No voltage at some sensors
#4
Sounds like the brown sensor is fine but you'll somehow need to fix the wiring to the plug. Not easy if it's very close to the plug & as far as I'm aware those specific plugs aren't aware as a replacement. There are work-arounds.

As far as I know all the petrol models had another 2 coolant temp sensors - a green one which sends info to the ECU (adjusts fuel mix according to engine temp), and the blue one, which feeds the temp gauge in the instrument cluster.

Assuming you were asking, the other sensors your engine will have are:

> Crank position sensor - can wouldn't start without this functioning so must be providing sufficient signal
> MAP - senses the air pressure in the manifold to help calculate how much air the engine is drawing in
> Knock sensor - detects 'pinking' due to pre-ignition
> Air intake temp sensor
> Throttle position sensor
> O2 (lambda) sensor - in exhaust

The ones the engine really relies on are the green coolant temp sensor, throttle position, MAP & O2 sensors. If any of these were significantly out it would run fairly badly, but likely it would run.
