CRC 05110 Mass Air Flow Sensor Cleaner - 11 Wt Oz. by CRC

Product Information

Additionally, you might notice a change in the way the engine idles. If the engine doesn’t get enough fuel, the idle becomes rough. However, it can also be rough when there’s too much fuel as the engine becomes flooded. By paying close attention to the normal idle of the vehicle, you can determine when something doesn’t seem right. The problem might start out small at first and become greater as the problem persists. However, for it to be extremely noticeable there would have to be a bunch of other symptoms showing as well. How Often Should the Mass Air Flow Sensor be Cleaned?

With all the problems listed above, you can imagine that the fuel economy might also suffer. If the engine is running rich where too much fuel is burning, you could see a drop in fuel economy. The mass air flow sensor is otherwise referred to as the MAF. It’s part of the car’s electronic fuel injection system. This component is located between the intake manifold on the engine and the air filter. Many modern MAF sensors also have the intake air temperature (IAT) sensor built in.When the MAF sensor becomes contaminated, too much fuel or not enough can find its way into the engine. With this imbalance, the engine becomes harder to start. Depending on what kind of car you drive, you might see a variety of codes. For example, some of the most popular include P0100: MAF circuit malfunction, P0101: MAF circuit range/performance, P0102: MAF circuit low input, P0103: MAF circuit high input and P0104: MAF circuit intermittent.

You shouldn’t have any trouble starting your engine if everything is working the way it should. The combustion chamber uses both air and fuel to start the ignition process. Take the vehicle for a drive to see if it runs better. If you are still experiencing problems, you might need to have the MAF sensor replaced. While many of these performance issues indicate a problem with the MAF, that’s not all that could be causing them. For this reason, it’s important to do a better diagnosis before assuming the issue is the sensor. 5. Reduced Fuel EconomyDigital mass air flow sensors utilize a frequency output, while the analog MAF sensor produces variable voltage output. Both of these are sent to the ECM, where the air-fuel ratio is regulated carefully. With an air-fuel imbalance, you will notice a change in the performance of the car engine. In some ways, it can cause a surging or hesitation as you try to control the vehicle. When it hesitates, the problem is usually an abundance of air. On the other hand, the surging means there is too much fuel.
