Hi. I have been given a used engine oil level sensor to replace that in my 1HD-T engine (1994 HDJ 80), which is becoming playful. I would like to test it, but have not found a method so far. This is the sensor (part 89491-36080):
It has a connector with two poles, and the black thing on the right is a float that moves up and down. I assumed this would work like a float switch, a circuit being closed (or open) depending on the float. However, I have not been able to find any difference in the electrical continuity between poles whatever the position of the float. There is always continuity.
A new sensor will cost around 400 EUR and, beyond this detail, I would really like to know how it works. Any help would be greatly appreciated.
