What does an aftermarket MAF sensor do?
Upgrading to a performance mass air flow sensor will allow your vehicle to support more air. This is because it has a larger bore hole. It can also allow for a more accurate reading, making sure your vehicle’s computer is always getting an accurate reading.
What does a MAF sensor measure?
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. This causes the engine computer to miscalculate the amount of injected fuel, causing additional damage to your engine.
Is the IAT built into the MAF sensor?
On some module with a mass air flow (MAF) sensor, the IAT is incorporated into the same housing On some models with a manifold absolute pressure (MAP) sensor, the IAT is built into the sensor as well. If necessary, consult your vehicle repair manual to locate the sensor. III. Different Names for the IAT Sensor
How are mass air flow ( MAF ) sensors used?
Mass Air Flow (MAF) Sensors Mass Air Flow (MAF) Sensors The Mass Air Flow Sensors converts the amount of air drawn into the engine into a voltage signal. The ECM needs to know intake air volume to calculate engine load. This is necessary to determine how much fuel to inject, when to ignite the cylinder, and when to shift the transmission.
What are the trouble codes for the IAT sensor?
On most OBD1 applications, two trouble codes are associated with the IAT sensor. A code 23 indicates the intake air temp reading is lower than expected. If this code is present, before replacing the sensor you should check for an open circuit to the IAT sensor wiring. A code 25 indicates the intake air temp reading is higher than expected.
Which is the most common air flow sensor?
The vane air flow meter and Karmen vortex are two older styles of air flow sensors and they can be identified by their shape. The newer, and more common is the Mass Air Flow (MAF) sensor. Mass Air Flow Sensor: Hot Wire Type The primary components of the MAF sensor are a thermistor, a platinum hot wire, and an electronic control circuit.
