How To Trick A Mass Air Flow Sensor – A Brilliant Guide

A mass air flow (MAF) sensor is used to determine the mass flow rate of air entering a vehicle’s engine. The MAF sensor measures the amount of air flowing into the engine through the air filter. This information is used by the engine control unit (ECU) to calculate the appropriate fuel delivery for the engine.

The hot film of the MAF sensor is constantly heated by an electric current offered by the ECU. This hot film is used to measure the airflow into the engine. The amount of current required to maintain the hot film at a constant temperature is directly proportional to the mass flow rate of air entering the engine. Thus, airflow decreases the resistance of this component, which decreases its heating power.

If the sensor is not working properly, your check engine light will be on, your car will behave erratically, and the engine will not run efficiently. A mass air flow sensor is an important part of a car’s engine and can be expensive to replace. If you’re looking to save money, you can try tricking the sensor. Here is a way to trick a mass air flow sensor so that it will work properly.

How To Trick A Mass Air Flow Sensor

A faulty Mass Airflow sensor will activate the light on your dashboard. In general, bypassing is undesirable since it costs money unreasonably and, if left unchecked, could result in serious issues. Below are the steps to trick the mass air flow sensor.

  • Step 1: A specific tube with the same size and shape as your MAF sensor is made to the same specifications. The tube made of metal performs a similar purpose as the mass air flow sensor, which is composed of plastic.
  • Step 2: To heat up and give your Mass Airflow sensor a temperature that is comparable to the fuel-air mixture coming out of the vehicle’s tailpipe, place the tube in front of the ignition source.
  • Step 3: Be aware of the heat released from an open flame as this could cause the mass air flow sensor to read higher than necessary. Your car’s engine will be at risk from this phenomenon.

Remember that tricking only serves as a temporary fix for a damaged Mass Airflow sensor. When the problem is more severe, think about using a new sensor. Before sending the car to a mechanic, drivers must know how to trick a mass air flow sensor in order to have a quick repair in addition to resetting the Mass Airflow sensor. When this component fails, the reading and the stated miles per gallon will be invalid. As a result, you have to spend more money on fuel purchases and car performance upgrades.
