I have a 05 tc with a K&N CAI. I have recently been hearing a ticking sound kind of like change getting tossed ina dryer. It is coming from the upper intake pipe around the MAF sensor area. What could it be? when i rev it goes away and then when it returns to idle after it warms up it ticks again. I live in NJ and it is betwen 20-30 everyday.
Thanks

 

You didn't drop anything into the engine? Nut, bolt or socket? Could be your intake is rubbing against the car and vibrating.. check to see if you have any metal on metal touching. All I can think of.. doesn't sound like the issue I was having.. if you read that at all.

 

There is no metal on metal rubbing and the intake was never removed and it just started ticking recently.

 

And your positive you think its from the intake itself or the general area? How many miles do you have?

 

9000 miles but i will check again

 

Thats normal, if it from the intake area. I forget the name of the part but it has to do w/ the vacum system. If it was coming from the the part of the motor where the pulley is then you have a problem like gotti.

 

I am almost willing to bet its metal on metal.. somewhere.. if your reving and it goes away.. and if its sitting there its making a "change in dryer" ticking.. sounds like you have something tapping on each other.

 

I dont think its the same issue that I had.

 

When i hold the sensor the blue one i can feel the ticking through that. also when i put my ear near the upper intake pipe near the sensor i can hear it. Should i bring it to the dealer.

 

Does it have anything to do with the cold weather? It started when i starting getting extremly cold. Also it will only tick when the engine is fully warmed up.

 

Is there a relay or something in that thing.. anyone know? I guess you should put your stock airbox on, then go.

I couldn't tell you for sure.. I would just take off your intake and goto the dealership and have them look at it. Unless of course someone else could chime in and tell you what they think it is.

 

when u installed sis u reset the ECU? mine did the same until i did

 

Ive got this noise too. it comes from around/behind the intake. sometimes its loud, sometimes it isnt there.

 

I reset the ecu buy disconnecting the battery but what is SIS? was that a typo.

 

the ticking sound is from your VSV... (Vacuum Switching Valve) and it is normal.. it's just doing it's job.

 

why would it start all of asudden? It started when it got extremly cold and in the summer it didnt make the noise at all.

 

You probably never noticed it until you started working and installing things...

 

Yeah, I have the same rattle. It come from the driver's side, around the wheel well. And my boy who has a 06 tC has heard it also. Mine has been off and own since mid summer. PLEASE PLEASE ANYONE IF YOU FIGURE OUT WHAT IT TRULY IS LET ME KNOW!!!!!!!!!
