Trying to find temperature sendor - 2000 Land Rover Discovery

Where the sensor(s) is/are located depends on what engine you have. Please post the make/model/year/engine of your car, and if it's the sensor, "sendor" or "switch" you need.... Some cars have all three. "sensor" is for the computer, "sender" is for your dash readout, and "switch" is for your radiator fan.

the cost varies , by all locations on earth. as does LABOR.
but that is LAST. first is the cause.
it can be, the sendor , wires or guage.
I think on this year, just wires and sender. are top reason.
if you look close the engine can have up to 3 sendors for water temp.
1 for ECU/PCM.
1 for gauge.
1 for A/C engine overheat and drop out.
the answer is here.

contact dealer service on this issue..

The ECT is a two wire sensor, a 5-volt reference signal is sent to the sensor and the signal return is based upon the change in the measured resistance due to temperature. The coorect way to test this sensor is by OHMs, not voltage. See the chart below.

absolutely no idea especially as colour codes can change with the loom supplier in manufacturer ,use a automotive multi meter to test the wires then you will know straight away

most likely your coolant temp sendor is faulty.replace sendor and check if problem is still there

You may have a short in the temp wire itself..........I would do a continuity check on that wire and clean ground......Hope this helps.

If you have the v6 then you will find the coolant temp sendor near the thermostat housing below the throttle body and just toward the front of the vehicle near the coolant bypass pipe. If you have a 4 cylinder then look at the rear of the cylinder head near thermostat.
Good luck.

The coolant temperature sensor on the V6 Passat is located on a pipe
that crosses between cylinder heads on the firewall side of the engine.
A. You will need to remove the plastic cover over the intake manifold.
B. Remove the air filter housing
c. disconnect the Mass Airflow Sensor
D. Loosen the clamp on the far end of the flex pipe going into the intake
Gently pry the flex pipe off the plastic housing and slide it off
the sendor is located around E.

First thing, make sure you have oil pressure - extremely important.

Find oil pressure sensor under the hood - it will be low and possibly around the filter area.
Remove sendor
Insert a mechanical pressure gauge - get at auto store.
Verify you have pressure

Yes - replace the electric light sendor
No - You need to replace the oil pump -

Don't run car without oil pressure - will wear the engine out extremely quick

You can also do a quick check on light circuit.

Disconnect the wire on top of sensor and see if light goes out. Usually these are a grounding device in sensor.

Yes - The indication or no oil pressure or sendor bad - see above.

No - you just have an electrical problem - short in the cable from light to sendor, but I would also check the pressure mechanically to make sure.
