Here is a used OEM crankshaft position sensor for a 1999-2005 Mazda Miata MX5. Way way way better buying a known good used OEM sensor as opposed to buying a new aftermarket one. Have had every aftermarket sensor fail and have used OEM sensors every time and they worked without fail. These are all known good sensors and were pulled from a running and driving car. Buy these with confidence instead of having to spend more and take a chance with an aftermarket or parts store sensor. Fast and free shipping!!
