We all know a crankshaft position sensor (CKP) is an electronic device used in a Dodge Stratus internal combustion engine to monitor the position of the crankshaft. But do you know where the crank sensor is located?
The particular position of the crankshaft sensor is different for 4-cylinder and 6-cylinder models. The 4-cylinder crankshaft position sensor is located on the front of the engine below the starter.
The crankshaft sensor on 2.7-liter 6-cylinder model is located on the rear of the transmission housing, just above the differential housing. The bottom of the crank sensor is positioned next to the drive plate.

4-Cylinder Crank Sensor – 2.4L
6-Cylinder Crank Sensor – 2.7L
The reluctor ring notches is a multi-notched timing ring pressed onto the crankshaft. It works with the CKP sensor to identify crankshaft position. The crankshaft position sensor generates pulses of output voltage when a notch aligns with the the sensor.
When part of the counterweight alight with he crank sensor the output voltage drops to less than 0.5 volts. When a notch aligns with the sensor, voltage peaks to 5.0 volts. When a group of notches pass under the crank sensor the output voltage pulses from low to high then back to low. The sensor helps control ignition timing and fuel injection.
Symptoms of a bad or failing crankshaft position sensor include difficulty starting the engine, motor cranks but won't start, intermittent stalling and check engine light illuminates. Aftermarket sensors are fairly cheap as compared to OEM sensors.
