BBK Mass Air Meter MAFs Can Be Damaged by the Following

This changes how much voltage can flow through it, which your computer reads and uses to instruct fuel injectors to add more or less fuel accordingly. As a result, a bad mass air flow sensor causes various driveability problems, including a no-start, stalling, lack of power and poor acceleration. This causes the engine computer to miscalculate the amount of injected fuel. The same holds true for the sensing element, so when a ton of air is being drawn in by your ride’s furious pistons, the MAF’s element is being chilled. A contaminated or failed mass air flow sensor cannot measure the amount of air flow correctly. And, as we all know, when you blow on something, it gets cooler. Jet Power-Flow Mass Air Sensor How Mass Air Flow Sensors WorkĪs your engine sucks in fresh air, it needs to flow through the MAF’s bore and over a heated sensing wire or resistor. That being said, we’ll describe how your mass air flow sensor, or “MAF”, works and why a cold air intake won’t do a thing to it. But will a cold air intake really cause damage? The short answer is “no”, and, of course, there’s more to this story than meets the eye. If you are concerned your MAF sensors may be functioning properly, State Street Auto Repair can examine them and determine if they need to be cleaned or replaced.There’s a story floating around that your neighbor down the street installed a cold air intake, and that it immediately destroyed the car’s mass air flow sensor. It’s important to get proper readings from the MAF so that the ECU can do its job maintaining the correct ratio. The most recently reported issues are listed below. However, it's also a good idea to have a mechanic check your vehicle for damage. One problem related to mass air flow sensor has been reported for the 2014 Toyota Tundra. With many MAF sensor problems, the solution may be as simple as cleaning the wires. This time underestimating the amount of airflow instead of overestimating it.Īlthough this will temporarily improve your fuel efficiency, running lean for too long can seriously damage your vehicle. Similar to running rich, the MAF sensor is sending inaccurate information to the PCM. “Running lean” - the opposite of running rich - means your vehicle has too little fuel and too much air in each combustion chamber. Most of the time, the problem can be fixed by cleaning the MAF sensor's wires. When it overestimates the airflow, the PCM releases too much fuel. It can't measure airflow accurately, therefore sending incorrect information to the PCM. These issues can happen when the MAF sensor is damaged or when its wires are coated with dirt. Signs that your vehicle is running rich include:

“Running rich”means there is too much fuel and not enough air in each combustion cylinder. with the oxygen sensors, fuel injectors, fuel pump or mass airflow sensor. If you experience any of these symptoms you should examine your vehicle as soon as possible. Both 2013 Toyota Tacoma Engine Options Remain Problem-free in the Long Run. These issues can create dangerous situations causing accidents and injury. This could happen while speeding up on the highway on-ramp or cruising down a city street. You’ll experience this as poor drivability such as hesitations or sudden jerking motions, particularly during acceleration.

Stalling, jerking, or hesitation during accelerationĪ bad MAF sensor can cause too much fuel to be left in the combustion chamber, creating untimed detonations. The O2 sensor in your vehicle monitors the exhaust gases coming out of the engine The sensors ensure that It is caused by a failure in one of the oxygen sensors heated elements, specifically bank 1 sensor Like all sensors, mass air flow O2 sensor bad - 2003 Toyota Tacoma O2 sensor bad - 2003 Toyota Tacoma. There are 3 key signs that may indicate it’s time to examine your MAF sensor. This causes the engine computer to miscalculate the amount of injected fuel, causing additional damage to your engine. A contaminated or failed mass air flow sensor cannot measure the amount of air flow correctly. 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.
