Purge control solenoid valve noise

Post by subzerocarfanatic »

I notice on occasion, probably more frequent that not because at times it is not easy to hear, there is a tapping sound, I have looked and looked everywhere trying to find the noise. I put my hand on the purge control valve i believe it is, it has 2 lines going in both ends of it and it mounts by two poles ends that push into the driver side upper area of the radiator housing area, i believe it is the SMOG purge control valve, what could be making the tapping noise, i place my hand on the valve and can feel the noise i'm hearing, sometimes it does not do it .

I was testing mine recently with a 9 volt battery and it clicks when it opens, but I'd be very suprised if you would hear that when the engine is running.

That's how it works,it is pulsing...usually at idle(or when ecu ask for it) will make clicking sound,indicating that it is working.
Nothing wrong with it...it works properly.
