How to Install an Air Intake Temperature Sensor
The air intake temperature sensor, or AIT sensor, measures the temperature of air moving into the vehicle engine via the air intake pipe. The temperature sensing unit on your car is found in the air intake pipe that extends from the filtration system to the gasoline injection device. In case your car is moving roughly, has difficulties starting up and regularly stops in the course of ordinary cruising, it's quite possible that the AIT indicator is faltering and should be changed. Correct operation of your vehicle's air intake temperature indicator will assist you to prevent expensive restorations to your car engine and various parts. Air-intake receptors are easy to check at your home to make sure they are functioning properly.
Step 1 – Study the Purpose of AIT Sensor
First, you will want to understand the function of the air-intake temperature indicator. The sensing unit keeps an eye on the temperature of the air moving in the vehicle exhaust system. The AIT sensor is found in the air purifier casing or opening and enables the vehicle's computer system to control the car exhaust fuel circulation.
Step 2 – Know the Meaning of a Lamp Light
Then you'll need to recognize the right time to check the sensing unit. The Test Engine or perhaps Service Engine lamp flash along with your first signal shows that a problem exists. When this happens, it may be a real issue or perhaps a faulty sensor.
Step 3 – Check the Air Box
Open the car bonnet and find the air container. It must be on the other end of the engine bay close to the front side of the car. It will probably be a plastic, box-like item that has a big plastic tube out to the rear of the car engine.
Step 4 – Examine the AIT sensor
Check the new Air Intake Temperature sensor. You will be searching for this device in the air container.
Step 5 – Remove the Filter
Take out the air container top and take the air filtration system out.
Step 6 – Remove the Clamps
Release the band clips on the air-intake pipe using a screwdriver and yank the air-intake pipe from the air container.
Step 7 – Disconnect Power
Remove the electric power link to the Air-Intake Temperature indicator and remove the Air-Intake Temperature indicator from the air conduit system. Take out the Air-Intake intake temperature indicator soon after first detaching the air intake casing. Allow the engine to cool down prior to removing the AIT, because you may be seriously burned. Make it possible for the sensing unit to cool down prior to more testing. You should get a voltmeter and air drier to carry out the testing portion of this process
Step 8 – Reassemble the AIT unit
Mount the new Air-Intake temperature Sensor and place the air container parts back together. Setting up the AIT unit is the opposite of taking out the AIT.
Analyze the AIT's resistance while it is cool by lifting the sensor on the voltmeter. Observe the measurement that is registered. After that make it warm using the hair drier and analyze it once more. Look at your car's service or maintenance handbook for the appropriate voltmeter range. Install the sensing unit again if it is inside the range. In case you are still getting the same complication, reset your vehicle's computer system by removing the negative battery negative charge for 5 minutes.
