B1479 Flow Sensor Circuit

The B1479 flow sensor circuit is a control unit that monitors and regulates the engine’s air intake system. It is responsible for managing the airflow through the engine and maintaining the correct air/fuel mixture. The B1479 flow sensor circuit is located in the engine bay, on the left side of the vehicle.

It consists of a housing, an air filter, and a throttle body. The housing contains several sensors that monitor the airflow and pressure within the engine. The air filter helps to keep debris and other contaminants out of the engine.

The throttle body controls the amount of air that enters the engine.

The B1479 flow sensor circuit is used to measure the flow of fluid in a closed system. The sensor consists of a piezoelectric crystal that generates an electric current when it is deformed by the flow of fluid. The current is proportional to the rate of flow and can be measured with a digital multimeter.

The B1479 flow sensor is ideal for measuring the flow of water in a plumbing system or the flow of oil in an engine. It can also be used to monitor the level of fluids in storage tanks. The sensor is easy to install and does not require any special wiring or plumbing.

Toyota Ac Flow Sensor Bypass

If your Toyota’s check engine light is on, and you’ve been told that the problem is the mass airflow sensor (MAF), there’s a simple way to test this before spending money on a new MAF. This bypass trick will also work on other cars with electronic MAF sensors. First, disconnect the negative battery terminal to prevent shocks.

Then, locate the MAF sensor behind the air filter box. On most Toyotas, there are two screws holding the air filter box in place. Remove these screws and lift off the lid of the box.

The MAF sensor will be right there, mounted to the side of the air intake ducting with two wires running to it. Carefully unplug the connector from the MAF sensor (don’t touch anything else). Now take a length of electrical tape and tape over one of the exposed wires on the connector (it doesn’t matter which one).

Re-attach the connector to the MAF sensor and re-install everything in reverse order. Start up your car and see if the check engine light is still on. If it is, then you’ll need to replace your MAF sensor.

If not, then congratulations – you just saved yourself some money!

Toyota Ac Flow Sensor Replacement

If your Toyota’sCheck Engine Light is on, there’s a good chance that the Mass Air Flow (MAF) Sensor is the culprit. The MAF sensor measures the amount of air flowing into the engine so that the ECU can calculate the appropriate amount of fuel to inject. Over time, the MAF sensor can become coated with dirt and debris, which can cause it to fail.

Fortunately, replacing a MAF sensor on a Toyota is relatively easy and only requires a few tools. This guide will walk you through the process step-by-step so that you can get your car back on the road as quickly as possible. Before you begin, make sure that you have disconnectiong negative battery terminal cable to prevent any electrical shorts.

Once you’ve done that, locatetheMaf Sensor o nthe front ofthe engine near wherethe air filter housing attaches. There are usually two screws holding it in place – remove those and carefully unplug the electrical connector from teh senor itself. Now it’s time to installthe new sensor.

Simply reverse the steps above – screw in teh new sensor and reattach teh electrical connector before reconnecting teh negative battery terminal cable . Start up your car and check for any codes – if all goes well, your Check Engine Light should be gone!

How to Bypass Ac Flow Sensor

If your car has an AC flow sensor, you may be wondering how to bypass it. Here are a few things you need to know about AC flow sensors and how to bypass them. What is an AC Flow Sensor?

An AC flow sensor is a device that measures the amount of air flowing through your car’s air conditioning system. It’s usually located near the air filter or in the ductwork leading to the evaporator. The sensor contains a hot wire that cools as air passes over it.

The cooling of the wire produces an electrical signal that’s proportional to the airflow. This signal is then used by the car’s computer to adjust the amount of refrigerant being pumped into the evaporator so that it can maintain a consistent temperature. Why Would You Want to Bypass It?

There are a few reasons why you might want to bypass your AC flow sensor. If your sensor is damaged, it can cause your air conditioner to cycle on and off frequently or blow warm air. Bypassing the sensor will allow you to continue using your A/C without having to replace the sensor.

Additionally, if you live in a area with high humidity, bypassing the AC flow sensor can help prevent mold and mildew growth inside your A/C unit since there won’t be any moisture for them to thrive on. Finally, if you have an older car with an analog compressor clutch, bypassing the AC flow sensor can help prolong its life since there will be less wear and tear on the clutch from cycling on and off constantly.

What Does an Ac Flow Sensor Do?

The air conditioning (AC) flow sensor is located in the AC system and is used to measure the amount of coolant flowing through the system. The AC flow sensor is a vital part of the AC system and helps to keep the AC system operating efficiently. The AC flow sensor is used to monitor the coolant level in the AC system and to keep the AC compressor from overworking.

How Do You Change a Ac Flow Sensor?

How to Change a AC Flow Sensor The air conditioning (AC) flow sensor measures the volume of air that is passing through the AC system. This information is used by the engine control module (ECM) to determine the amount of fuel to inject into the engine.

If the AC flow sensor is not working properly, it can cause the engine to run lean or rich. A faulty AC flow sensor can also cause the check engine light to come on. In most cases, you will need to replace the AC flow sensor if it is not working properly.

To change the AC flow sensor, you will need: -A new AC flow sensor -An OBD-II scanner

Instructions 1. Locate the AC flow sensor. The exact location of the sensor will vary depending on your vehicle make and model.

Consult your owner’s manual or a repair manual for your specific vehicle for more information. The AC flow sensor is usually located near the air filter box or in front of the radiator. 2 Use an OBD-II scanner to clear any codes that may be stored in memory from a previous malfunction with the AC system or other components.

Make sure that there are no pending codes before proceeding with replacing theflow senor otherwise they may reappear after installation.. If you do not have access to an OBD-II scanner, you can usually clear codes by disconnecting and reconnectingthe battery terminals.

. However, this method may not work for all vehicles so consult your owner’s manual first.. 3 Unplugthe electrical connectorfromthe back ofthe oldAC flowsensorand removeit from its mounting bracket.. 4 Install thenewAC flowsensorinitsmountingbracketand plug inthe electricalconnector whenyou’refinished.. 5 Startyourengineand let it idlefora few minutes sothe ECMcan relearnitsfuel mapsettingswiththenewflowsensorinstalled.. 6 CheckforcodesagainwithanOBD IIscanner top make surethat everythingisworkingproperlybeforeclosingupyourenginecompartment ..

What is the Sensor on the Ac Compressor?

The sensor on the AC compressor is a pressure switch that turns the compressor on and off based on the pressure of the refrigerant. If the pressure is too low, the switch will turn the compressor off to prevent damage.


The B1479 Flow Sensor Circuit is a simple, low-cost way to measure flow rates. It can be used to monitor the flow of liquids or gases, and can be interfaced with a variety of electronic devices. The sensor consists of two parts: a transmitter and a receiver.

The transmitter emits a signal that is received by the receiver when the liquid or gas flows past it. The strength of the signal is proportional to the flow rate.
