Testing air and oil temperature sensors

I recently had occasion to test the sensors because I had a 1999 R1100R that was hard starting. After the engine started, it ran fine. I also tested the air temperature sensor on a 2000 R1150GS. I only tested the oil temperature sensor at room temperature (83).

I started using a non-contact infrared thermometer and a heat gun. The non-contact thermometer was too variable and the sensor cooled too fast, so I switched to water and a dial faced stick thermometer.

I found the oil temperature sensor was open circuit. After replacing it [$20 ebay inc shipping!] the engine started easily.

Did you have any faults on the Motronics for the oil temp sensor?

Here's a good explanation of the oil sensor fuel gauge and RID. Oil, Fuel, RID

And here is the data on the air temp sensor: http://bmwsporttouring.com/ubbthreads/ubbthreads.php?ubb=showflat&Number=769393#Post769393

I didn't think to access the outputs from the Motronic. That's done by grounding something then counting blinks of something else, right?

or use GS-911 device?
