Let the air into the intake......
can u tell me what wires do what on the air intake sensor on a 2007 vectra 1.8 sri
The Intake Air Temperature sensor is either part of the Air flow sensor, or a separate sensor in the intake pipes not far from it.
The idle air control valve on a Vauxhall Vectra B is located on the intake manifold. The valve is placed in front of the air tubing, right behind the engine cylinder head.
take the air intake pipe off the top of throttle housing clean inside of chamber with choke and carb cleaner put the air intake pipe back on and start car light shuold go out.
if it has air condition it is behind the pollen filter under the bonet
Just after the airbox before the air flow sensor
Because most if not all vauxhall engines are air cooled, hence when you are driving the temp comes down
my was falt in drivers seat belt but there are heaps of other things that can bring this problem up
Cold air intake, supercharger and down pipes.
Youll need to remove the air box if its on a vectra B. Then remove the cambelt cover. There should be a bolt between the cam pullies, undo it and left out sensor.Then put everything back in reverse
Open the bonnet and to the left your see the air filter box follow intake pipes till you see a cable that runs to the intake manifold its there Sounds to me the cambelt tensioner has weakened causing a rattle sound around 2000-3000 rpm
I am not certain if there is another sensor,but the inlet air temp is monitored by the MAF unit.(mass airflow sensor between the air filter and the inlet pipe).
