Getting a New Air Flow Meter: What Are the Things You Have to Consider?

The air that goes inside the engine must be measured to come up with the right air-fuel mixture. This is job is best handled by an air flow meter. This meter sends signals to the engine computer, basically relaying the amount or bulk of air that enters the system. Through this information, the computer is able to adjust and control the drops of fuel that will be injected for combustion and power generation. Unfortunately, this meter can get clogged up with dirt and eventually fail. With a faulty meter, you may notice excessive black smoke coming out of your vehicle and decreased gas mileage. Your vehicle’s performance will also suffer with reduced drivability, loss of power, and running difficulties. A warning light may come on when the meter fails. A diagnostic tool or machine can be used to figure out the problem. Once you’ve confirmed that this part is the trouble-maker, you’ll have to replace this right away.

New vs. remanufactured

Not all airflow meters sold in the market come with 100% brand new components. Some of them are remanufactured. Although remanufactured sensors may use restored components or recycled parts, these are tested to make sure that they function properly. They also come at a much lower price compared to brand-new meters. But, if you want uncompromised quality and performance, you may be more comfortable buying a completely new air flow meter. Look for a meter that matches the specs of your vehicles and one that meets the industry standards.

Stock replacement vs. performance upgrades

Some airflow meters are simply designed as stock replacements. These are designed to have OE-comparable quality and design. If you want better performance and special features, then you should be looking for high-performance airflow meters. These meters are a good option for racing vehicles and high-performance applications. These come with added features and may function better than the stock air flow meter for sale.

Direct fit vs. universal fit

Some airflow meters are designed as a direct fit to specific vehicles. These sensors match the specs of particular vehicles and can be installed more easily. Meanwhile, universal airflow meters can be installed on different vehicles or numerous models. Some of them, however, may require minor modifications. When shopping for a new air flow meter, take note of some product details such as the OE number, terminal, material, color/finish, and blade type to see if it matches the OE specs.

Checking the Air Flow Meter: Some Troubleshooting Tips

The air flow meter helps the engine computer make necessary adjustments. By measuring the bulk of air that gets through the intake system and the engine chambers, the engine computer can come up with the right air-fuel mix. Once the meter fails or becomes defective, engine performance will be hurt badly. The vehicle may idle roughly or even stall frequently. You are likely to encounter a lot of driving problems. However, before you pull the plug on this sensor, you have to be sure that this is really the one that’s causing trouble. Here’s how:

Note: Use a vehicle manual to locate the meter and to help you with other components that have to be checked.

Difficulty level: Moderate

Tool to use:

  • Voltmeter

Step 1: Look for dirt or rust on the air flow meter, which comes in a “T” shape. The sensor wires are found at the lower half of the sensor. See if the wires are still intact or if they’re plugged with dirt.

Step 2: Use a voltmeter to measure the resistance. Set this tool to ohms, and then gauge the resistance between the E2 and THA terminals. One of the leads of the voltmeter must go to the THA terminal, while the other must be placed on the E2 terminal. It should read zero (0) or near this number (proceed to the next step). Otherwise, the meter can already be confirmed as malfunctioning or faulty.

Step 3: Set the ignition switch to “II.” After turning the switch to this position, you have to set the voltmeter to volts. The positive lead (red) must be connected to the VG terminal, while the negative lead (black) must be plugged to the E2G terminal.

Step 4: Blow air into the sensor part of this meter. Be careful not to spit on the wires or the meter itself. As you blow air into the sensor, take a look at the voltage. There should be fluctuations when blowing into the meter. Fluctuations mean that the air flow meter is actually working properly. If there’s no fluctuation on the voltage, then the meter is malfunctioning and has to be replaced.
