Remove the intercooler first. The knock sensor is located under its loation. But you will have to remove some breather pipes to get to it. You will need a long ratchet.
Yea mate no problem
The knock sensor on a Vauxhall Vectra X Reg 2.0 SRI is typically located on the engine block, specifically on the lower part of the engine near the cylinder head. It is usually mounted on the side of the engine, often near the exhaust manifold. To access it, you may need to remove some components for better visibility and reach. Always consult the vehicle's service manual for precise location details and any specific procedures.
I don't happen to know what a "51 reg 2 2 dti" is, however the throttle position sensor is found on the end of the throttle shaft.
The water temperature sensor is located on the front of the engine. You will find the sensor behind the thermostat housing.
just after your Airfilter
no the 85 it is on the fuel pressure reg it should be the same
Could be temperature sensor Could be gauge
that would be either fan switch or temperature sensor

Reg Reg Askew is 5' 11".
It doesn't have a hall chip or a hall effect sensor, it has an inductive pulse cam/crank sensor. You can clean those.
the usual fault is a dirty or open circuit crankshaft sensor
