What is the MAF sensor on a Subaru Impreza?
Basically, the MAF sensor—also known as airflow meter—measures the . Check your repair manual, ask at your local auto parts store. Varies you need factory wiring diagram to verify 02 sensor output signal Indicates that you will be connecting to the (MAF) Mass air flow sensor, all others L Non Turbo.
Are there any issues with the Subaru air flow sensor?
Subaru mass air flow sensors often have issues with performance. When car owners face these issues they often have questions that need answered. Read below where Experts have answered a variety of questions about Subaru mass air flow sensors.
Where can I find the trouble code on my air flow sensor?
When the air flow sensor signal varies from the expected range, the PCM records a fault and stores the corresponding trouble code, illuminating the Check Engine light on the dash. This trouble code can be retrieved with a scan tool. The following trouble codes are usually associated with a mass air flow sensor:
Subaru mass air flow sensors often have issues with performance. When car owners face these issues they often have questions that need answered. Read below where Experts have answered a variety of questions about Subaru mass air flow sensors.
How to test pressure switch on Subaru Impreza?
There are several factors involved in getting power to the compressor. The first thing to check are fuses. If OK, you have to trace all wires to key components to determine where is the failure. That’s the way we do it. Feel free to email me for a system diagram, specifying your Impreza’s engine size and if it has automatic or manual A/C.
Why is my mass air flow sensor not working?
On starting a Subaru Impreza where the mass air flow sensor was changed the oil temperature light flashes and the engine sends a maf code what could the cause be? If after replacing the mass air flow sensor the code still remains, chances are that the issue is with the wiring to the sensor rather than with the sensor itself.
How many wires does a Subaru pressure switch have?
So here is what I think I’ve figure out so far. With gauges connected, system has 80psi on hi and low side. When AC compressor is jumped and running low side is about 20psi and high side is 110psi. Per the wiring diagram, the pressure switch has 4 wires. Terminal 1 is power from fuse 22.
