Should vapor canister purge solenoid be making a ticking noise?

    Bought my truck about a year ago and it has been making a ticking noise since I got it. I can mainly hear it at idle but if I listen I can hear it while driving as well. I did some searching when I first bought it and wrote it off as the 'tacoma tick'. I recently decided to do a little bit more investigating and narrowed it down to a part numbered 25860-75160 using the screwdriver-stethoscope method. Amazon calls it a vapor canister purge solenoid. I don't have any codes or anything so I'm not sure if I should go ahead and replace this part or not.

    No check engine light? After driving and engine off slowly unscrew gas cap. Is there pressure or vacuum HISS ? How fast is it ticking ? Check Amazon again using the my vehicle stats enter VSV or vacuum switching valve. Is this VSV whats ticking?

    Yes they do tick or click but i can only hear it when i test it. It is mounted on a soft rubber pad (noise suppression?) The OEM part is more quiet than cheap aftermarket and OEM includes new soft rubber mount plus last longer. I cant imagine being able to hear it with engine running from inside the cab. The denso part $100+. Aftermarket $9.99 and up.

    Thanks for the comments. Check engine light is not on. I checked the gas cap after a drive and it did make a hissing noise when I opened it. My solenoid had a soft rubber pad on one side but it wasn't mounted to anything, just hanging by the hoses that are connected to it. Maybe it rests against the evap canister or inner fender sometimes and that amplifies the noise. I can hear it ticking over the engine though when I pop the hood while it's running so I think it's louder than it's supposed to be. There is also an unused hole in the firewall nearby as you can see in the background of the attached pic that isn't covered by a grommet or anything which lets more noise into the cab. I'll zip tie it up and see if I can find a grommet to cover that hole and see the noise is still as noticeable.

    I probably won't bother replacing it since the part is $100 and the check engine light isn't on. I mainly just wanted to make sure it wasn't the engine making the ticking noise when I started looking for it.

    I have the exact same problem where it isn’t mounted to anything. Mechanic assured me it was fine. He zip tied it and backed it with some kind of padding(I’ll load a photo later). But, that constant tapping is still present and annoying.
    I have noticed that when I turn off the engine and immediately restart it, the tapping goes away for a few minutes but slowly builds back up to the same volume. Very annoying and was not doing this at the beginning of this year before I had the valve cover baskets replaced.
    Anybody have any ideas on how to more securely fasten it with some kind of sound dampening pad?

    Mine also makes that noise. Mine is kind of loose from the bracket.

    What is the overall opinion on aftermarket vs. OEM when replacing parts such as the purge solenoid? I found one on RockAuto by SMP Intermotor for $73.99. OEM around $122.
    The savings is obvious, but I’m wondering if there’s much difference in quality, longevity, etc.
    Appreciate any input

    Denso is OEM and available online.
    Dorman replacement won't last.
