Clicking sound under the hood

There a sound that started at about 2k miles. And it's just a clicking that I can hear especially when stopped. Does anyone know what this is or has the same thing?

 

Otto Atkinson cycle

 

What exactly is that?

I did just read it I'm just confused because when I ride in my buddy's 2016 sport you can't hear the clicking like mine. Is there anything to be worried about

 

it's under warranty take to dealer

 

It should be the fuel injectors self cleaning during a hot run or idle. I notice it when i been driving for a while, at the stop light it clicks. Try googling 2016 tacoma self cleaning fuel injectors

 

Direct injection engines are louder then port injection engines due to the high pressure needed for the direct fuel injectors.

 

Thanks for your help everyone. It's definitely the self cleaning injectors. Now I just wish I could turn it off. It's very annoying when sitting in traffic.

 

Check the adhesive under your hood. Maybe it's separating under the spars. This could cause some flapping noises

 

Ya. But if you have your radio on, you wont be hearing anything. Has anyone know how to turn off the door buzzer?

 

I haven't heard anything but that's something I'd love to know also

 

Always on a roll.
