Does anybody know what is on the crank the the sensor reads. Magnet or magnetic paint mark? And can this be seen with the cps out?

The trigger is teeth. They are non-magnetic. The sensor is the magnet.

Ty for your info Grcauto..found the info on the net. But do have this issue resolved. Wiggling the wires was no help. But unplugging the sensor and tightening the female connection did the trick!!!!, back probed the connector with a voltmeter the issue went away

Actually, the sensor is Hall effect sensor. When you put voltage across the wire it creates a magnetic filed. When a metal containing iron passes through the magnetic field it disrupts the field. Sensors like the CPS have 3 wires. Two wires are used to create the magnetic field and the 3rd wire is the sensing wire.

Actually, it's not.

A Hall Effect sensor would have 3 wires. The crank sensor is a variable reluctance sensor, and it only has 2.

Oh, welcome to the forum, by the way.

If I helped you fix it, why not...

Your support is greatly appreciated
