How does a CMP sensor work on a CKP sensor?
How does a CMP sensor work on a CKP sensor?
The CMP sensor operates in the same manner as the CKP sensor, except that with the CMP sensor, there are only two edges to detect. The PCM identifies camshaft position by registering the change from 5 to 0 volts or 0 to 5 volts, as signaled by the cam sensor.
Where is the cam Position Sensor ( CMP ) located?
The location of the cam position sensor (CMP) varies with the type of engine and ignition system. On DI systems, the cam sensor is integrated into the distributor; on other applications, it’s on the front of the engine and reads off the cam sprocket.
Where is the cam sensor located on a DI system?
On DI systems, the cam sensor is integrated into the distributor; on other applications, it’s on the front of the engine and reads off the cam sprocket. The PCM sends approximately 5 volts to a Hall effect sensor, which is required to operate the Hall effect chip and the electronics inside the cam sensor.
Do you need a crank signal to start a Chrysler engine?
For a Chrysler engine to start, the PCM must receive a good signal from both the CKP and CMP sensors. Once the engine is running, the cam signal is no longer needed for operation on vehicles built after 1996. However, the PCM needs the crank signal to diagnose a potential problem with the cam signal, and vice versa.

Where is the crankshaft position sensor located on a Dodge?
The Crankshaft Position Sensor ( CKP) is mounted to the transmission bellhousing at the left rear side of the engine block. Engine speed and crankshaft position are provided through the crankshaft position sensor. The sensor generates pulses that are the input sent to the Powertrain Control Module ( PCM ).
Where are the coils on a Chrysler ignition?
The PCM identifies camshaft position by registering the change from 5 to 0 volts or 0 to 5 volts, as signaled by the cam sensor. In Chrysler’s coil-on-plug ignitions, there’s one coil for each cylinder, and it’s attached to the engine directly above the spark plug.

Why is my crank position sensor not working?
Very good explanation Voltage variation on some system that could cause voltage drop and cause the crank position sensor not to output the back the PCM.. = won’t start or died.. the way i read it especially on Prior to 1996″ Voltage Reference.
