If you own a Dodge Grand Caravan or are thinking about buying one, you may be aware that its production will cease in mid-2020. Therefore, if you like owning a Grand Caravan, you will need to keep your current model running. Fortunately, with a little know-how and some Dodge Grand Caravan auto parts, you can keep it on the road for years to come. Understanding how systems like the mass air flow sensor work can be valuable knowledge.
The Purpose of a Mass Air Flow Sensor
The function of a mass air flow sensor is more or less described by its name. It measures the mass of the air flowing into the engine. This is important because your vehicle needs to know how much fuel to mix with the air. The right mixture causes optimal performance, fuel-efficiency and longevity. The wrong mixture can cause a broad variety of problems.
It achieves this by measuring the electrical resistance of a wire in the air intake. The wire gets heated up by friction from the moving air. The greater the mass of the air flow, the hotter the wire. Metal’s electrical resistance increases when it gets hotter. So, by measuring the resistance, the device can determine how much air is moving through the air intake.
How To Identify Mass AirFlow Sensor Problems
Problems with the MAF sensor are typically very apparent. As mentioned above, the sensor is integral to ensuring the right fuel/air mixture in the engine. Therefore, if it fails, the engine will either run lean or rich. This leads to rough idling, stalling, poor acceleration and more.
Additionally, the check engine light will be set of the MAF system fails. You can check the diagnostic trouble codes using an OBD-II reader.
Double-check your findings using a multimeter. You can check that the sensor has the correct voltage and frequency. The tolerance thresholds are included in your vehicle’s manual.
Fixing a Bad MAF Sensor
Fixing a broken sensor is relatively easy. In most cases, the best fix is to simply replace it. While they are repairable, these Dodge Grand Caravan auto parts are relatively inexpensive.
In some cases, the MAF sensor simply needs to be cleaned. Start by disconnecting the battery then unplugging the MAF sensor. Unfasten the retaining screw and carefully lift the MAF sensor out. Inspect it for any dirt. If there is significant filth, it likely only needs to be cleaned. If not, it probably needs to be replaced.
If the new sensor comes with a complete assembly, you can simply place it back in the original spot and reconnect. If not, you will need to open the sensor casing and replacing the unit.
Maintain Your Dodge Grand Caravan
Maintaining your Dodge Grand Caravan will help you to keep it on the road for longer. You will get to know your vehicle more thoroughly as you work on maintenance and basic repairs. With a few basic tools and some patience, you can achieve a lot. Just start learning and see how much you can do to take care of your vehicle and save money.
