2015 Jeep Patriot stalled occasionally at red lights

Jeep looses RMP for a split second while driving 80 - 100 KM does this randomly. Also has stalled 2 times while at red lights. Starts right back up, no engine light on, no error codes…

Those are indications that the crankshaft position sensor may be starting to fail.


The tach signal is generated by the crank sensor. And if the sensor fails from engine heat when the stopped, the engine will shut off.
