass air flow (MAF) sensor, part of your vehicle’s electronic fuel injection system, is responsible for calculating the total amount of air entering the engine. A faulty MAF sensor can cause your vehicle to run too rich or run too lean. You’ll notice if the tailpipes eject black smoke or when the engine runs rough or backfires. You may also notice you’re filling up at the gas station ...
