This information is beneficial for the engine control unit or ECU for many functions and calculations such as calculating the air density for effective ignition timing and fuel efficiency.
. Bad connection between the IAT sensor 1 and its circuit due to problems like dirt rust and looseness. Common culprits include the following. This is one of the easiest mass air flow sensors to test.
A problem with the mass air flow sensor can trigger the P0113 code. If there is a vacuum leak anywhere between the engine and the mass air flow sensor it causes unmetered air to enter the system. The intake air temperature sensor or IAT sensor has the core function of monitoring the air temperature entering the engine of your vehicle.
The mass airflow MAF sensor is a device that is mounted on the air intake. Its job is to measure the density and therefore the volume. The engine computer PCM calculates how much fuel to inject based on the mass air flow sensor measurements.
Youll test this GM MAF sensor with a multimeter that can read Hertz Hz frequency. In the fuel injection system the mass air flow sensor measures the air flow into the engine. Its job is to measure the density and therefore the volume of filtered air that is drawn into the engine.
The following test is an on-car test that checks the performance of the MAF sensor with the engine running. Intake air temperature sensor 1 experienced an internal problem. The computer system of your engine or.
