strange ticking sound after I turn car off
 

when I am either idling or turn the car off after driving I hear this faint ticking sound that is coming from under the car. My friend said it was possibly a heat shield and I don't really need to worry about it is that true?

Heat shield, an when you turn the car off that clicking is the throttle bodies checking something or something, lol

Probably some electrical part "resetting" (DEpointfive0's TB sounds like a likely suspect).

"Ticking" doesn't tell us much. How fast do the ticks occur? Periodic/random/variable? How long does the ticking last?

There was a thread on it before, forgot what the hell was being checked

It's like a few ticks a second . It occurs for a minute or two after I turn the car off but it might still make the sound when the car is on but I can't hear it over the engine

prob you catalytic converter cooling down. Typically it will make a ticking sound for a little while after you shut your car off until it has fully cooled down.

Happens on most, if not all of my cars...nothing to be alarmed about

(my emphasis) I think italy3541 is right about the cause being the car cooling down - the electrical noises only last a few seconds. My guess would be the engine itself but it could be the exhaust.

As per Amj2020, it's nothing to worry about (assuming the noise is caused by cooling). I don't remember having a vehicle that didn't do it.

Back when I was in high school, I would drive my Mom's Electra 225 with 455 CID engine like it was stolen and it would tick and pop for 10 minutes or so after shutdown. :)

Check to make sure George Costanza didn't make a place to take a nap under your Z ;)

Yea I remember that thread too. It was concluded as the clicking sound was the pop corn.:p

OP, most of my cars making that noise too. It's just the car being cooling down. Nothing to worry about.

Happens to my 2009. No worries.
