Hi.

I have Mazda 323 F 2.0 V6 GT (1997) in my garage. Can someone tell me what is this on the picture in the red circle?

Thanks for the answers.

Mike

it looks like a mass air flow sensor, or an intake air temp sensor, or maybe both. some are combined.

Those would be vacuum control solenoids. Given the location near the MAF sensor one of them should be the fuel pressure regular control solenoid and the other solenoid for the EGR boost sensor.

The EGR boost sensor performs two separate functions. When no vacuum from intake is supplied to it by way of that solenoid it acts as a BARO sensor and sends a barometric pressure signal to the PCM. When the PCM wants to run a self test of the EGR system it switches the solenoid on to provide the Boost sensor with intake vacuum so that PCM can determine if the EGR valve is opening and allowing exhaust gas back into the intake manifold.
