Irregular ticking noise from engine - 2023 TRD Sport

It’s totally normal
Like someone said it’s the Cleaning cycle , don’t put one bit of worry into it . People always seem to get freaked out by it . You need to worry more when you hear a thumping sound from the bottom of the motor lol

 

i have same noise. i just bought mechnic's stethoscope and it appears to be very good.
i will go check my hpfp and vac pump. they are in same area from which noise emanates.
my guess is vac pump from what people have been posting. and is normal.
will post result of stethoscope probe at some point.

finally got around to it.
first: this stethoscope is fantastic. in the past i have used the screwdriver to the ear trick, but this thing is amazing. it really isolates a noise from the rest of the racket under the hood.
i checked the hpfp first and it had some noise, to be expected since it is mechanical, and sounded just fine.
then i checked the vacuum pump. it is louder and i believe the source of the loudest racket.
if you want to pin point where a noise is coming from, i highly recommend this tool. i did not expect it to be so useful (and cheap).

edit: just checked link since i paid $7 and pic in post says $16. keepa says it jumped to $16 a few days ago but it is back down to $7 again. don't pay $16.

 

were you able to figure it out? I got the same noise and it’s driving me up a wall too.
