How much does it cost to diagnose the b1479 Toyota code?
The cost of diagnosing the B1479 TOYOTA code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour. The Flow Sensor is built into the compressor and outputs a signal indicating the flow rate of the refrigerant.
Why does my Camry no a / C have code b1479?
If you OHM test of the wires and a checked good and you have a constant 3.76 V and it does not change while trying to use the air-conditioning and you disconnected the connector and the reading on the scan tool went to 5 V the problem is not in the wiring.
What does b1479 flow control circuit code mean?
A B1479 Flow Control Circuit code indicates either a short or open in the flow control sensor circuit. To eliminate the possibility of an open to the sensor, disconnect the electrical connector and check for 5 volts.
Where is the DTC b1479 code on a RAV4?
I found out that my 2009 4WD RAV4 (manual a/c) has DTC B1479 code stored in the a/c unit and it blows hot air. For the RAV4 manual a/c I found a similar diagram but cannot find location of the AC amplifier connector E37.
Why is the AC clutch on my Toyota not working?
If the AC compressor clutch won’t engage on your late model Toyota and you find a B1479 Flow Control Circuit trouble code stored, the problem is usually a bad flow control sensor. Toyota uses the AC flow control sensor to detect the amount of refrigerant flow through the compressor.
What should the return voltage be on a Toyota Corolla?
If you detect 5V from the AC amplifier, turn on the AC and check for return voltage. It must be above 0.3V and less than 4.7V and should vary. If it reads below 0.3V or higher than 4.7V (gor more than 5-secs), replace the sensor. Unfortunately, Toyota doesn’t seem to sell just the sensor and recommends replacing the entire compressor.
