  • I have verified that the IAC fill / cap pressure is causing a constant leak in the purifier. He had never done this before. Tried 3 Honda Iac 2 and After Market Iac. They all do the same thing. Strong constant vacuum leak from this sealed cover. Does anyone have any inspirational ideas? I took everything from TB After Market Place and invested in TB Capital, but he always did the same thing. The ringtone was reset to original, but the issue persists.

    Hello GB! I needBut it’s interesting to know about the IAC and the scheme, if the PCM can order the IAC to unblock (or even be able to) the block, since all your symptoms point to a closed IAC. Poorly LOCKED closed because you have tried other valves. At least not an open creature.

    The net leak you find can only be due to the fact that the IAC is completely closed when the engine is running, and the air intake is strongly sucking the IAC vent plug. Most Ford models with this type of valve do not pick up this vacuum leak sound, mainly because the IAC is partially open, which is a problem for idle.

    I can actually suggest some quick tests. One is to take IAC out of target use so that it stays connected. Keep a close eye on the IAC pin, even if someone else starts the engine. Of course there will be a lot of oil leakage, but you should see some movement of the pin. If you don’t see any response, it most likely indicates a control problem.

    Another theme you can do is use better control A separate IAC lamp next to the running engine. When the B- light is connected, the pink wire should glow brightly. If the light test is currently connected to B +, then the entire white / blue wire should have partial brightness or pulse descriptor. If you do not see a heartbeat, it indicates that there is no PCM effect.

    How does the IAC control idle speed?

    The idle air exposure valve literally directs air around a completely new closed throttle valve so that the car can suck in air at idle speed. Since it is a bypass air valve, it is also considered an air bypass valve. In the days of carburetors, idle speed was adjusted with a large idle screw. First, the throttle valve does not have a reliable venturi.

    I made a test test.light. The indicator came on when I connected the test lamp to the red cable and the white / blue cable must have lit up too. When I strangled the TB car, a blue-white transmission flashed.

    What I also did was pull out the plug, then pulled out the Iac and looked at the location of each needle, then plugged it back in, drove the car to pull it out, and put it back in the sector. While the car was on, including the air conditioner, Iturned off IAC (automatic idle mode remained the same) and then turned off the machine. I took off the IAC and found that all the IAC pins were in the same place when the car was cold. It looks like he didn’t budge.
