How to check the crankshaft and camshaft position?
Attach the black multimeter cable to battery ground. Cranking the engine, you should see the voltage reading on the meter fluctuate. Note that a damaged or improperly aligned tone ring will also prevent proper sensor operation. When in doubt, remove the cam gear and the crankshaft harmonic balancer and inspect the tone rings.
How does the crankshaft position sensor ( CKP ) work?
The crankshaft position sensor (CKP) relays crankshaft position and engine RPM to the PCM, or ignition module. This information is used but the PCM to control ignition timing, and in some applications, it is also used to control fuel injection.
How does the Camshaft Position Sensor ( CMP ) work?
The camshaft position sensor (CMP) is used to determine the position of the camshaft (s). It relays this information to the powertrain control module (PCM). The PCM then uses this information to control the fuel injectors, and on some applications, for ignition timing.

What causes the crank position sensor to go out of alignment?
It is typically thrown when the Crankshaft Position Sensor and the Camshaft Position Sensor are out of alignment by a certain number of degrees, or if there is an issue with the wiring, or one of the sensors themselves may have gone bad. We’ll explore the symptoms and causes directly below.
What does sensor a throw on a CTS mean?
In this case it’s sensor “B”, Sensor “A” throws P0016 P0017 should be considered an important trouble code to diagnose and repair. The crank and cam sensors work in tandem to produce the ideal air/fuel ratio for your engine. When this timing is off, the engine will typically not run (or barely run).
Why does my Saturn Outlook keep throwing p0017?
P0017 in the Saturn Outlook is predominantly caused by a few different things. It is typically thrown when the Crankshaft Position Sensor and the Camshaft Position Sensor are out of alignment by a certain number of degrees, or if there is an issue with the wiring, or one of the sensors themselves may have gone bad.
