HOW I CAN CHECK OIL LEVEL SENSOR
There s/b a finite resistance between pins 1 and 2. Even if this is so, the sensor can still be defective. I suggest that, if the dipstick shows full, and you're getting a Low Oil message, merely replace the sensor. It's a known, but rare, failure. You'll need to drain the oil, and replace the O-ring.
Continuity is used to check that a circuit is continuous, and not broken. It does not measure resistance. Example: an electrical fuse to see if it is truly blown.
Resistance is a measure of the impeding of current flow. In the case of the level sensor, the resistance element heats the sensor.
Diode test is to determine if a diode is defective; one polarity actually measures the junction voltage, and the other polarity shows nothing, which indicates that the diode is working.

My thermostat for 206 Peugeot not working and flicks "stop"
before you spend money ( and you have doubts) get a second opinion and run the fault codes . There is a problem in that the thermostat has nothing to do with the ECM ( computer box) all it does is control the water temperature in the cooling system by opening and closing according to the coolant temperature
water temperature sensors send signals to the ECM so that the ECM can adjust the air/fuel mixture according to the engine temperature . Talk around as it may save you heaps of cash.
Peugeot 206 1.4 8v engine everything works on towing but engine will not fire up
This won't be a whole lot of help to you but modern CanBus cars are very fussy about their electrics and unless you're an expert at fitting towbar electrics yourself you'll need to find a company that is. If you already have the harness, socket and bar, then an auto-electrician should charge you a lot less than £100 to sort it for you.
