Need to find out what this thread is - it's on an air temperature sensor
for a car.

Its dimensions (male) a- Thread outside diameter Threads per thingie
metric 13.8mm 1.5
imperial 0.54in 16 tpi

Your measurements are probably not quite accurate enough to rely on (i.e. 16
tpi not quite being 1.5mm) but it may be a 14mm x 1.5mm metric fine. It's
apparently not a BSP or NPT thread.
