you can get a clicking noise from the VVT actuator if you have low oil pressure or if the unit is clogeed up ?
So I'd suggest as the next step to do an oil flush treatment and then replace the oil and filter with fresh items to see if this helps
and yes I'd also agree that its worth checking over the grounds
there are some small ground connections that run out of the engine bay wiring loom and are secured to the engine with small ring terminals
these are the ECU specific earths so these should be bright and clean
sometimes sensor 3 can mean sensor 2 or the last sensor on the exhaust after the engine
so its worth checking over the wiring and connector for that part
and for the clicking noise to come from the VVT with the ignition on but engine off( which is what I presume you meant) is very likely that the solenoid ( 2 wire valve on the cam cover) is faulty or has a short to ground
so I'd again check the state of the wiring and connector to this part and replace it if that looks OK
do you still need help?
