I’m stumped. Can’t seem to find any info on this sensor. It’s fitted to the right side of the block, at the back near where the block mates with the transmission. The sensor’s probe points at the flywheel while the wires end in what appears like a test terminal mounted on the engine cover. It is a stand-alone kind of thing; not connected to the car’s wiring harness. Can someone tell me what’s this thing for?
Update 5/3/2011: It’s an Ignition Setting Sender unit, I’ve been told. Hopefully I can find out how it works soon.
