Re: HELP!!! Ticking noise in engine bay
I once knew what it was - but the point is, it is normal.
While we are talking about it - leaving the key in the "on" position is not a good practice for a whole list of reasons, the least of which is the nearly 45 amps of current the various systems are consuming - your battery will go down very fast if you leave the key ON for very long.
Damn, wish I could remember what it is.... I can't remember if it is the ABS or Traction control solenoid(s), or something or the servo in the throttle body.
