Fuel Pressure Regulator Control(PRC) Solenoid Valve, Exhaust Gas Recirculation(EGR) Switch for Mazda RX-8/626/MPV/Protege by LIAMTU

I bought two of these for my Protege5, which was throwing codes. One to fix the Fuel Pressure Regulator Control Solenoid (aka PRC), and one for the Intake Manifold Runner Control Solenoid (aka VICS). Took 5 minutes to install and solved both codes. Just FYI, these solenoids are used in a lot of different places on the FS-DE engine, and I'm sure they have applications on other Mazda engines from the mid-90s up until the mid 00's. In the Protege5, this same solenoid is used for EGR, VTCS, VICS, and PRC among others. Might as well buy a few to have them around if you're planning to keep the car long term and it has high miles.

worked for 2003 mazda. It works for a lot of the solenoids on my mazda recently found out you could switch the little black filter by pulling it off so other ports can be used. That is the only difference for my emission control solenoid and fuel pressure control solenoid. So if it looks like the one you have but the little black part is in a different place it will work if you move the filter to the port that matches the old one. then plug your lines in the other ports.

Picture just looked wrong. I had a run issue on my Probe GT, after warmed up, especially on these 100 degree days. It raises fuel pressure, preventing Vapor lock. Signs of this can be from surge at steady throttle on freeway, to a dead miss. The end cap can be moved, as I said in video its how convert it from the VRIS to PRC. If your VRIS on the 2.5L is not working, you'r missing out. Really wakes the engine up. PRC is 5 star for ease to install, the VRIS is 3 star, it requires a 10mm wrench.... Seen posts on so called mechanic sites asking about run issues, and none of the so called experts suggested it.

Works great in my '96 Miata

I bought this to try and fix a P0200 code my Mazda Protege5 (2003) was showing. The car would start rough when warmed up sometimes. No check engine light, but the code was persistent. It *seems* to run better, I cleared the code and have only had this item on for a couple days, so we'll see if the code comes back on or not in time. I did have to move the oblong piece that was bottom/rear to the front of the piece. Install is pretty dang easy on these.

I can't find this part on my car. I believe its called more than one thing or something. It looked cheap as hell any who. It came with no part numbers or anything on it. Just the box. I gave three stars because it came fast . And I didn't pay much so what do I expect .

Came as expected. Fixed my lack of vacuum at the fuel line issue

I bought this regulator for my 95 Mazda Miata 1.8 To fix the cel. It’s by far the best bang for the buck and all you have to do is switch the cap to the correct port. Would recommend this to anyone with a 1.8 miata throwing a 25 code

Should have instructions explaining that the vent cap can have the position changed to be used as the egr sensor
