Car Computers and Sensors
Where is the crankshaft position sensor located on the 1991 Mazda miata?
Should be in the same place as all of the '90-'93 1.6L engines.
On the back of (bolted to) the head/valve cover (closest to the
firewall). You should see the plastic wiring harness connector
sticking up/left (toward the passenger side) from it.
