I've had an intermittent tach issue for a few years now. I will be cruising around and then the tach will go to zero rpms--sometimes just briefly, sometimes long enough to throw a check engine light. The issue seems to occur more recently the hotter, or longer I've been driving the car. I finally decided to change my cam sensor with a brand new Motorcraft sensor. Unfortunately, this did not fix the issue and about 20 minutes into my test drive, the tach went to zero and through a check engine light. I have not tried pulling codes. The light goes away as soon as the tach starts working again.
Ideas?
