![]() I will be taking an OBDII reading again tomorrow to see if the P0300 and P0660 come back up. It looked awful so it wasn't a bad thing to get that over with. Sorry to bombard you with a bunch of questions but I need to resolve this issue and if I can do it myself (as mentioned, I'm not experienced), it would be ideal. ![]() Doing keyword searches even on a Mazda dealer. Where can I find instructions on how to do these two jobs? This seems to be a void in the forum, too. I cant find the part number for a 2002 Mazda Protege5 2.0 L VICS or the VTCS. ![]() "P0660 is really simple to fix, your VICS solenoid is broken and needs to be replaced. Perhaps there are variations in the abbreviations/acronyms?Ĭan you help me? Did you replace both the VICS and the VTCS? It seems that doing keyword searches even on a Mazda dealer site comes up empty. I couldn't find the part number for a 2002 Mazda Protege5 2.0 L VICS or the VTCS anywhere online. A few minutes after start up the valves open completely and serve no other purpose. I see a part number reference above.but I want to make sure I'm on the right track here with all this VICS and VTCS business! VTCS (Variable Tumble Control System) is a set of butterfly valves in the intake that cause turbulence in the air during cold starts to allow for a leaner fuel mixture, resulting in higher combustion temps and faster warm up. And the next time you do it.it'll be a piece of cake.Hi CheeseHelmet! Thanks for the reply on my long post from Sept. While you're doing it, you might b**** and moan and maybe come up with some new combination of cuss words that never crossed the lips of another human being (but trust me. Once you finish it you'll probably think or say to yourself, "that wasn't so bad". The hardest part of any new thing is starting something you've never done before. PCB had to steer me to it as the new replacement one plugs in a little different vs the OEM one that threw me off. YUP - And if you happen to pop a P0455 CEL, that's the vapor cannister purge valve located on the breather tube going to the throttle body. The wiring connectors and pins are the same. The only differences between the 3 is that the PRC solenoid (also shown in PCB's illustration above and below) is mounted sideways on a separate metal bracket, faces the firewall with the (brown) electrical connector plugged in from the rear, and its reconfigurable filter cap is swapped to the front vacuum port facing forward like the VTCS and the VICS solenoids. On Sale $9.99 each plus free 2-day shipping if you are a Prime member.Īll 3 are the same part - I recommend you replace all three (if you can afford it). It may be a better quality solenoid because it's working with the fuel control system ? I have a 2003 Mazda Protege with the 2.0 L engine. It's the same solenoid, but it has one brass port. Carry out VTCS solenoid valve airflow inspection. My pictures are from the PRC solenoid valve that I replaced. The new solenoid will just push in until it clicks. Then you can even break the old solenoid off. The vacuum tubes and electrical connectors can be removed first. Take a bunch of pictures of what you have before you surf any work. It can be removed and put on the proper port. View attachment 301950 View attachment 301948 There is a lip/clip on the solenoid that snaps into the bracket. The solenoid connects to the bracket like this. The pliers pushes the locking clip down then holds the connector firmly. Grip the connector with a pliers and wobble it around to crack it free, then pull. Pry the tube off with a flathead screwdriver, or grip it lightly and twist it with a pliers to "crack" it loose.ĭon't pull on the wires of the connector. They end up getting stuck and have to be "broken" free.ĭon't pull on the vacuum hose if its stuck, you may break something. may have to remove it to find out for sure because leaks hide in the creases. if not then replace them and if lean code still there then start checking around for other posible air leaks.like cracks in the accordion piece of the air intake. might just be line unplugged or faulty vacuum line to vics. or first check and make sure no problems with vacuum line going to both of those solenoids before spending money. Replace one or both of those solenoids on intake and see if lean code goes away too. vtcs is for cold start and vics is for over 5k rpm rerouting of intake air to shorter route to head. There are 2 of them on the intake, one for vtcs flaps by the head and one for vics flaps in middle of intake manifold. P0660 is intake manifold tuning valve circuit open which also sounds like that white/ green valve is faulty. P2009 is intake runner control circuit low voltage which sounds like the vics solenoid on the intake manifold white and green with vacuum line and electrical plug.
